The A1 Trigger is better, IMHO.

I traded to the covert forend for weight purposes when I got the A2. But I have a larger hand than normal and the trigger pull can’t be adjusted on the A2. That kind of sucks. May end up adding a little padding where the web of my hand touches the grip to help trigger pull distance.

Does someone know the factory barrel profile's measurements? Specifically on a 22".

I have been shooting my SRS A1 and Covert set ups for a good while now. When did they release the A2 and what is different from the A1's? Are barrels interchangeable?
The barrels are interchangeable between the SRS-A2, SRS-A1, and the older Gen 2. I know of people show have purchased the new SRS-A2 chassis and used their conversion kits from the SRS-A1 chassis. Or in my case I have a new conversion kit in my 5 year old Gen 2 SRS. The only chassis that is different as far as compatibility with barrels is the Gen 1 SRS (the original design). And even then it's just a different barrel extension. You could could take off a Gen 1 barrel extension and attach a Gen 2 barrel extension. The would allow the old Gen 1 barrel to be used in the new chassis.

How many times do you think compatibility amongst different DT iterations has been brought up in this 245 page thread? Between barrel extensions and fore ends I’ll bet it’s at least 25. Perhaps we need a sticky within the thread, so the first post on each page is a compatibility chart?

It has been brought up too many times. Even though it is kind of understandable with new people coming on. I like the sticky idea or a simple link to a chart that shows all the changes over the different revisions. I'll write something up and see if it makes sense to post on a website or just a simple sticky like you said.

The question about extension/barrel compatibility does get asked a lot but I think it’s normal. I don’t mind answering the question. Not everyone goes through all 200+ pages of a thread prior to buying a Desert Tech rifle like I did. I think every question about our rifles has been addressed in the vast reaches of this forum space.

If I had a 223 conversion I would have a dedicated bolt.

Have a couple questions.

1. Has anyone found a decent soft case besides the DT one? I don’t think I want to spend $300. I have 2 barrels, 2 magazines & 2 bolts.

2. I know someone mentioned a sling that was really good for a heavier rifle. I think it had backpack straps but I can’t find it. Anyone know which it was or want to make a rec for a good sling for the rifle.

I only use a hard case for them. I use the TAB gear pinnacle sling. They have the biathlon sling that I think has straps.

About as much as questions about ring height, trigger adjustment, covert vs recon, and on and on. Nature of an open internet forum. Topics come up over and over again. There will always be those who feel they are fully in the "know" annoyed by questions they feel below their level of investment in said thread or topic. It's been that way since I started here in 2009 and probably every open board on any topic on the web. There is no way around it and it will always be that way. In my estimation it's worth it for open exchange of information. Perhaps a closed DT thread with a 100 question test to qualify for the privilege to ask a question would alleviate the woes of redundancy for the elite:p

Seriously though there is likely not a good solution because I am well indoctrinated having been around here for a long time and using the DT platform for years and still triggered animosity from a few. It's why I spend most of my time shooting and not keeping up with the latest ebb and flow on the Hide and why i didn't even know a new DT generation was even released. Was my post a poor one? Probably. Going to happen again in the next 20 pages? POH 100%. My mistake.

There is a Desert Tech section with tons of good info on the SRS under “resources”, but there’s no real way for someone new to know about it except by chance.


Most of the repetitive questions can be answered there. If you want to truly help someone with basic questions that have been answered many times before, refer them to that. It’s a pretty damn good compilation of information.

Hi,
does anyone know who might have some Desert Tech blanks in stock.
Can you also use heavy varmint blanks with their 5" 1.250 parallel ?

Put on a Hoptic USA bullet quiver on my SRSA-1 today. I really like it. Wish it could be a little further back. It’s still an easy reach. 26E81354-4C8C-4C64-A2E7-DADCB14EE5C8.jpeg

I've never seen DT spec blanks for sale but maybe someone does have them. I buy straight cylindrical blanks of 1.275" diameter or larger so that I can turn the down to exactly 1.25 for the clamping surface. I don't trust most of the center turned blanks to be within the spec of the necessary dimensions for the barrel. It means a little more work for me to turn off all the excess but things work out well in the end. Check with any of the barrel makers and just let them know you must have a minimum finish diameter of 1.250 + 0 -.001 so you need a larger diameter than that for your blank.

