Replacement components for the AR-15 that are made to strict military specifications. These high quality components will provide excellent fit and reliable function in your AR series rifle and are perfect for upgrading existing components or replacing worn or broken parts.
Notes: If you have to replace your AR gas key, it's a must to use new gas key screws. Mounting the key to the carrier requires two (2) carrier key screws
These screws should be torqued and staked. The screws must be staked. Use of a thread locking compound is not enough to hold these screws in place, and if they are not staked into place they may loosen during firing and damage your firearm.
