This isn't a terribly common occurrence but it does happen from time to time. All of a sudden for no apparent reason you can't pull the trigger or move the safety on your AR15. The hammer is stuck in the cocked position and will not move no matter how hard you try to pull the [...]

Sometimes it is necessary to replace the gas key on an AR15 if it becomes damaged or plugged or if a gas key screw is broken. I've seen blown primers get wedged down inside which turns the rifle into a single shot. Most times it is impossible to remove it so replacement of the key [...]
Now and then I get the question "Is my flash hider or muzzle brake removable?" The majority of rifles we build have removable A2 flash hiders but we also build rifles for states that have banned some features of modern sporting rifles. One of the banned features in those states is a flash hider or [...]
First make sure the weapon is unloaded! Then remove the upper from the lower half of the rifle. Using a 1/16" Allen wrench, remove the bolt catch pin. A long straight Allen wrench as pictured is easiest, but you can also use a small L shaped Allen wrench as well. Place the Phase 5 bolt [...]
