Made the switch from shockwave blade - SB Tactical SB-MINI Pistol Stabilizing Brace for AR Pistol Buffer Tube Platform

This cost a little bit more than than the shockwave blade but was worth it. After firing hundreds of rounds in 1 day with the blade, you'll start to feel it on your collar bone / shoulder. After putting the SB mini, there was an immediate noticeable difference in comfort. This brace is alot more comfortable and has a smaller profile. Mine was stiff to put into the buffer tube. I just used a rubber mallet to tap the brace in slowly to make sure everything lined up.
