New SPUHR IDEAL CHASSIS SYSTEM (SICS)

Hi,

Lets put the 2 rendered models top to bottom for ease of conversations.

Can someone start from the recoil pad and line out the similarities?

Hi,

Yea, still not seeing it. You gave no details as to what lead you to say that.

So...
JP is in MN, you are in MN...
You have nothing but JP business information in your signature and more than half your post on SH are about JP in some way or the other.....So are you directly connected to them or how does that work?

Sincerely,
Theis
Covered handguard, folding stock, good quality. All I said was that it looked like a JP. I could have said that about any other chassis. I'm a JP fan and, so far, I have no reason to think the Spur is any better or worse than anything else I've seen. It's an opinion. The pictures I put up were intended to allow you to make comparisons yourself. The APAC is solid. The folder locks up like a bank vault. It's a great chassis.

Exactly, but I think the Spuhr SICS have a few clever things than one may or may not like - some for the sake of it. From "not invented here" to "I don't like the color".

I have a lot of JPs as well, love'em.


For the record, if it adds anything new but easier to read everything in one page.

SICS™Feature 1 - The Forend
The SICS™ 16” standard forend features Spuhr Interfaces™ along the top, sides, and bottom, QD sling swivel cups, and an integrated ARCA Swiss® rail for use of various commonly available bipod and tripod solutions. The SICS™ can also be fitted with different length forends depending on user requirements.
The proprietary ARCA Rail Grabber allows the user to quickly adjust the grabber’s position along the full length of the SICS™ forend with a mere push of a button. Instant and secure.
With all SICS™ forends, a short Picatinny Gen2 rail is included so that a bipod or other 3rd party accessories can be attached to the chassis.
Finally, the Spuhr Interfaces™ along the forend also allow the use of other Spuhr ISMS™ scope mount accessories to be moved from the scope mount to the chassis, and vice versa.

SICS™ Feature 2 - The Chassis Body
The SICS™ Chassis Body is machined from a single billet of 7075 T651 aluminum alloy, and is designed to provide the most rigid cradle possible for the barreled action, as to achieve the highest possible degree of accuracy and precision from the rifle system.
The first step in the design process was to ensure that the forend attaches in front of the action so that any side forces onto the forend do not spread to the chassis body or to the barreled action.
The next step was to choose a magazine, where we opted for the tried and true AICS pattern magazine well, thus achieving a stronger chassis body, by using a magazine that locks from the bottom rear than from the side, as well as allowing the user a wider range of sources for magazines than a single brand. (We also offer an extended magazine stop for gunsmith fitting for those who need them.)
We also extended the sides of the magazine well forward, so that they provide a natural barricade stop without impacting the barreled action or the forend.
The third step was to fit the chassis body with a comfortable grip. We naturally chose to design the SICS™ Chassis Body to accept most aftermarket AR15 pistol grips, but in the end we opted to design and fit the SICS™ with our own rubberized grip design. To ensure that the pistol grip is as comfortable as possible we made it adjustable, with 8 mm/0.32” of travel, to perfectly align your trigger finger with the trigger.
Though the pistol grip does not feature a thumb shelf, we have created a natural resting place for the shooting hand above the rear of the pistol grip.
As a compliment to the QD sling cups on top of the forend, a third QD sling cup is attached to the rear left side of the chassis body.
Finally, we added Spuhr Interfaces™ to the sides of the mag well, so that cartridge holders and other accessories can be attached there. Competition shooters may want to attach accessories such as timers or DOPE card holders, etc., to the rifle even if they chose not to use one of our ISMS™ scope mounts.

