Where to start
The shop is organised around the build rather than the catalogue. The higher you begin, the less is left for you to reconcile.
One shop answerable for the configuration, the assembly and every interface between them.
Browse rifles
Where the art of the rifle lives. Barrel, gas system, rail, sights and muzzle device, solved together.
Browse uppers
The heart of the gun. Profile, length, twist, gas system and muzzle interface decide what a build can honestly be.
Browse barrels

The can has to agree with the barrel, muzzle device and collar. NFA transfer applies, so start early.
Browse suppressors
Read first, buy later
If you would rather understand the platform before spending anything, start here. Each hub lays out the variants, the era markers and the parts that have to agree.
Clone-correct is not a category we entered. It is the only thing we do. We hold direct relationships with SureFire, LMT, Nightforce, Cadex, Geissele, Daniel Defense, Leupold, Allen Engineering, A.R.M.S. and Douglas, plus mil and LE distributor status with Colt and HUXWRX.
When a correct part cannot be bought, our sister company Potomac Armory makes it to the specification rather than to a photograph. Few shops cut M110, Mk12 and Mk11 barrels at all. We cut all three.
