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?"

We sent our friend Paul Glasco at Legally Armed America one of the first RMCS-4 Multi-Caliber Rifle Kits, and he put together a terrific video showing how all the components of this 4 caliber AR system work and interchange. Check it out on YouTube at: https://youtu.be/XLGDEuEIchM If you ever have questions about your rifle, you [...]
I've had a few customers call me since we introduced the Carbon Fiber rifles saying they were trying to install a free float handguard and the barrel nut would not fit on the upper receiver.
