At that price, no way, no how. It's been a long time since Physics and Engineering classes - but I cant see how this device can reduce felt recoil more than just adding dead weight to your stock. Just be sure the dead weight you add is "securely fixed/attached" to your stock. If it is free to move slightly with the recoil impulse - it cant do its job. Also, did you notice 2 of the weight pieces in the kit are made of aluminum. Aluminum ! No thanks.
