TacFire 308 Win 7" Complete Upper Receiver with BCG

Seven inches of 308 barrel is a specialist choice, and this upper exists for people who already know why they want it. The bolt carrier group is in the box, so it drops onto a DPMS or LR-308 lower and the build is done. The barrel is nitride treated for corrosion resistance, and an M-LOK handguard free floats it while leaving room for a light or a hand stop.

Understand the tradeoff. A 308 case burning behind a 7" barrel dumps a lot of unburned powder at the muzzle, so expect serious flash and blast and velocity closer to a pistol cartridge than a rifle one. What you get back is a package short enough to live in a bag or a vehicle, and a host that stays compact with a can on the front. This is a pistol or registered short barrel length upper, not a 16" rifle configuration.
