This conversion kit includes the handguard, muzzle device, and front sight post. The gas tube with op rod and charging handle will come pre-assembled inside the tube. All you would need to do is unscrew the muzzle device, remove the two set screws in the front site, remove the handguard, and install the new parts.
***THIS KIT IS PROPRIETARY TO THE DEAD FOOT ARMS UPPERS.***
