Mk12ish DEAD AIR BRAKE
by Tyler Frogley
Admittedly bought it from forward controls because it hadn’t released here. Absolutely love this brake. It sits on a mk12 clone build. I emailed DA about 3 months before this came out and stoked that someone did this.
Quality Piece of Kit
by Bradley Matthews
Just received this Expo Arms / FCD muzzle device and installed it today. First would like to note that when torqued to spec on my barrel, no shims we’re needed as the device properly indexed off the bat! Second, the quality of materials and finish seem to be on par with Dead Air’s own devices. Third I’d like to state that the overall length of this device makes it cross-compatible with both Dead Air’s KeyMo and KeyMicro mounting systems! Will be putting a lot of rounds through this device in the future to see how it will hold up.

Got me to 16inches from 13.7 My build is mostly FCD parts figured if Roger paired with expo arms the product is GTG!
