Well after 10 builds in three different calibers, lessons learned, and advice garnered from the Horde, I present my version of the ultimate AR. I was shooting for 6LBS before optics and ended up at 6LBS 4OZ and weighs in at 8LBS 7OZ with optics and bipod. Very balanced to carry and fire freehand. Only foreseeable change would be changing the optics to the Leupold Mark MOD 1 3-9x40mm FireDot-G TMR Reticle which would get me to under 8LBS, but limit my effectiveness at long range (400 YDS).
She cycles beautifully and has shown good groupings with factory ammo already. Federal Fusion 120GR produced .6 MOA first 3 shot group...we'll see if we can do it again. Will be developing a load with Maker 95GR TREX and H322. Hoping to safely get 2800+ FPS on the 95GR with 1 MOA. Theoretically, this 16" 3R barrel will give velocities of an 18" with copper projectiles...to be tested and proven or debunked.
Build List:
16 inch Grendel with ARP 3R barrel and bolt
Aero Precision M4 upper and lower receiver
Aero Precision 12 inch Atlas S-One handguard
CMC 2.5LB Single Stage Flat Trigger
Toolcraft BCG
Geissele Super 42 Spring and H1 Buffer
Magpul CTR Buttstock
Magpul MOE Pistol Grip
Vortex Diamondback HP 3-12x42 BDC Reticle with Side Focus Parallax
Aero Precision Scope Mount
Vortex Viper Reflex
UTG 45 Reflex Mount
CVLife Carbon Fiber Bipod with M-LOK Swivel Stud
