Superlative Arms bleed-off.  

I set it up to use the bleed-off function at first, but after going back and forth a few times, I ended up using it on a restricted setting like a normal AGB.

Buffer is a standard weight JP SCS.

So std weight buffer?

So how does it run?

On say normal 147/150 gr fmj ball?

Is it a bruiser or not bad ?

Yeah, standard weight SCS works fine as long as you’ve got adjustable gas. The heavy version won’t give you any issues, though. You’ll just need to give it another click or two on the gas block.

Runs perfect.  Cheap shit, steel, reloads, doesn’t matter.  With decent ammo, it’s actually good out to 300+ yards. Maybe more if I put some magnification on it.

There’s more recoil than a small frame gun, but my 110lb girlfriend is able to fire it comfortably from the shoulder, so it’s not unbearable.

So here is what I have for ar-10 build

Aero complete lower
Aero m5e1 upper minus barrel (has brl nut no shims)
Aero .308 CMV BRL Rifle L. (18inch)
Aero enhanced handguard
Aero gas block
Aero S.S. rifle length gas tube
Aero BCG
Surefire muzzle break for socom (has some shim's/ no crush washer)

Do I need a crush washer?

I either need to find a charging handle local or order one....

Anything else I need in order to put this together?

Do not use a crush washer if you plan on attaching a suppressor.

That's what the shims are for.

Even then, use the shims.  They take a little bit more time/effort than a crush washer but they are just as sturdy and come with the side benefit of being better for alignment.

This way when the suppressor bug gets you, you won't have to remove and re-mount your muzzle device.

When you take them out of the package, you’ll be able to feel (or use a set of calipers) to determine the various thickness of each one.

Different combinations will align or “time” the ports on the brake in different positions.

You want them to be around 10-11:00 hand tight, then hit it with rocksett/loctite and a torque wrench until the ports are aligned where you want them.

Yes. When it does chamber a round it won’t eject it. It’s stuck  tight. Only way to get ejected is to hit the charging handle with rubber hammer. Have never fired this rifle because it wouldn’t cycle. Sometimes ejector will let go with round in camber but then jams when it attempts to strip next round from mag.

IIRC the DD Lite 762 was the Original DPMS "high" .210 tang height.

Meaning yes, it will fit flush to Aero.

I’m dipping my toes into the AR-308 game. I started looking at Sig 716i’s and the POF DI options, but proprietary parts (for which replacements are often unobtainium) scared me away. Decided to do an M5 build instead.

Can anyone confirm these parts will play well together? Based on my reading they should but thought I’d ask before I started ordering parts

M5 stripped upper & lower
Toolcraft double-ejector BCG
MI combat rail, DPMS high
Criterion 16” M118LR barrel
Adj gas block of some sort (I prefer the Aero AGB but nowhere to be found atm)

I’ve also seen where it is advisable to use the Aero LPK with the M5 receiver but I’m unsure about the trigger. Will a standard AR15 trigger of my choice work? Or do I need to look for certain triggers?

TIA

Your parts look good to me.  I have a Geissele SSA-E in my M5 build.  I think the LPK thing comes because some of the parts screw in rather than hammer them in (bolt release I think is one of them).

I would stick with the Aero LPK. It includes the threaded bolt catch pin, tensioning screw and takedown detent/spring 4-40 set screw. I've bought a few of them with the FCG and they've had a Schmid FCG, which is one of the better spec triggers. Its worth the extra ~$20 even if its just a spare. Most, if not all, FCGs will work. Aero had some early problems with broken bolt catches, but I've not heard of anything lately with a properly built firearm. I would still keep a spare around. I've used Aero and Superlative AGB's without problems. The Aero is one of the best looking AGB I've seen but it does have an open body which will show the gas block journal if its unfinished or polished. Sharps Rifle Company makes a nice 308 BCG but they've had some financial problems in the last year or so which I hope doesn't affect the lifetime warranty. Pay attention to your buffer set-up, a lot of problems originate there. Good luck!

Edit to add
I would also recommend buying a spare firing pin at the same time you get your BCG. There are a number of different firing pin diameters and they are not interchangeable.

Thanks for the info. The Toolcraft BCG I'm looking at states that it has a narrower (.065") firing pin and channel. I'll try to see if I can find a spare separately. As far as the gas block, I like the Aero because it is one of the less-bulky (for lack of a better term) AGB, and with a 16" rifle gas barrel and 15" rail, it should be pretty easy to adjust from the front. For the buffer, I was planning on just getting an Aero .308 buffer/tube kit and use the AGB to tune any issues. Are there other buffers I should be looking at?

I plan to run this rifle suppressed 99% of the time and meant to ask about the PRI .308 gas buster CH, but I see it was a confirmed fit a few posts above.

thanks again for the info.

The Aero carbine buffer is 3.8oz, which I feel is too light. I believe that Aero chose this weight to help with the bolt catch issue. If I'm building with the standard length AR15/308 carbine receiver extension, I use the ~5.5oz buffer weight. You can buy tungsten weights and swap the steel ones out yourself. A lot of builders prefer the Armalite AR10 RE/buffer/spring kit which is compatible with the your DPMS build. It is the same as a A5 RE. Forward Controls also offers a nice A5 length RE and then you just buy the appropriate A5 action spring/buffer. I feel that running suppressed would be much better with the A5 or Armalite set-up.

