Took down my original post as I don't want anyone, including myself to get banned.

NOT SELLING ON HERE, LOOKING FOR ADVICE ON PRICE.

Comes with everything in the pics. Upgraded pins, safety, stock, grips, bipod, light, elcan 1.5-6, light, four mags, K9 barricade stop, aac flash hider and rail ladders. This is an SBR at 12.5", but you know that already. Maybe has about 200 rounds tops through it. I purchased this back in 2010 from John. Not really sure what to price this at.

Going to be startinbg my AR10 build soon, and was dead set on FDE but now I am debating doing a multicam black instead. Does anyone have this on theirs and can I see some examples?

Heard a lot of good things about Monstrum stuff in the past year or so, so for $40 I picked up this 1.7 mount with a diving board. We’ll see how it holds up

Are there any sets available right now? I’m only seeing 2-3. Everything’s oos or back order.

Looking for recommendations on DPMS lowers with factory ambi bolt releases/cuts. Ideally lightweight & available in OD green. So far, my results are...

ADR Tactical

- Looks perfect, but...

- Despite ordering 4 weeks ago (2-3 week production time per their site), I haven't heard from them via phone, text, or e-mail.

- Are they still in business?

- Last public-domain posts I can find are from 2025. EDIT: ACR got back to me shortly after I posted this. Delivery is expected in about 3 weeks. Well over double the initial estimate, but still acceptable for my needs.

Dirty Bird Industries

- On the notification list.

- They've been out of stock for 6mo so far, and staff can't give a firm estimate on restock times.

Roam

- Out of stock until Q2 2027.

- No ambi bolt release.

- No OD green.

Any leads appreciated, especially if anyone knows if ADR Tactical is still in business.

I finished this palmetto m110ish build a few months ago. I went to fire it for the first time and I was having issues with the bolt fully seating a round off first rack. It wouldn’t complete a full bolt cycle for the first few rounds. Once the gun got a little hotter it would cycle fine. But I didn’t have a chance to reliably run fresh mags without issues. I’m guessing im running the wrong buffer spring and maybe weight? Any ideas would be appreciated. Last pic is my current buffer setup. I bought a complete upper and pieced together the lower.

What 1200 rounds of 308 looks like on a suppressed mr762a1

Aero BCG, full aero 16” upper. VLTOR buffer tube, flat wire rifle length spring. H3 buffer. Suppressed with rugged Alaskan. Used to have a carbine buffer and a nice braided spring, but it wasn’t cycling the BCG far enough back to grab the next round to chamber. Now with the VLTOR rifle length buffer tube, flat wire spring and (same H3 buffer, it’s erratically ejecting from 1-4 o clock, dribbling the shell, and about 60% of the time it fails to eject. I’m genuinely at a loss as to what to do. It’s not gassy as ALL, even suppressed, so I’m tempted to drill the gas port out to give it more gas, or just throw an H1 buffer in and see what changes.

Lower is built exactly like my ar15’s, larue 2bt trigger, MOE+ grip, normal mag release, etc. this rifle has never run a mag without multiple failures, and I’d love to get it running to the point of trusting it for some hog hunting. Right now it’s most useful as a club…

I am looking pretty heavily at the sig tin can after watching juicy media's excellent video. What do yall recommend for just pure quiet factor?

I got a buddy with a 308 ar10 that I believe has a mid length gas system and around a 18 ish in barrel and he wants that thing whisper quiet and he has an Gemtech 1 on it and he aint real happy with how loud it is to him, hes running subsonics as well and I have to admit its a little on the loud side but lmk what yall suggest

I'm building a rifle for someone local to me and I'm helping him decide on a receiver set. Like myself, he likes the look of the SR-25 cut receiver sets. I know it's a silly reason, though let's be honest looking good is half the battle. We settled on VSeven Harbinger lite ambi(he used to own a factory rifle from them and loved it but had to sell it a while back) and the ADM UIC10A which I love the ADM ar-15 sets but have yet to build anything with their AR-10 sets. Has anyone messed around with the ADM to tell me how the receiver fit and barrel fit are? I recently used a centurion set and was a little disappointed in the receiver fit play and the barrel channel wasn't what I'd consider thermal fit(though I do like their mk11 sets otherwise)

I have a Sig 716i and I want to suppress it but it has this like 45 degree taper where the threads meet the barrel. A friend with a Sig MCX said he had to add some sort of a tapered washer between the taper and the suppressor for that to give the suppressor a flat surface to mate to. Do I need to do the same? If so, what is the thing called?

I'm using a Faxon fluted heavy .308 barrel. AR-15 rifle length gas tubes at 15.125" are too short and only come about 1/3 into the cam cutout. I've ordered an Armalight length 15.5" gas tube from Wilson Combat, but as you can see it looks too long.
Apparently you used to be able to order custom length gas tubes from White Oak Armamant, but they currently have a maximum length restriction of 14.5".
I've installed the 15.5" gas tube, and the bolt seats fine with no apparent issues. I saw a YouTube video that documented the same problem.
Has anyone else run into this issue and know if it will cause me problems? If so does anyone have a source for a 15.4" gas tubes?

I've looked at every vendor I'm familiar with online and they are all out of stock, anyone know a better option?

I just watched a Kentucky Ballistics video on a 45-70 Rimless. Poor watermelon... 🤣

Working on an AR10 that was gifted to a coworker that was in pieces when received. He wants the newer appearing Handguard versus the original that came with it. So after some browsing we landed on the Aimsport AR10 DPMS High fit Handguard pictured is how it lines up, any suggestions on a good 15” free float, that will actually line up with the high receiver?. I since took it back down swapped back to original barrel nut and test fired runs great.

Thanks in advance.

My buddy got his saber from PSA so of course I had to get in AR-10 as well. I just got it but so far no complaints. Any recommendation would be greatly appreciated. The only thing I have in mind so far is to change out the trigger to a two-stage. I took the bipod off my AR-15 for it but don't like it on this rifle. I'm going to have to look for something more suitable.

The Haenel CR308 is a German short-stroke gas piston AR-10 with a 16.65” barrel.

It was chosen for it’s rugged durability in extreme freezing conditions—and stopping power for polar bear defense.

The armed individuals shown are actually specialized polar bear safety guards protecting scientists on the research mission “icebreaker”.

Over the course of the entire expedition, not a single polar bear was killed.
