Bootleg Partial Upper .300 BLK

Design

The forged M4 upper receiver, complete with a forward assist and flat top Picatinny rail, guarantees durability and compatibility with various accessories. Attach preferred optics, sights and other accessories with ease.

Attached to the Mil-Spec Partial upper receiver is a high-quality 12.5″ barrel chambered in the versatile .300 BLK. With a 1:8 twist rate, the barrel ensures exceptional accuracy and reliability. The .300 BLK chamber provides a variety of ammunition choices that shoot both supersonic and subsonic rounds with precision and power.

Functionality

For reliable gas operation, the partial upper features a carbine or pistol length gas system connected by the low-profile gas block. This combination optimizes gas flow and cycling, resulting in consistently smooth performance. The upper is completed with an A2 muzzle device. This setup effectively reduces recoil and muzzle rise for improved control and follow-up shots.

Quality

The proprietary CamLok system is a standout feature of the partial upper. This innovative system securely locks the handguard in place, providing stability and controlled movement during intense shooting sessions. The M-Lok attachment slots assist in personalizing a firearm with a wide range of accessories. A full-length Picatinny rail along the top offers even more options for accessory mounting.
