Thank you - I just scored my third stripped upper.  I think I'm set for all the builds that I want to put on the lower that I recently assembled.

Also protip if you order from RCA, and don’t care much about mis-lasered logos, order the blem BCGs. They’re usually in stock and if not they are usually no more than a week or two wait, the savings is worth the possible delay.

I'm gonna grab a couple and chop them for a 12.5" barrel (cut rail to 11.5") and 14.5" barrel (cut rail to 13.5") Aero M5 uppers. Your 16" is pretty good for an all-around AR-10/.308 As for the muzzle device, it'll depend on what supressor you end up getting. I like the Surefire 3 prong 7.62  SOCOM flash hiders. It'll be cheaper to just use the Aero M5 upper you have compared to buying a complete new upper assembly

If the usual places such as Arm Or Ally and Primary Arms don't have it, then about the only other place I'm seeing Aero stuff is on GunBroker.

I do have one of their AR10 BCG's and have had no issues with it.

As of now the LPK's, take down pins, and bolt catch are all OOS.

Any one use these BKings ones?

Sgt Of Arms makes M5E1 in a couple of different lengths, with ARCA rails on the bottom...

Also, I replaced my Superlative Arms adjustable gas block with a Riflespeed - single biggest upgrade I think I've made to the rifle. Way easier to adjust the gas, and way easier to switch between suppressed and unsuppressed without needing to dig out a special tool to do it, and count clicks. I'd put the Superlative block up for sale, but I couldn't sell it in good conscious...it's just not good compared to the Riflespeed

I really hate to see Aero in the predicament that they’re in… the M5 seemed to be the go-to DPMS/SR-25 pattern build. I have one complete rifle that I’ve only just run through a function test and another upper that a friend wants to buy.

It sucks but it is what it is…

Finally remembered to take a pic of my 12in SBR. It is a Rainier Arms barrel, and Noveske rail with mostly Aero Parts. It has a Primary Arms 1-10, and an SDN6 that was converted by Ecco Machine. I'm going to try to get a deer with it this year.

My LGS has two M5 stripped threaded uppers for $149 each and one M5 assembled threaded upper for $169.

PM me if you just have to have one and I'll give you their contact information.

M5 “enhanced” with the extra extruded bit where the barrel nut goes, or a “normal” upper?

I happen to have an extra 12” enhanced rail at the moment that might could use a home

Labeled (and priced) as stated - M5 threaded, not M5E1 enhanced.

I still need a buffer/spring, stock, trigger, and handguard.

I’m in the same boat. Need to get off my azz n throw it together. Mines all Aero except the barrel.  Have a WC 18” bull.  After reading the other comments I’m already rethinking it due to weight

Well now I'm really glad I built my green M5 thing in 2024.Attached File
