JP Enterprises 'Recoil Eliminator'. Just googled it and they still sell 'em. Its interesting that they claim 'match wins' as validation of performance. Wait...what?
The pic I posted above was intended to be a bit humorous..ie a massive brake on an ar15, but in fact it is really as effective as it should be...even on a 223. Makes it feel like a 22lr. Just VERY VERY LOUD.
They were made for heavy magnums (with a larger version if you can believe it), but you can imagine the blast from that. Had one on a 30-378 Wthby that was super effective, but your head would ring if you were under cover like at a shooting range.
They are heavy too, this one is about 8ozs. Changes your POI by FEET. Whole different world for load development as barrel vibrations are massively skewed by this heavy bottom weighted mass at the tip of the barrel.
