Tapco t6 recoil pad....works like a charm - Tapco Collapsible Stock Recoil Pad T6 M4 16607

Quick and easy to use. Keeps rifle butt from sliding on floors when leaned up against a wall or in truck/bed. Also keeps stock from sliding around in your arm/shoulder area. Fits standard size AR M-4 style stocks just fine and fits SKS telescopic/collapsible Tapco stocks perfect too....well of course....it's for that very stock anyway. Does have a tad bit of weight but it's good rubber and plenty of it. I like it plenty good and works as advertised. Will not fit the smaller butt end on C.A.R. stocks though....to big/tall.
