Barrel and Muzzle Device

The 5.5-inch barrel is chambered in 10mm with a black nitride finish and a 1:16 twist rate. The thread pitch is 5/8x24, which matches the included Pershing steel flash can in black. At 5.5 inches this barrel keeps the overall upper compact while covering the front end from muzzle device to upper receiver.

Vertex Upper Receiver and Handguard

The Vertex enhanced billet PCC upper receiver is billet aluminum with a black finish, designed around the pistol caliber carbine platform. The 4.2-inch freefloat tubular M-LOK handguard is aluminum with a suppressor-ready design and a 1.77-inch internal diameter, providing M-LOK attachment points along the tubular body for accessory mounting. These two components define the exterior structure of the upper assembly on this AR-15 PCC platform.

PCC Bolt Assembly and Charging Handle

The PCC bolt assembly is compatible with 10mm and .40 S&W and covers the upper internal components beyond the barrel and handguard. A Mil-Spec AR-15 M4 charging handle is included to complete the upper component set.
