Well, I wasn't patient enough with the OD Greeen Alumahyde cure time and marred the finish while handling it, so I stripped it back down to anodized and just went OD green with the furniture for now.

All put together, just waiting on a PA SLx 3-18x50.  I stuck a Swampfox Trihawk and Justice on it in the meantime, and not super happy with the tape switch, needs about an inch more pic rail to be solid, making me wish I got the Atlas R instead of the Atlas S.

Everything that looks FDE in the pictures is actually OD green, by the way, including the sling and the entire shooting mat.  My S21 Ultra apparently can't see OD.





Aero M5 CMV 18" Atlas S-One complete upper.
Aero Phosphate BCG
Aero Enhanced carbine tube
Aero Breach large charging handle
Broken Arms Armory 6061 billet lower(great fit to the M5 upper, very well machined, comes with tensioning screw and threaded bolt catch too).  I electro-etched the magwells.
Aero M5 LPK
JP H2 SCSS
BCM Mod 1 stock (holding out for a PRS Lite)
Magpul K2+ grip
LaRue MBT-2S SB trigger
Radian Talon ambi safety.
Phase 5 v3 EBR
Slate Black Grip (OD)
Slate Black rail panels (OD)
UTG Recon 360 bipod
SilencerCo ASR three prong flash hider
SilencerCo ASR blast deflector
OLight Odin on Arisaka cantilever mount.
Magpul MS1 sling


I've got a Superlative .750 set-screw bleed-off gas block and rifle tube (and SLR .750 dimple jig), holding off to see how the stock gas block does, might save that Superlative for another build.

Had trouble finding the answer here.

Does the Knight's URX4 fit the Aero upper with no fitting required?

@RJeff21 has one on his.  I bought one to put on mine but still waiting on the Criterion barrel to come in stock to assemble it all.  Just have to make sure you get the SR25 version and you have an M5 NOT the M5E1 Aero upper

The KAC Mk11/SR25 fits Aero upper receivers just fine.

An educated guess says that the URX series will as well as i've seen nothing that suggests that KAK changed the pattern between the older handguards and the newer series.

Yep, URX 4 fits fine.  Just a bit of a pain installing the gas block/tube after the handguard is installed.

Does your urx4 rail have about a .010 height mismatch with the M5 upper?

Kind of. The Aero has a higher receiver height than the URX4 rail by about 1/16-1/8".

It's noticeable if you look for it.

Built a new upper this week.  There was an issue with my 18" S-One upper, the factory installed barrel nut was jammed on the barrel index pin (Aero took care of me, replacement complete 18" upper is en-route).  

But while waiting to hear back from Aero on warranty status, I bought a new Texas edition upper from SpiceTac and sourced a used S-One rail here on the EE, and Brownells had 16" Faxon Big Gunner barrels in stock, so voila!  New complete upper.

Very pleased with how much handier the 16" semi-pencil barrel makes this thing, compared to the weight of the 18" on my other upper.  25oz lighter.



New Aero M5 Texas upper
Aero Atlas S-One 15" handguard (used from EE)
Faxon 16" Big Gunner .308 barrel
SA bleed-off AGB
Aero nitride gas tube
Aero phosphate BCG
SilencerCo ASR flash hider
Slate Black Industries VFG and rail panels
Primary Arms GLx 4-16 DMR HUD
Aero SPR mount
Swampfox Justice on a Valhalla Tactical offset for the Aero mount
Aero "Greenodized" (or ODized? Anyway, prolly too green) Breach large charging handle.

I reckon this also means I need a new BCG, lower, and optics for the warranty replacement 18" upper when it arrives, doesn't it?

to be fair in the comparison, I'll bet your Aero 18" upper has the BA Heavy Barrel  barrel.  not known for being svelte.  so, HBAR vs Pencil... which one is lighter?  I have the Faxon 16" Big Gunner also, in 308.  Yes, I'm surprised with how light it is.  It's lighter than either of my two 14.5" 308 barreled uppers (Criterion & BA).

Did some reconfiguring, and added another M5-based build to the collection:

Top is a Texas Edition M5 upper with 16" .308 Faxon Big Gunner barrel, SilencerCo ASR flash hider, SA set-screw gas block (and I dimpled), Atlas S-One 15" handguard, Aero phosphate BCG, Aero large Breach CH, Radian Talon safety, Aero enhanced carbine tube, JP SCSS H2, MBT-2S trigger, MFT stock, JMT Carbon80 lower, Phase 5 EBRv3, Aero LPK, K2+ grip, Slate Black Industries rail covers and VG, Magpul MS1 sling and rocking an Olight Odin Mini. Optic is a Swampfox Arrowhead 1-10 red BDC in an Aero SPR mount. Built this one from the ground up from parts.

