The Greatest Archaeological and Technological Discovery of Mankind

Login to view embedded media

I’ve studied the pyramids around the world since I was a kid, have climbed many of them in the American hemisphere, had tons of books on them since the 1980s, and was always intrigued by them. I have leaned more towards the power generation model theory, as the burial chamber theories are easily-debunked.

But this is really mind-blowing, and will be for those who never heard about the power generation model.

These look like giant Tesla coils.

Firearms Sig Sauer SSG-3000 7.62x51 (Imported, pre-SIGUSA).

Sig Sauer SSG-3000 chambered in 7.62x51, McMillan Tactical Stock, and Sig Sauer case. Comes with 2x Factory Sig 5rd mags, 3x 10rd Accurate Mag branded mags (2 of which are not pictured as they're still NIB). Does NOT include the NF ATACR, however I'd be happy to sell it alongside the rifle if I get a decent offer on it. This is an earlier import model SSG-3000, from before SIG USA's started production with the shoddy plastic stocks. It's not quite clone correct for a "Behind Enemy Lines" build, but it's the closest you will get with a pic rail. I am the original owner, and have shot around 300 rounds of M118LR through the barrel.

Please keep in mind that this rifle was not a safe queen, minor cosmetic blemishes on the stock and along the barrel are to be expected. If you're picky about that kinda thing, let me know and I'd be happy to take more detailed photos of said blemishes for you.

Looking to get $2900 OBO, asking price also includes free shipping/insurance to your FFL.

This rifle is also crossposted to tacswap, just in case you see it over there as well.

Accessories WTT: My 700LA Manners EH1 w/mini chassis for 700LA LRH

Seeing if there is any interest with anyone that wants to trade their 700LA Manners LRH for an EH1 for 700LA. It is in like new condition and proven to kill critters. I sent it to Manners for them to throw in the Mini chassis after I bought it. Barrel channel is proof sendero I believe. I would like an LRH with same specs (700LA with mini chassis) if anyone has one they want to swap with.

Send me what ya got. Not selling, only trading.

8.6 Blk reloading info

I've been working on starting to reload for 8.6 blk and figure it would be good to start a thread and share information specific to reloading.

Q has some tech data posted on their website here - https://liveqordie.com/86-technical-data/

Cartridge Print - https://store-fwcq7xdl4a.mybigcommerce.com/content/8.6BLK CARTRIDGE.pdf

Chamber Print - https://store-fwcq7xdl4a.mybigcommerce.com/content/8.6BLK CHAMBER.pdf

The first hurdle was figuring out a way to resize brass since factory brass I'd imagine is a ways out. I did manage to get my hands on a set of prototype 8.6 blk reloading dies that I'll be using.

Left is a Q head stamped piece of 8.6 blk brass, the right is once fired Hornady 6.5 Creedmoor

I noticed at first I was getting some ripples in the neck when I did a full length resize and neck up from 6.5 to 8.6 all in one step.

Running the brass through an Annealeez proved to give much better results when pushing the shoulder back.

SR25 Upper Compatibility

A few months ago I decided to jump into large frame ARs and at the time I thought there was basically two camps: the Armalite AR10 and the DPMS pattern. DPMS being far more popular (Areo, JP, countless others) and Armalite being the less common and proprietary option (there are several other proprietary options and some will get an honorable mention).

I initially decided on a GGP set (DPMS) which was very well made but after some struggles with the Ambi system, (it was resolved) I decided I wanted something different and I sold the set. It was at this point I realized there was a third camp, typically associated with the highest end of gas gun manufactures: Knight's Armament and the SR25. I wanted one, but there very limited configurations, 16" and 20" 308s and 22" 6.5 Creedmoor are the only options. And that is IF you can even get one, Knight's guns are not readily available at retail, and I have no intention of paying Gunbroker/ Gray market extortion prices.

But is Knight's design as exclusive as it seems? Not really as it turns out. There is design elements from both Armalite and DPMS. Also, other manufactures have followed the Knight's SR-25 pattern and have some compatibility. There are some resources that discuss difference between AR10 and DPMS, but almost all of them completely ignore the SR-25 as a standard. If you are a Knight's purist, I get it... this is meant to be a resource for the SR25 pattern. Also this is America and people will always customize/build whatever they want. This post is not for you... please move along....

The SR-25 Pattern is basically Armalite "slant cut" receivers, DPMS barrel extension, barrel nut, bolt, magazine and DPMS High Handguard (3/16 Tang)

So after doing some quick compatibility research, I ended up choosing an LMT lower receiver as my starting point. I found a blem MARS-H in stock at Big Texas Ordinance. And this is where the issue started :giggle:. Upper receivers with a Armalite "slant cut" and DPMS High compatibility were not readily available for this pattern. I decided to set out to find a an upper receiver that I could use with my LMT lower, DPMS High handguard of choice and DPMS internals (barrel, bolt, carrier ect.) and I preferred to have no forward assist.

I have been able to test fit Stag, Seekins, Mega, LMT and Knight's and a few other brands with varying success and ultimately found pretty much what I was looking for. A long the way I created a spread sheet with the information I gathered to help others with similar objectives. If you can add to this I would love your input, feel free to comment and I will add as information as needed. There are no resources for SR-25 compatible manufactures as far as I know, but we can start here.

The link to my spreadsheet is here. (The spreadsheet includes Centurion Arms, LaRue, V Seven, Type A, Noveski, Troy, Genesis CNC, ADM and all the other brands I could find with Armalite "slant cut" receiver.

Below is a list of the highlights from the spreadsheet.

