Testing out the Deflector Brake, which is a disposable, peel, stick and press accessory for AR-15s. It absorbs some of the energy of ejected casings and reduces the speed and distance the brass travels. It minimizes damage to the brass which increases the reliability and efficiency of reloading, and it deflects spent brass forward and away from the shooter making AR-15s safer for left-handed shooters.

Several months ago I bought two pistol uppers - a 10.5" .458 SOCOM and an 8.5" .300 BLK. This is a function check and the first shots fired from my new AR-15 pistols.

Best .450 Bushmaster mags I have used and also work in the .50 Beowulf and .458 socom.
