Saves The Frame & Your Thumb When Tuning AR-15 Triggers

movement and pull weight without sacrificing your thumb. Go

hammer from striking the wall of the magazine well. Helps
eliminate expensive receiver damage and broken hammers. Fits
into the magazine well with the upper receiver open or removed,
withstands thousands of hammer strikes.