Knight's Compatibility
Knight's SR-25:
This is what I have been looking to emulate.. not necessary clone... but for obvious reasons this is the top of the list. Drawbacks here are lack of availability, limited configuration, elitism and cost.

LMT MARS-H: Probably better than Knight's if I am honest... the best Ambi in the business and that monolithic design has a lot going for it. Only drawback is the proprietary barrel system. There is just one guy (I am aware of) who makes custom barrels for these, that's not great for longevity. On the other hand, Everyone who makes barrels is making DPMS compatible barrel... so LMT is a hard sell for me.

Stag Arms STAG-10: This was the first one I tried and it does function. One of the best solutions available… The fit is ok on the LMT lower, the lower over hangs the upper in a the rear and the Forward assist is kind of a bummer. Unrelated comment, as with most DPMS High pattern uppers, Knight's handguard's require hand fitting unless you want to live with a huge gap between the rail and the upper. A small mount of material must be removed from URX 3.1 and for URX 4s the receiver its self must be faced. Its a small amount of fitting but not for the uninitiated. (PM me if you want more details on how to fit knight's rails to DPMS uppers)

SMF Tactical TAC-10 : You have likely never heard of these guys. Its a small shop, very nice and helpful people I spoke with on the phone several times. This is not their main business and I had to beg them to make me an upper. It took a few weeks but I got one and I am sure they will make more. This was the best I have tried. It will take some hand fitting to make it perfect, but on the plus side, Knight's handguards fit without any fitting or trimming (normally required). There is some overhang but this could be and fit with files if you know what you are doing (I was a small parts fabricator for a few years). I'll post updates here as this progresses, waiting on a barrel from Craddock precision and I would like to find an LMT or Knight's BCG. (Considering a Seekins BCG if I come across one)

IMG_2546.JPEG


Seekins SP10: Probably the best option. semi monolithic is great. Readily available and out standing quality. I am not crazy about the triangle shaped handguard and the lack of options here. I have fit one of these on to my LMT lower and its a perfect fit. These are only available as a builder set or a complete gun. but no reason not to just do this if you are cool with the handguard.

Mega Arms MATEN: Really nice quality. Availability is good. Not a great option to mix with other brans but will work with some. This is great if you are looking for a game gun. Super heavy. The upper will function with Knight's lowers but fit is not great interferes with MARS-H ambi controls.

IMG_2318 (2).JPEG



Wilson Combat: These do NOT fit and are truly a proprietary design. I did order an upper to try. The geometry is totally different and there is no chance this can work. I was so disappointed I forgot to take pictures before I returned it. They do have a disclaimer on the website but, I tried it anyway. They did give me a refund without and issues, but it took close to month.

Armalite AR-10A: The lowers are compatible with Knight's uppers, take SR25 magazines (AR-10B do not use sr25 mags). But that is where compatibility stops. The uppers have a forward assist (not really into that), and a different thread pattern for the barrel nut, different barrel extension, bolt etc, etc,
Capture2.PNG


ADM UIC-10: I have seen pictures of these with and without forward assist. They wont breakup a builders set unfortunately. If some one has tried this let me know.

Edit: ADM UIC-10 do fit. (At least the geometry is the same) I found this pic randomly… still no information on the upper or if it has a forward assist)
IMG_6181.jpeg



In the longer term I have a friend with a CNC shop who is making AR-15 already and looking to get into AR10s. If there is interest in this pattern, ether for Knight's clones or just cause you think its cooler than other options let me know. I am trying to build a case that this is a space in the market where he can differentiate and find some demand.



EDIT: More options provided by SH members


JP Enterprises PSC-12 (Information an pictures courtesy of @papershredder ) My take on it so far on an LMT lower; Pins are very tight, no play or slop between the receivers at all. There is a little gap at the back angled profile between upper and lower receivers. They use a DPMS threaded barrel nut and come with any of the JP DPMS bolt carrier groups (buyers choice).


Edit: the JP option ended up not working out. Details on page 2 of this thread.

Which suppressor to use on my rifle? (Griffin 30SD-K or SiCo Specwar 762)

These are my two rifle suppressors I have at the time and curious which you'd recommend running on a PRS style rifle in 6GT. The Specwar is 9" and 24oz, but it threads on to a muzzle device and locks up fairly well. The Griffin 30SD-K is both shorter and lighter (17.5oz and 6.7") but uses GateLok so it has some slight movement to it. I'm not sure if that could induce any inaccuracy in the gun and if just going with a more secure lockup would be better than saving weight/length in an already long and heavy rifle.

The Essential Fundamentals Of Precision Long Range Rifle

 Long range shooting is a journey.  Little did I know, as a young Marine recruited to  Surveillance – Target Acquisition Platoon in 1986, that I would still be in this game some thirty-seven years later.  That is how some journeys are.  One doesn’t realize that a journey has been undertaken until  time passes and you find you are traveling the same path.



     The knowledge I acquired in that position was leading-edge for long range shooters of the time.  My instructors and mentors were a mix of competitive shooters and military snipers.  In those days the only shooters with any interest in ranges beyond short hunting ranges were of those two disciplines.



The Realization

     I  thought I had it all figured out.  The reality was I had acquired fundamentals and a small amount of knowledge, but had very little understanding...

SOLD FS: Attn2Detail mk1 small knife

Zelle, PayPal friends and family no notes

$old


Attn2Detail Mark-1 small. Magnacut blade. Titanium handles.


Carried 3 times. Factory edge, cut some tags off clothes and that's been it. I'm the orginal owner.

I took a pic of it, on the handle edge, by the blade there is some small indentations, just part of the manufacturing process I guess. It came from knifejoy like that. The overall length is listed as 6.25" so it's smaller.
