The Battle Arms Xiphos is a 9mm AR-style pistol caliber carbine built on a billet BAD-GS 7075-T6 aluminum receiver with a free-float M-LOK handguard. This 16-inch model runs a blowback action, pairing a 4150 chrome-moly barrel with an 8620 steel bolt finished in black nitride, and the rifle itself ships in gray. It uses a dedicated 9mm buffer system to cut felt recoil and wear over standard AR buffers.

Owners of the Xiphos generally point to the billet receiver and chrome-moly barrel as the reason it holds up under heavy range use. The black nitride bolt is easy to strip and clean, and the blowback action is simple mechanically, which owners like when something in a PCC needs fixing at home rather than sent back to a shop. A few note that any blowback 9mm carbine runs its bolt harder than a locking-breech design, so buffer springs and bolts are treated as wear items.

The ambidextrous charging handle and adjustable pistol grip get called out often, since a PCC built off the AR pattern lives or dies on how familiar the controls feel. The free-float M-LOK handguard has room for a light or a brace of rail accessories without crowding the barrel. Recoil impulse is the main selling point people mention, softer than a rifle-caliber AR and easy to run one-handed.

On value, the Xiphos sits above entry-level PCCs, and owners weigh that against the billet construction and the enhanced small parts included from the factory. Aftermarket AR furniture and optics drop on without much fuss since the upper and lower follow standard AR ergonomics even though the internals are PCC-specific.
