Could someone with an A2 handguard/ forearm please measure, and post, the internal diameter? Thank you
Just cut out the foam for my SRSA-1
My A2 covert is 1.488” left to right, 1.508” top to bottom. But the barrel is slightly off set towards the top of the HG, leaving only .215” from top of barrel to HG.

No, I shoot suppressed nearly all the time now so most of the mirage will be from the can. A wrap helps there but it's not 100% effective. I'm thinking about getting a longer handguard to replace my Covert to see if it helps at all.
Also, here's a quick picture of my "washer mod". I shimmed only the screw behind the magazine. I tried it several variations of the screw in front and behind and found that (at least for my set of skins) the one behind the magazine was the only one that helped loosen up the fit. I used the same shims (0.010" Thickness, 1/4" ID, 3/8" OD) I use to tighten up receiver fit on AR15s (one shim on the pivot pin is all it takes), available on Amazon here: https://smile.amazon.com/gp/product/B006U1RWU4
For the mags to fully drop free at any angle I needed 4, though you can see there's not a lot of tension on there as I didn't want to tighten the shimmed screw down too hard, there being no reason to do so. With some threadlock tape, none of the screws are going to loosen up by themselves and they're not holding or supporting anything critical. If you feel more comfortable cranking down on plastic, 3 would suffice if you take up the space in between them.
Anyone using an Elite Iron bipod or similar? Thinking about an upgrade to a Cyke-pod or Elite Iron, leaning toward the latter. My rational is a more stable platform that helps with recoil and staying on target.
This is a pretty common theme. Buy the elite iron and don’t look back, it’s that good.
If anyone is interested, I have my 3x fired 300 Norma barrel, bolt, mag, ammo, etc up for sale

26” barrel, standard GAP reamer. Spun up a few years ago by/with Ty.
Berger 130 VLDH: 3180 FPS with 60.5 H1000.
Hornady 140 SST: 3050 FPS with 59.0 H1000. One hole groups. Got it up to 3100 at 60.5, but accuracy fell off.
Hornady 140 SST: 3220 FPS with 60.0 RE26. Showing signs of pressure, I should have started lower. I only had a pound, now it’s nowhere to be found. More investigation needed with Reloader 26. Was going to try other bullets but wanted to use up the SST’s.
I suggest you get the magazine kit from SAC. It’s made a huge confidence booster in running the SAUM with these magazine and functioning flawlessly.

I have two modified mags from when Dan was doing them. I have tried for months to get some rl26, I have cane close to some on the classifieds of different pages but either sells before I see it or too far to drive. I plan on using 130 hybrids and h1000 for now, but will probably run 140 hybrids most of the time. I went with a 30" barrel to get more velocity.
I'm getting 3310 out of 120 VLD with H1000 at 63 grains. You will love it. I just used HS Precision mag tool and bent the feed lips out, works flawless!
It looks like my ES Tactical barrel shipped yesterday... I have to sit here all weekend wanting to shoot knowing my barrel is in the mail. lol Before anyone ask, 16.5" 6.5CM barrel. Nothing fancy, but exactly what I need at the moment.
Now to decide if I want to sell my .300WM barrel and go .300PRC for my 800+ yards barrel.

That wait does suck. Eric shipped me two barrels and somehow Fedex screwed up and only the 65CM barrel showed up and they lost the 338LM barrel. Had to wait two weeks for them to find it.
You should have Eric rechamber the 300WM into 300PRC.
Considered this, but also considering a carbon stick. I don't have to decide for another 3-4 months at this point.
In my experience, making a marginal jump up isn’t always worth the time and effort. So if it can’t be done with a 300 WM, can it really be done with a 300 PRC? Yes, no belt to deal with.
I’d make a more substantial jump and go 33XC or 37XC.
That said those are questions you need to ask and answer for yourself. Is the juice worth the squeeze?

To clarify, I am only considering a switch due to wanting to try a heavy contour carbon barrel. If I'm getting a new barrel, I might as well consider the switch... but at the same time, the .300wm does its job just fine at the moment as my range is limited to about 400yds.

Nice, Where's the bolt cutout, or is the case wide enough to fit with the bolt installed ?

