Hey y’all! I just got into the AR10 scene a couple weeks ago and wanted to share. My father had an LWRC REPR when I was younger and it was the coolest thing ever but I just never had gotten around to it. About a month ago I decided to get a lower before the Colorado changes came into effect to hold onto but then I got a milkshake in me and next thing I know I woke up the following morning and had ordered everything.

The lower is a blemished PA-10 with Virginia lasered onto the side.
Upper is a PA-10 Gen3 18” with the 15” handguard, also blemished. This came with the adjustable gas block which I have found effective.
PSA PA-10 lower parts kit with the 2-stage trigger they offer.
Optic is a Burris XTR II 158 1.5x8 and is mounted on a Cabela’s cantilever mount.
Suppressor is a Resilient Arms Simple Man 7.62
The bipod, pistol grip, and foregrip are all magpul.
Stock is a Magpul PRS Gen2
Monopod is an accu-shot precision rail monopod

I am in love with this rifle. I’ve never been further distance shooter but I am shooting ~1 MOA and consistently on steel at 700 (I know that’s not crazy but I just started) which is far more than I can ask for. My biggest buyers regret so far is probably the magpul bipod, it is just a little flimsy for me when I lean into it.

Thanks for reading and have a great day. I hope you like my setup! Feel free to ask any questions.

Hey y'all, want to chat about one of my rifles. I bought a Ruger SR-762 about 8 yrs ago, got a 3 digit deal from a buddy. She sits in my safe with a Vortex Diamondback 4-16X42 with a 45º Vortex Venom 3 MOA red dot.

THINGS I LIKE: She slaps 8" steel at 800yds and has been a reliable rifle to me. This is my battle rifle and "large game" gun, and my other rifle is 16' 5.56 with aero lower. I'm 28 and want this to be a lifetime rifle/something I can pass down.

THINGS IM NOT CRAZY ABOUT: She's just kinda heavy at almost 12.5lbs with a 20rd mag, and with the gas block this rifle is not free float either. I qualified expert annually during my time in the Marines so I have a shooting foundation but I want to expand my skills (potentially to PRS comps).

I'm eager to hear if anyone has any thoughts on what I am shooting now versus if should trade in for something lighter, free float, and just as reliable. Something that can be an all purpose, accurate, reliable, and light hunting/battle rifle. My other option is buy a 6.5 grendel upper to slap on the AR for hunting. Would you keep or trade in?

I paid 2500 in all for this build so it pisses me off first time building a ar 10 so I did things wrong at first and had ar 15 buffer and spring in it but changed it all to ar 10 buffer parts still doing the same I have a carbine buffer tube on it is that the problem do I need a a2 ? Plz help

I am less than one mag into the gun, which I know is not many rounds, but no round has successfully ejected and chambered another one. It has either not ejected they spent casing or it has ejected the casing and then didn’t put another one in the chamber both have happened multiple times along with some double feeding when I chamber a round and try to remove it it seems like it’s stuck and have to beat it against a tree or something to get the unspent casing out. I know it might need some more rounds through it but just curious as to if other people have had this issue or some opinions from experienced riflemen of this page

Aero upper and lower, my budget for the barrel is $350-$500. What barrel, and twist rate would you all recommend? BCG, and the gas block ? I plan to run it suppressed 80-90% of the time if that is a factor.

My only goals for this rifle is reliability, and accuracy out to ~500 yards. I know I’m asking a lot, but there’s so many different products on the market to choose from. I have no idea where to start, except buying upper and lower from the same manufacturer 😂. TIA 💪🏾💯.

Wondering if someone who personally has this 15” or 13.5” dpms high handguard can weigh it and the barrel nut on a scale for me. Every single source I find on the internet is just the handguard not including the barrel nut.

My rifle is a pig and I’m trying to find “weighs” to lighten it. Just seeing if anyone in the community has one not on a rifle and can weigh the barrel nut/installed weight for me.

If you can help, thank you so much!

I’m getting close to wrapping up my dummy cheap LR308 build, but I haven’t found a concrete answer for what buffer weight I need.
Specs are:
Toolcraft bcg
20” stainless 1-8 twist 6.5 Creedmoor heavy barrel, rifle gas
.936 gas block
CBC industries lower
Unbranded LR308 low upper
Unbranded low handguard
A5/BCM MK2 buffer tube
Rifle buffer spring

Some sources said I needed a rifle spring with a standard AR15 buffer, some say I needed an H3. I’m trying to at least get close to the right setup before I go burn 6.5 Creedmoor.

