This product turns a liability that is common to many AR and tactical stocks into an asset, by clamping directly onto a Picatinny rail, and providing ideal contact with a bench rest style front bag.
Anything that keeps a rifle from sliding smoothly in sandbags, either front or rear, will absolutely increase the size of your groups.
This product solves that problem for all stocks with Picatinny rails on the bottoms of their forends.
Its contact with the bag is identical to the best long range bench rest stocks.
To mount it, all you have to do is slide it on the rail to the position that you prefer, ant tighten three Allen head screws with Allen Key that is stored securely in the adapter. You will never have to look for a wrench or forget to bring it with you. It stays with the adapter.