SICS™ Feature 3 - The Folding Stock Frame
The SICS™ Folding Stock Frame is machined from a single billet of 7075 T651 aluminum alloy, just like the SICS™ chassis body, and is designed to provide a rigid but lightweight folding stock.
The Folding Stock Frame attaches to the Chassis Body through a hinge with an M8 Hinge Bolt with brass bushings. From the factory, the hinge is adjusted for a smooth and silent movement without any unnecessary play. If the user wants to adjust the movement this can be easily done using a 1/2” socket wrench.
In the folded position, a stud on the Folding Stock Frame locks into the side of the Chassis Body while the Folding Stock Frame prevents the bolt handle from moving.
Locking the Folding Stock Frame to the Chassis Body in the extended position is a push-button steel latch that locks solidly into an adjustable steel lock plate in the Chassis Body. This allows the user to easily adjust the lockup over the lifespan of the chassis, regardless of how much use or abuse you subject it to.
The Folding Stock Frame features an adjustable rubberized cheek piece. The height of the cheek piece can be adjusted by turning the wing nut on the left side of the Folding Stock Frame, while moving the cheek piece up or down. The wing nut’s rotation can also be adjusted while pulling on it, without impeding the lockup of the cheek piece. A spring-loaded detent prevents the cheek piece from accidentally being slid out of it’s dovetail track. By loosening three Torx 20 screws, the cheek piece can be adjusted forward or to the rear, and spare screws can be stored in the stem of the cheek piece slide.
The Folding Stock Frame also features a bag rider, into the bottom of which there is a row of Spuhr Interfaces™, so that accessories such as Picatinny rails for butt spikes, etc., can be attached. We have also machined holes through the sides of the bag rider so that bags can be tied to the bag rider with a piece of paracord, etc.
Among the various accessories we will offer for the SICS™ is a side adjustable cheek piece and a height adjustable bag rider.

SICS™ Feature 4 - The LOP Adjustment and Butt Plate Assembly
If we were to narrow down the SICS™ to a single feature that sets it apart from other chassis on the market it would be our patented quick-adjustable Length-of-Pull (LOP). By pulling to the rear on the LOP Adjustment Lever, housed behind the bag rider, the SICS™ Butt Plate Assembly can quickly be extended 50 mm/1.97” or to the required length. To reduce the LOP, just pinch the LOP Adjustment Lever and the grip of the LOP Retaining plate together and push the assembly forward.
If the user wants to set their own maximum and minimum LOP, this can easily be done by adding LOP Presets into the side of the Tufram coated LOP Bar. It just so happens that these LOP Presets are the same M4x10 Torx 20 screws we use for the top covers on our ISMS™ and Hunting Series rings and mounts. Also, the top of the LOP Bar is engraved with numbers, visibly indicating the LOP position for easy confirmation.
In addition to the quick-adjustable LOP, the SICS™ also features a height-adjustable butt plate, which allows the butt plate to be raised 32 mm/1.25” in three steps, to ensure a more comfortable shooting experience when shooting from the prone position. To adjust the butt plate height, just push the button on the left side of the butt plate while sliding the butt plate up or down.
Finally, at the rear of the butt plate, we use a Limbsaver® Airtech® recoil pad for maximum recoil absorption.
Among the various accessories we offer for the SICS™ is a 18 mm/0.71" Recoil Pad Spacer, for shooters who require additional length of pull.

SICS™ Feature 5 - The System and the Accessories

The SICS™ ships standard in hardcoat anodized black, with a 16” Spuhr Interface™ forend, and is designed for AICS pattern magazines. LOP is quick-adjustable for 50 mm/1.93”, pistol grip 8 mm/0 32", and the butt plate can be raised 32 mm/1.25”.
The Short Action versions for Remington 700 and Tikka T3x are 685 mm/27.0” folded and 975 mm/38.4” fully extended.
The Remington 700 SA version weighs 2.37 kg/5.22 lb and the Tikka T3x SA version weighs 2.43 kg/5.35 lb.
Remington 700 and Tikka T3x Long Action versions will be available by the beginning of Q1 2022.

As to accessories…

The ARCA Swiss Rail Grabber (SKU CA001) is designed for quick and tool-less push-button adjustment of the grabber’s position along the forend. The CA001 has an ARCA Swiss interface surface with a Spuhr Interface™ machined into it, so that an ARCA bipod or tripod can be attached, or alternatively a short Picatinny rail, etc., if a bipod with a Picatinny grabber needs to be used. The CA001 weighs 120 gr/4.2 oz.

An oversized magazine catch, in-the-white (SKU CA002,) is available for those who need to be able to custom fit their magazines into the SICS™.

