Just a little side note, I fired approx 200 rds through my rifle w/ a triple tap and then immediately switched to a similarly configured rifle w/o one and man was there ever a difference. Recoil was snappier w/o it and sights definitely jumped around a bit more before coming back on target. While firing with the TT isn't quite as light as a .22 LR it definitely does reduce felt recoil and the time to bring sights back on target. Though the trade off is in the report as it is quite a lot louder.
All said though, I wish Valkyrie Tactical had some in stock so I could order another one up for my build w/o one and I think I'm spoiled now, wont build another AR without one.
