I put together a 308 DMR. Not called that because I ever was, or ever could be, called a Designated Marksman, but because of the desired results I hoped to achieve in the quality, and accuracy of the build.
The parts:
Ascend Armory Match Billet Receiver Set – 7075
Rainier Arms AR10 Switch Keymod Rail .308 – 17”
Rainier Arms Ultramatch Mod2 .308 Barrel .800 Gas Block TiN Extension Fluted – 18”
Rainier Arms Adjustable Bas Block Solid Bleed Off .800 Black
I asked Rainier to pin the gas block for me – I do not have a jig for that.
SI UDC Ultimate Dust Cover for .308
Rainier Arms .308 NiB BCG DPMS SR-25 Pattern
Geissele Super Charging Handle
CMC AR-15/AR10 Lantac E-CT1 Single Stage Upgrade Trigger – Curved
Ascend Armory Titanium 50 Degree Short Throw Ambi-Safety
LUTH-AR .308 Rifle Length Buffer Tube Kit (includes Rifle Length Spring and Rifle Buffer)
MagPul PRS Gen3 Stock
BCM Gunfighter Grip Mod-1
AAC Blackout 51T Flash Hider / Suppressor Mount (for use with the 762-SD)
I pulled a Leupold 6.5x20 AO Target scope off an existing build for this rifle.
I selected the CMC Curved Trigger because currently I do not have a flat trigger. I may get one in the future and drop it into one of the guns with a “mil-spec” just to see if I like it. But I wanted to build this DMR with a fire-control setup I am very comfortable with, and that means a curved trigger.
I selected the Ascend Armory Receiver Set because of certain unique features and controls. It is an ambidextrous lower receiver, and they have stated they will upgrade the lower (for free) with their ambi-mag release when it is available. The matched set also looks good.
The barrel was selected because I have other Rainier Ultramatch barrels and I am extremely pleased with their accuracy off the bench. For their Ultramatch series they use Shilen blanks. If a rifle is accurate off the bench, it will be accurate in the field – in the hands of a rifleman (apologies to the many ladies that are excellent shooters). The barrel has a “.308 Rainier Match Chamber”. Quote from the Rainier web site:
“The Rainier Match Chamber is a modified .308 WIN-7.62 NATO chamber to produce ultimate reliability and accuracy shooting both the 7.62 NATO & .308 WIN rounds.”
It is (extremely) unlikely that I will ever hump a DMR in the boonies with a spotter and kit, but as Townsend Whelen once said, “Only accurate rifles are interesting.”
I thought about putting another BattleComp 51.30 on this build, but I had a never used AAC 308 mount in the parts box. SilencerCo shipped it with the 762-SD and I did not know it was a package deal, so I bought a mount when I bought the can. My loss then, my gain now.