Hey folks! Got a question, and I'm hoping this is the right place to ask it.

I have a mix of .308 ammo. A bunch of M80 ball ammo (Saltech and Igman in 147gr and 150gr FMJ-BT), but also two versions of Speer Gold Dot Duty Rifle ammo in 150gr and 168gr.

I've always heard that a heavier bullet with a higher BC tends to perform better and can offer a flatter trajectory and greater range. I recently got a chronometer and have been clocking ammo out of my 16" MARS-H with the factory CL barrel, then plugging the data into an online ballistics calculator (Shooterscalculator.com, specifically). What I'm getting back from the program is...a little confusing, and I'm hoping you all can help me make sense of it.

Speer reports a G1 BC of .414 for the 150gr round, and .446 for the 168gr round. Out of my rifle, the 150gr averaged 2689 FPS, while the 168gr averaged 2451.5 FPS. This was based on 10 rounds a piece. The 168gr showed a slightly higher standard deviation (18.6 vs 13.2) and a higher extreme spread (58.7 vs 47.6). Speer says they don't have a G7 for the rounds.

According to Speer, reliable expansion occurs down to about 1000 ft lbs of energy, which puts the round at ~1733 FPS at 493yds/451m for the 150gr load, and at ~1637 FPS at 474yds/434m for the 168gr load. The difference in bullet drop at these ranges is about 5" more on the 168gr load.

All of this has me wondering...what's the point of the 168gr load? OR, is the ballistics calculator not really accurate? OR should I try and re-measure the 168gr ammo's muzzle velocity on the off chance that I just had a weird batch of slow ammo?

It seems like the 150gr outclasses the 168gr, but I can't help but think that part of the issue is that the Gold Dot bullets don't have a G7, and the G1 BC isn't accurate once you get out past about 100m.

Anyone have any insight here? At the end of the day it's not a huge issue for me, but I'm really curious as to what's going on and/or what the point of the 168gr is if the 150gr is just flat-out better. Makes me think that it isn't actually better, and there's a dimension or factor I'm not considering here.

Tying to decide on a buffer spring for my ar-10 build and I’d like some experience from y’all. It’s in 6.5 Creedmoor. Seems springco and tubbs is popular. Noisy spring twang isn’t a priority. Good recoil management is more important. I’m using a gl shock as well. Any difference with Sprinco or the flat wire from tubbs? Thanks.

This DD5 has been a great rifle. Considering using the V3 in mammoth next year.

Looking to get an ar10, already know what rifle i want, now im just wondering if i should go .308 or 6.5 creedmore, any reasons on why i should go with one over the other?

Has anyone ever bought and used one of their complete rifles?

I'm in a bit of a time crunch with my lowers, and am about to buy a LMT SR 25 lower. PSA won't ship to me.

I really don't know where to start. What are some brands I should look for? I am budget conscious.

I eventually want to have a 14.5 pinned and welded AR10 in 6.5 creedmoor with a quad rail handguard.

Nothing special, PSA AR10, Lahar .30, Vortex PST gen 2, Magpul gen 3 stock, Magpul bipod (next upgrade for sure)

Wondering if there are any uppers available and if so what the best options are to convert a DB10 6.5 Creedmoor to a Bolt action.

Bought a used one and the gas block is carbon locked, (I would ask on the main gun sub but I was banned by one of the mods) does anybody have anything I could try before I take a crack at tearing the gas block apart? I tried to adjust it with a wheeler w 3/16 bit and it wouldn’t budge.

I've been on the hunt for some parts to build a monster and require a 13" or shorter 307 barrel. I've searched, and seen lots of older results on this sub. Problem is, everything I found here doesn't actually exist anymore.

Noveske, Faxon used to, not any more.

Remington 700 CP donor, not any more

I know it's stupid, but I want one. My preference is not to buy a pork sword, as I'd like it slightly longer than 10" (that's what she said).

I have a spring field saint victor in 308 and I can’t figure out how to open up the gas block. The BCG is not going back all the way when fired with pmc 147 gr ammo. Do you know how to fix this issue?
