LanTac Timing Shims for 1/2x28 threads let you index a muzzle device so it is correctly oriented when fully tightened. 1/2x28 is the standard thread pitch for most .223/5.56 AR-15 barrels. A small, inexpensive part that makes installing a brake or compensator straightforward, with no guesswork about final orientation.
