The Build Story
Two roles, one rifle
.300 Blackout at 16.5” covers ground most rifles have to choose between. Supersonic loads give you legitimate stopping power at general-purpose carbine distances. Subsonic loads behind a suppressor turn the same rifle into a quiet, controllable platform for confined spaces or work that doesn’t announce itself. The adjustable gas block runs clean on both; we dial it in before it ships.
Trijicon ACOG, built for the round
A 4x32 ACOG with a .300 Blackout BDC reticle means your holdovers are real at every distance in the effective range band. No guessing, no mental math; the reticle is engineered for the cartridge. Suppressor-ready threading at 5/8x24 means a can threads straight on without an adapter. Every component is installed and zeroed as a system before the rifle leaves the shop.
Engineered as one system, proven before it ships
Every build is hand-assembled, torqued to spec, and function-tested both supersonic and suppressed before delivery. This is the platform for the shooter who wants .300 Blackout’s full versatility in a rifle-length setup, built end-to-end, not assembled from a shopping cart.