Well got to finally get to run my DTA Hard yesterday. I feel very at home with it and now going to part ways with my other conventional rifle. I’ve had for 19 yrs.The only upgrades are the rails to aluminum and possibly a wider bipod foot print.

Any spare parts should I have in the bag for the A1

I do have a spare trigger pack and bolt pins/springs/extractor but I have been through a bunch of rounds and shot out a couple barrels on one chassis with no issues. I doubt you'll ever need any spare parts.

Ok, I need some help. Every time I change barrels, I lose zero. My E-S Tactical barrel moves 1-1.5 MOA @ 100 yards each time. Up, down, right, left. I un-tension the bolts nearest the muzzle first to furthest from the muzzle and re-torque nearest to furthest. When I insert the barrel into the chassis, I turn the barrel counter clockwise seating it before closing the bolt.

My Short Action Customs barrel seems to be much better and I do it exactly the same.

The only thing I don’t do is use the barrel lock on the ES-Tactical barrel.

Anyone want to offer any advice? I’ll take it

New barrel or new issue that just started? I never use the barrel lock. Hold chassis vertical, drop barrel straight in, lock bolt, torque from muzzle to stock. I am yet to have an issue.

I didn't notice any shift with mine yet. I'll have to do more testing.

Are you shooting on big temperature shift days and with hand loads or Factory ammo? Prone each time or from a bench each time?

New A2 chassis and new barrels. Have had this problem from the beginning. Chassis is vertical during the barrel change.

I have shot in situations with both swings and stable. I am always using factory ammo. I have shot from both prone and bench With no discernible difference in results.

We had the RRS spec ARCA/Dovetail rails show up last week for the SRS A2 and Covert A2 rifles.

We have full length rails for both the SRS A2 and Covert A2 chassis. These rails go from the muzzle end of the hand guard back to the trigger guard. We also have a short rail that is 5" long and goes from the trigger guard to the first couple inches of the hand guard. The short rail will mount on with the SRS A2 or Covert A2.

An addition to the ARCA rails. Special Purpose Rifles worked with Sawtooth rifles to make a 1.5 RRS rail for the SRS-A2/Covert M-LOK hand guard that extends all the back to the trigger guard using the integrated tripod mount in the chassis. Link to website below

Why would the barrel rotate when you close the bolt? Are you putting Gen 2 barrel extensions in a gen 1 rifle? My gen 1 barrels have no slop and neither do the gen 2's. The only time I can get any slop is with the gen 2 extensions in the gen 1 rifle.

I've had a pretty good number of barrels in my gen 1 rifle and never saw any shift in zero with a particular barrel regardless of what order I tightened screws, or whether I used the lock or not. The same is true of the Gen 2 rifles I've been making barrels for for the last 10 years. I have noted that the zero does change from barrel to barrel but usually not by much and that is something I'd expect. Every barrel is going to be a little different so changes in zero should be expected.

Now one thing I can see as a possibility for you is that your barrels aren't all the same diameter where the clamps hold them. If there is any taper it can affect the clamping and then the order of tightening might make a difference. Check your barrels with a good micrometer. Measure from right in front of the barrel extension about every half inch out to 5 inches past the extension. Measure again at 90 degrees from the first set. You should get 1.250" at all locations with no taper or out of round and dimensions bigger than 1.250 can be a problem. According to the original spec for the barrels the tolerance was + 0.000 and - 0.001 so there is only a .001" tolerance on that part. Keep it that way and there should be no zero issues. If its not right it could be the problem. Some makers aren't keeping the tolerance so keep this in mind when looking at pricing. Sometimes you get what you pay for and sometimes you don't.

One more little detail I keep meaning to mention and forget is that guys want cerakoted barrels and neglect to consider that it will affect the clamp up on the barrel. If you're getting your barrels painted you should mask off the section that is clamped in the receiver. I have had to sand off a few customer barrels that they had cerakoted because they would no longer fit in the receiver. Even if they're not so oversized they won't fit you are affecting a part of the barrel that is key in the accuracy dept. Don't add another variable to the already complex equation of accuracy.

When I say rotate, it is before I close the bolt. The barrel can rotate a bit back and forth when it is proper position. I always rotate mine to the max counter clockwise just in case so when I close the bolt, it will already be in the counter clockwise most position.

The ES Tactical barrel has no ceracote and the SAC barrel is ceracoted but not on the extension.
