Send us your AR15 upper, and we will machine the RevoltMfg “Gas line” cuts into your AR15 upper.

This RevoltMfg gas lines upper is a sweet addition to a suppressed AR15. This upper has 10 slots machined at 30 degree angles forward to direct gas away. Hot gasses naturally rise, so it seemed best to let it go where it wants! We used the charging handle to show that it acts as a block when installed, so nothing can sneak in the machined ports. We currently have all employees who shoot suppressed using these uppers, and they love them.
