Shooting the Mossberg 590 Shockwave 20 Gauge

Sarge over at C4 Defense asked me to do a video on my 590 Shockwave 20 Gauge, so while at the range last night my wife filmed this short video of me firing it and the results to the target. I was using Remington Express XLR #4 Shot at 10 yards. I also learned that the SBA3 is probably not the best brace to use on these Shockwave "not a shotguns". I'll be swapping it out with the SBM4 that is currently on my AR15 pistol.
