I wanted to build a .223/5.56 rifle capable of 1 MOA (100 yds) to 2 MOA (500 yards) for target shooting, varmint hunting, etc. The rifle is intended to be used mostly in the prone position and with optics only. I acquired the barrel a couple of years ago when LaRue Tactical was having a sale, so the build has bee evolving since. Lastly, I was inspired by Eurodriver's high wind shooting treatise as goal for the rifle (and the shooter).
Here are the specs:
Upper
• 18” LaRue Stealth SS barrel, mid-length gas system, Wylde chamber, 1:8 twist
• SureFire MB556K muzzle brake
• LaRue low profile gas block
• Geissele Mk 4 15” hand guard
• Vltor MUR upper receiver
• BCM bolt carrier group
• BCM Gunfighter Mod 4 charging handle
Lower
• Battle Arms Development forged lower
• BCM lower parts except for Battle Arms Development ambi selector and takedown pins
• LaRue MBT 2 stage trigger
• A5H2 buffer and Sprinco green action spring
• Magpul UBR G2 stock and A5/SR25 Receiver Extension
Accessories
• Nightforce SHV F1 4x14x50 Mil-R scope with LaRue SPR mount
• Harris bi-pod
I've got close to 1000 rounds through it so far, and it has been 100% reliable, running in temperature ranges between 23 degrees and 105 degrees. I've achieved 1.25 MOA at 100 yards and am consistently able (80%ish) to hit an 8" steel gong at 500 yards, in moderate wind, like 25 mph cross winds. A little better with light wind.