An exterior weight kit (SKU CA003,) containing two Corr-I-dur® treated steel weights for the SICS™ forend, is available for those who want to add weight to their rifle. Each weight weighs 110 grams/3.9 oz (including three screws) and is 58x30x10 mm (2.28”x1.18”x0.39”). The exterior weights are also sold as a 5-pack (SKU CA008).

We also offer an interior weight kit (SKU CA004,) containing two Corr-I-dur® treated steel weights designed for the inside of the SICS™ forend. Each weight weighs 171 grams/6.0 oz (including three screws) and is 58x36x12 mm (2.28”x1.42”x0.47”). The interior weights are also sold as a 5-pack (SKU CA009).

Finally, we offer an 18 mm/0.71" recoil pad spacer (SKU CA005,) for shooters who require a longer length of pull than what the SICS™ offers from the factory.

Other accessories currently in the works are an Adjustable Bag Rider and a Side-Adjustable Cheek Piece

Well, that video could be half as long, and still get the point across. But it showed some details I was curious about.
I think the SICS looks great, and I am a big fan of KRG too, been running their stuff for years.

The reason why sics at all was designed is because I didnt like anything on the market sufficiently to use it.

LOP
First priority is the LOP length of pull, but not LOP in the traditional manners as buttplate to trigger but instead buttplate to scope.
Modern high magnified optics are really picky to where eye is and I use considerably longer LOP in Prone than other positions.
That is the reason why I used TRG folder for many years, to simply be able to change LOP even during a stage.
So i want a LOP change that takes 1-2 seconds and can be preset for your min and Max.
And LOP adjustment should be with zero play, and guess what?
We have that, and as far as i know it’s the only chassi on the market that offers it.

It’s not only about different positions as its also different clothing, ballistic wests, different users. Different users can just as well be different snipers as wife and kids who should have a fair chance to reach scope.

As said noone else offers it, so comparing this chassi to JP or KRG is not even remotedly relevant.

Folder
Many folders I have used get a play after a while, and its annoying.
So our hinge is with built on Bronze bushings as alu don’t work good against alu. And the lock is adjustable so you can easaly adjust away with any play that can come in the future.

Grip
Lengtwise adjustable and AR compatible.
What more Do you want?

Forend
Yes enclosed as there is quite a few forends out there that not is very stabile and some give a lot of harmonics.
The chassi ”sings” when you fire it.
We designed the forend to not sing and be stabile.

Reiciver/middle section
Designed to be high to gives maximum support for the action.
The more ridgid the action is the better the gun possibly can shoot, and the heavyer barrels it can take.

Slider
We make this special really fast slider so bipod very fast can be moved from front to rear or vise versa.

Cheekpiece and buttplate
Toolless adjustable.

Ugly
Yes and no
It’s in the eye of the beholder….
When you know and understand why everything is designed as it is, you will not find it ugly as it’s designed around the funktionality.

Availibility and timing
Our intention was to make a great introduction in september, something We clearly failed. Intention was further to start shipping there and We had lots in stock.
But a few small parts was found to be not to the expectaions and We machined new parts (just a few minor parts But it halted the start)

I am very happy with the chassis.
Here is a number of interesting designfeatures noone else offers and machining quality is second to none.
I am really sorry for the failed intro, But end result turned out great!

I'm not sold on the look but I agree, form follows function. I can look past that.

I'm keen. I'm in Australia. Who, how much, when?

I believe the Eurooptic video on YT mentions it, 13" minimum?

First impressions are really good, very solid/overbuilt but not too heavy. I'll really enjoy having full arca for tripod use, and the arca bipod slider is definitely nice for shooting off of shorter platforms. I've seen a few people lament at its lack of a thumb shelf, but the stock hinge functions as one perfectly for me.

As the cost on chassis in general gets more top end, I keep wondering how well the Habu would sell right now, and at what cost.


Spur is really going to have to sell me on their chassis. At this point I'd be inclined to go with the krg c-4 at the $2k price point, or sticking with an MDT. I'm not seeing anything spur offers that's new or improved. I'm sure it'll be a top quality product, but I haven't had any quality issues with any other chassis system.

Fair point, in the precision rifle world I view anything in the $1500-1800 as essentially the same price so I lump the SICS in with the higher end MDT and KRG chassis and that was my basis for comparison. I sold my stock chassis for $600 and thought it was worth it going for the SICS at $1299 net.