Bottom is an M5E1 with 22" Wilson Combat Super Sniper barrel in 6.5CM, VG6 Epsilon brake, SA set-screw gas block, Geissele Super ambi CH that I bought as a set from the EE, then added a Wilson Combat nitride BCG (which other than logo is identical to the Aero BCGs!), Broken Arms Armory 80% lower (matches M5 uppers damn near perfectly), Radian Talon selector, Phase 5 EBRv3, Phase 5 mag release button, Aero LPK, MBT-2S trigger, UBR 2.0 stock, Wilson Combat grip and rail covers, Atlas PRS bipod.  Optic is a Primary Arms GLx 4-16 ACSS DMR-HUD, also on an Aero SPR mount, but with a Valhalla Tactical offset mount and Swampfox Justice RDS just for shits and giggles.

I tried Aero's 12" rail on my 12.5" build and it would not allow my OSS muzzle brake to mount with enough room for the suppressor to screw on, so I went with SLR.  They offer MIL/LE/GOV discounts and make super high quality stuff and their 11.7" MLOK was the perfect solution for me...

Deadshot Barrels. Built to your specs. I personally don't get along with the guy, but they're good barrels. Lothar Walther are the only blanks in stock, takes 2 - 3 months. Send in your stripped bolt to ensure headspace, or make sure your bolt has a standard DPMS lug length and counter-bore and take your chances. Specify gas port size in the comments if wanted. I would E-mail for verification before buying.

Considering that’s in a recessed part of that carrier and there’s nothing that should/could be coming into contact with it there, they don’t look like scratches to me.  Looks more like lube or something that has run back and dried.  Have you tried giving it a scrub with a brush?

The Aero rifle length action system is fine. Some have issues with the Aero carbine length action, but there are a lot of variables on whether it will work for you. There's nothing wrong with Aero quality, I just use different set-ups.

this topics interests me.  Seems so easy on the 5.56 platform but I tend to get confused on the 308.

My almost-all-aero M5 is super heavy on recoil.  I have the carbine buffer kit.  I intend to install an AGB b/c I'll be suppressing it.  In the meantime, I'm definitely thinking a new spring/buffer combo might help but I don't know what to try.  Is 5.3 oz sort of the T2  buffer of .308 builds?  Is there a go-to spring that everyone raves about?

Is there a way to search a specific thread like this one for specific questions?

I have some questions about two BA/ Aero AR10 builds below.  I have the items below currently.

(2) sets of BA/ Aero stripped lowers.
(1) BA/Aero upper
BA 12.5in 308 barrel
BA 16in 308 barrel
(2) Rubber City Armory BCG’s.
One adjustable SLR GB.

I won’t need an adjustable GB with the 16in barrel?
I will need an adjustable GB with the 12.5 or can I tune it with the buffer and spring?  Both rifles will be using the A5 buffer system.
Do I have to use the Aero pivot and take down pins or can I use the KNS pins?
I will need an extended or longer than normal magazine release button?
I know 308’s can break bolt catches.  Is there one that everyone has better luck with?
Does anyone know if the FCD 7.62 large top paddle bolt catch will work with the Aero upper?
The 16in rifle will most likely get an Aero handguard.
I’m wanting to use a Centurion HG with the 12.5.  Any issues running a Centurion HG on an Aero upper?

Any feedback will be greatly appreciated.  I have put off putting together an AR10 for too long and would like to finish these up soon.

The AR10 16" is pretty stout... an adj. gas block, which may or may not be needed for your specific build, will help you tune it to where recoil impulse is minimal but still functional. The cost really isn't that much considering.

I've not read about broken bolt catches in a while, years ago when the M5 builds started they were breaking with regularity... I broke at least three. I replaced all mine with the DMPS LR-308 bolt catch from Brownell's but I believe they are no longer available. I think current bolt catch assemblies from Aero are ok... maybe someone can chime in with updated experiences.

For the HG, you will need the DMPS HIGH.

The standard supplied mag button works, but there is an extended one available with a longer shank.

you do need to use the Aero M5 pivot, takedown pins.  They are proprietary.  Even the DPMS LR-308 pivot, takedown pins are a tad short for the Aero M5 application.

for the mag release, you have essentially 2 choices:
- use the AR-15 std mag release with the tall Aero M5 mag release button, or
- use the LR-308 mag catch (it has a longer threaded stud) with a regular AR-15 mag release button.

as mentioned above, KAK Industries sells a version of the LR-308 mag catch, otherwise the original DPMS LR-308 mag catches are impossible to find, especially post-bankruptcy.

are gas block set screws all the same measurement apart?  my Aero has set screw low profile GB, wanting to replace with a Superlative adjustable GB.  Wondering if they're all "created equal".  Thanks.

They isn't a standard spacing. For 1" long lo-pro blocks, there are 5 different spacings. The good news is that all the AP blocks I've seen are 0.500" center to center, same as the SA AGB. A lot of Aero barrels are not dimpled though.
