The heart of this rifle is the 18-inch Rainier Arms 416R stainless UltraMatch MOD 2 barrel. Its fluted profile trims weight while the 1:8 twist stabilizes the full range of 6.5 Grendel bullet weights. A Rugged Suppressors 7.62 three-port muzzle brake, threaded 5/8-24, tames recoil and is ready for Dual-Taper-Lock suppressor mounting.
Radian’s lower features the patented A-DAC mechanism, allowing the shooter to lock the bolt to the rear using the right-side magazine release—speeding malfunction clearance and administrative handling. An ambidextrous safety selector, ambi mag release, and Aero Precision Breach ambi charging handle round out the fully bilateral control set.
The trigger group is a TriggerTech Duty two-stage flat-faced unit set at a crisp 3.5-pound break, paired with a JP Silent Captured Spring recoil system for smooth cycling and minimal spring noise. An Odin Works 6.5 Grendel bolt carrier and Grendel Hunter complete bolt ensure proper headspace and reliable extraction.
Outside, the rifle wears a Midwest Industries 12.65-inch Combat Rail T-Series handguard that offers full-length M-LOK attachment and comfortable ergonomics. The Magpul PRS Lite stock, finished to match the receivers and rail, provides adjustable comb height and a 14.0-inch length of pull to fine-tune fit for precision shooting.
