jdurzuaI’m testing the waters on selling this brand new 10.3 upper. It currently has a Q cherry bomb muzzle device, KSPEC downward venting double ejector BCG, and raptor SD charging handle. It will come with a griffin maritime buffer tube, spring, suppressor a2 buffer, and BCM sopmod mod 2 stock. This upper has had 60 suppressed rounds and 60 unsuppressed to check function. It fires fantastic and almost zero gas back to the face. 2707483858