I just built a barrel in 33XC for my Gen 1 SRS with the short Covert handguard. It seems to be worth the effort in gaining about 400 fps over the 338 Lapua. I've only got 50rds down the pipe so far with load development and I'm getting 3380 fps out of 265gr Cutting Edge Lazers. I've really only tried Reloader 33 so far and hope to find something else down the line but no time now. I am going to a long range shoot in a couple weeks so have to load up ammo with the data I've got. I verified my load yesterday with a new lot of powder and found it to be a bit hotter and a little slower. One reason to try something other than RL33.
The range has targets from 100 to 2000 yds and will have targets out to 3000 for this shoot. Last summer my friend made it out to 2700 which was the extent of the range at the time. He was shooting an HTI in 375 Cheytac. We made him a 36" barrel for this years shoot and he's running 400gr Cutting edge Lazers at the same speed his 350's were going last year. Should be exciting.
The DT has a great ability to allow such a wide variety of caliber choices and that means we can cover a lot of requirements with one rifle. It would really suck to have to buy a scope for the number of rifles I've got DT barrels made up in.

I’m waiting on a barrel for a 6.5PRC and have a question about the magazines. Will the LA 300/338 mags work with the 6.5prc without having to mod them?
It’s wide enough to leave it in. I only have one bolt so far, with two more on the way. I’ll make new cuts for those and the new barrels when they arrive.
I wouldn’t shoot it that much either, likely just a few times per year. But to be able to say I’m good to 2500 yards or so is something I’m finding hard to overlook. The 33XC would replace the 300 WM and my 260 can handle everything inside 800, so I’d have little use for the 6.5 SAUM at that point.
Yes it does and very well too. In fact I haven't used any mags for quite some time. The only issue is if you slowly open the bolt and the round drops into the sled instead of ejecting. 338 Lapua and longer are a pain to get out so I just pop them back into the chamber and open the bolt quicker. It drops the case out better that way. I am getting a delamination down toward the bottom where the lug on the front is. I have to keep my friends from slamming the thing into the magwell when they put it back after looking it over. Thinking about making one from aluminum... Can you 3D print aluminum yet?
As for the guys on the fence you need to decide if the 33XC is something you really want or just another cal out there to drool over. If you have the range to stretch it out its a no brainer. If you're stuck in the midwest thinking 500 yds is a long way to shoot than the 308 should be enough. I don't get out where I can shoot long distance very often but its worth it to me to be able to when I can. The 338 Lapua has been a great one for most of these trips but folks keep stretching the distance and its tough to keep up with the joneses.

I was offered Gen 2 SRS A1 chassis with mono pod for 1600.00. Is it really worth 1k more for the newest chassis? Will I gain that much accuracy from it.
Buy it. I was working up a load in my 6XC 95 gr LRX on Sunday with my lowly, outdated SRS A1. The SRS A2 has to be more accurate than this.
Think I settled on 40.5 gr H4350, 3170 FPS, SD 7.4 with the Barnes 95 LRX. 40.0 also works at 3130.

Considering that's about half price from what an A1 chassis used to go for before the A2 release, I'd say if it's not beat to hell, that's a steal. I know DT has their A2 marketing numbers, but there are many A1 chassis out there (including mine) that couldn't possibly be more accurate.
Just a chassis for now. I’ll be on the hunt for caliber conversions. I also picked up my scope, a Bushnell XRS II 4.5-30 Illuminated.
The only sticker I have ever put on any of my vehicles. I’m sure you could contact the factory of one?
Great plan @cypriss32 . I picked up a used .308 barrel for $650, and have seen multiple used tubes run for $800. Obviously there are certain calibers that are less attractive used because they burn out quickly.
Welcome and I hope you enjoy the system.
My best advice to a new owner is to spend time cycling the bolt and making the motion feel normal. Trigger is very good, but not like a trigger tech or something. But it didn’t cause any issues for me at all.

Agreed! Time cycling that bolt for sure. I did the primal rights trigger mod on mine and WOW! Zero creep, breaks like a tiny glass rod at exactly 2lbs.
Do you have more info on the Primal Rights trigger mod? I don't see any information on their website about something like that.