After 12 years as a nerd AR/M4 armorer my brain just defaults Spuhr to the Geissele category. Not everyone sees the value in a URG-i upper or a SMR rail, nor is the value there for some use cases. The adjustments on the SICS seem to be some of the most refined and well thought out in the game, from what I've seen so far. Things like that, the accessory commonality with my mount, long foreend/full arca, and enclosed barrel bridge out of the box all area reasons I figured why not give it a try. Not to mention the stock is all latch/cross bar adjustment vs threading in and out adjustments. Not a huge deal, just personal preference.

Hi Much520,
Without using the folder, is the buttplate/assembly able to be move downwards enough for cleaning of the barrel? (Legality reasons, the folder would need to be diactived, hence the question)
Appreciated

Yes it does!
 
That one's from Hoptic, great people! I was trying to find direct-mount options for the Spuhr chassis and this single-screw was one of their new options. Just got back from a 2-day course and it was super solid, no issues.

Love it. What specific questions do you have?
Really like the look of the chassis on paper but can't find a single review online. Seems to be the chassis that everyone was interested in learning more about but very few people actually bought - which I found weird. I assume build quality is excellent but I'd be curious to know how the moving parts are holding up under use and in dirty/dusty conditions? 'Love it' is a pretty sound endorsement - would you choose it again given what you know now? Anything fail to meet expectations? Thanks!

Everyone was interested? This thread only got to two pages. I think there was another with a small amount of activity. But it seems manufacturers don't get far in the PRS market without sponsorships.
 
Saying "designed for PRS" is not some magical buzz word which sells stuff. And lots of the "prs" gear is NOT prs gear.

Ok i said it. Yeah, i got skills. What ya gonna do about it ?

PRS has become a synonym for expected higher quality, modularity, adjustments and rail interface just like Mil-Spec was in the 80-90's and tactical in the early 2000's

there is only so much you can do within the limits of weight, price and rifle sized form factors

and only so many materials that fit the requirement matrix

the spuhr while a nice piece of kit is also a few dollars more than the competition...and the competition isnt junk...so its a hard sell at times

I pretty much felt the exact same way about it, and the lack of talking and writing about the SICS is still a bit weird. At least to me.
But, a few weeks ago at a local PRS type training match I got to fondle a SICS for the first time and I feel very much that the hype is real. It felt rock solid in every way. The folder locks up like a vault and the adjustable LOP feels the same way. Now, I still dont feel like the quick LOP adjustment is something that I personally would use, I usually set my rifles up with one LOP and run it that way no matter what position I have to get in, but anyways. The fit and finish was as you can expect from Spuhr, excellent.
Now, If they decide to make a SICS for the TRG I might be tempted. But as it is, I am very happy with my KRG/Vision mash up too.

I think it would've been more popular if they had released it properly. The drop itself was meh and then they got it into the hands of like zero industry professionals for review/press. It's a really saturated market, IMO something like this needs to be in the hands of IPs/SMEs very early on so that those guys can call out the competitive advantages and differences. Without name dropping, I've personally been around a couple of industry studs that either have a SICS or have good things to say about them but never got any info or demo units. They really like it, with few gripes. But there wasn't enough push there to pull them away from the usual suspects (MDT, KRG).
This is the only comprehensive non trade show review I've seen:

Yes definitely overbuilt, and quality that you'd expect from Spuhr. Yep, completely functioning as advertised and I like how under speed/stress all the controls (hinge, LOP, etc.) are very easy to manipulate.

1000% would buy it again, wouldn't change a thing. Go buy one lol.

After playing with one, I didnt mind it, but Im not gonna add one to the collection. Machining is top tier - but there were a few details I didnt love personally. Not massive things, but in a market of 1000 chassis, it doesnt take much to go from a purchase to a miss.

Can I ask what were the few things about the chassis that you saw as a negative?

For those of you that have the SICS already in-hand, do you happen to know if the Defiance Elite with the extended thread length will fit? I happen to be running this action with a ARC Barloc, and I'm worried that there might be something prohibiting me from bolting down the action. Thanks in advance for your help!