I use the SLR Sentry adj GB with my Aero M5 builds (308 & 6.5CM), adjustable from the front, has click-stop settings.
main reason for getting the Aero LPK is for the non-standard-length take-down pin, pivot pin, and the extra tall mag release button.  rest of the stuff is standard AR-15, although as mentioned, the bolt catch uses the dog-ended set-screw instead of roll pin for retention, seems to be common practice for a lot of AR-308 lowers though.  In my limited experience, standard and aftermarket AR-15 triggers have worked fine in my M5.

The A5 RE is unique in length. As far as I know, they are all mil spec diameter. Make sure your adjustable stock is mil spec and not commercial spec diameter. Keep in mind that the length of A5 RE will not allow your stock to fully collapse as you might be used to with standard carbine REs. The A5 uses rifle length action spring and a unique length buffer, longer than a carbine buffer and shorter than a rifle length.
Tuning the action system usually falls into two schools of thought; spring strength or buffer weight. It would be pretty rare that a strong spring and a heavy buffer weight would be needed. I go with buffer weight because its cheap to swap weights. A lot build specs go into choosing the correct buffer weight. Using an AGB gives you a lot more leeway with your choice. Slash's Heavy Buffers is a great place for info and parts. You can contact him if you have questions but you will need to know all the specifics for your build. Sprinco is good for action springs.
If you ever consider using your firearm 50/50 suppressed/unsuppressed, you might consider a selectable gas block or bolt carrier.
Double check your gas length on that 16". Rifle length gas will give you a pretty short dwell and depending on your gas port diameter, you might not need as much buffer weight as a mid length
or carbine length gas system. Hope this helps.

I decided to just use a standard carbine tube and JP SCS. I ended up with the Criterion barrel because I was specifically looking for 16” with rifle gas and they are one of only a few I found without going custom. I really don’t plan on shooting this unsuppressed so the longer gas system length should have plenty to cycle without beating parts all to hell.

Thanks again for your help and the detailed info.

Built my first couple AR's a few years ago and always wanted an AR-10 for hunting. I started ordering parts for this in November and finished it up last weekend. I had two goals for the build: 1) Keep the build cost under $1k for the rifle, and 2) Shoot 1 MOA or better. All in all, I spent $1059 on the build (I already had the optic, Magpul MOE stock, and one of the members here sent me a free Mil-spec trigger), I'm happy with how it shoots.

Lower:

Aero M5 Lower
Aero M5 LPK - Trigger
Trigger is Mil-spec unit a member here supplied me with
Magpul MOE stock in FDE
Aero Buffer Kit

Upper:

Aero M5 Upper
Ballistic Advantage 20" .308 Modern Series Heavy Profile Barrel
Aero BCG
Radical Firearms Ghost Flash Hider
Strike Industries C/H with Extended Latch
Aero Gas Block
Expo Arms Rifle Length Gas Tube
Samson's New SXS-762 Lightweight 18" Handguard in M-Lok
Magpul FDE M-Lok Rail Covers

Optic:

Primary Arms GLX 20 MOA Scope Mount
Vortex PST 4-16 FFP MRAD Scope

The last picture is a picture of a 3-shot group at 100 yards off the bipod with no rear bag after sighting in. The group is with Hornady's Precision Hunter 178 ELD-X ammo.

I didn't do a 'break-in' procedure on the barrel, and the group was within the first 10 shots the rifle fired. Hoping for better groups as the barrel gets more used

Looking at building a MK11 Mod 0 inspired rifle.  Trying to source the right barrel to work on a AP M5 upper, I have the rail & gas block.  So shifting focus to the lower, I want to use a A2 fixed stock.  Any suggestion or experiance with A2 stock, receiver extension (I have the rifle one from AP) and spacer that is quality & fits?

I just recently caught the AR bug (during COVID lockdown) and have now built 4 ar-15 in the last 6 months. About a month ago I spoke to my nephew about going hog hunting in Texas, But I wanted something with a bit more stopping power than my 2.23/5.56 and more range than my .300BO. Enter the .308 AR10!!

Upper-

Aero Precision M5E1 complete upper - FDE
DEZ Arms 16" FLuted Match Barrel with 1:10 twist
Odin Works Atlas 7 Compensator
Trybe Ambi charging handle
Grid Defense Nickle Boron BCG
15" Presma M-Lok Handguard ( only using until I can get an Aero R-One in FDE)

Lower -

Aero Precision M5 Lower - FDE
CMMG LPK
Timney AR-10 Single Stage Trigger w/4lb pull
Magpul MOE grip - FDE
Aero Precision Carbine .308 buffer kit (heavier buffer and spring on order)
Hogue Overmolded Stock - FDE

Optics -

ATN X-Sight 4K Pro with ABL (laser Range Finder) attachment
Wicked Lights A67IR IR Illuminator

With the optics and loaded, this thing is a BRICK, weighting in at 14.4lbs. Luckily I will not be hiking and/or stalking with this rifle, so the weight is not an issue.
