I realized today that I never posted a picture of the completed build. This started here with my thread back in 2022:
https://sigforum.com/eve/forum...540061094#8540061094

Here's what went into the build:
-- CMMG Mk3 stripped lower DPMS Gen 1 High Profile
-- CMMG Gunbuilder lower parts kit Mk3
-- Hiperfire EDT Designated Marksman Trigger (4.5lb spring)
-- Aero Precision M5 18" CMV Ballistic Advantage barrelled upper w/ Atlas R-One handguard
-- Aero Precision M5 .308 Carbine Buffer Kit
-- PSA P10 .308 Nitride Bolt Carrier Group
-- Strike Industries AR-10 Charging Handle
-- Votex Strike Eagle 1-8x24 Gen2 w/AR-BDC3 reticle & 30mm cantilever mount
-- Magpul ACS Carbine stock
-- Magpul M4 MOE K2 Grip
-- Magpul M3 10 and 30 round PMAGs
-- LANTAC Dragon Muzzle brake (Karma from Oat_Action_Man ... thanks Patrick!)
-- Harris M-Loc bipod/sling adapter
-- Harris Model H 13.5-23” bipod

Only hiccup we had was that the takedown pin hole in the Aero upper was tad undersized.

How's it shoot? How did Aero deal with the oversize pin hole? Your mount is backwards.

Nice bald1, congrats. What do you have into it. less optic and mount?

For someone interested in a AR10 on a budget check out PSA. You can pick one up at some incredible deals right now. Even one with a Gieselle trigger.

Yep.
Although it's been awhile since I've used a Harris bipod, I suspect it's on backwards, too.

TOUGH CROWD!

First the takedown pin hole required some minor polishing to reem it to the correct size. Aero wasn't contacted as this issue is said to be somewhat common for such builds with differing manufacturers of uppers and lowers.

Second, the Vortex mount was originally much further back and mounted this way to provide extra clearance for my hand to grab the small latch wings on the charging handle. (As an aside in hindsight one with a much larger latch like the Vitor (BCM) AR10 / SR25 Mod3 would have been a better choice.) The mount was slid forward for my son who is a half foot taller with a much longer LOP and differing eye relief preferences. The scope is very light and quite secure / functional as is.

Third, the Harris bipod is mounted so that it folds under the handguard rather than sticking way out in front of the muzzle when folded. Wanted the bipod height to allow the use of a 30x PMAG. Also have on hand the Harris Model L (9-13") that could also be used. The rifle is heavy and with the Lantac brake shoots very soft with zilch movement so the bipod function hasn't been as issue as mounted (no collapse on recoil). Pre-loading the bipod is pulling the stock backwards into the shoulder.
