## Questions & Answers

**Q: have winchester sxp long beard mossy oak obession 12 ga. Will this fit that gun? what screws come with for mounting**
A: It did not fit my Sxp Longbeard 24in. The screws came in M8 and we’re too big for tapped holes. Had to order different one.

**Q: will this fit my Winchester SXP Super X Pump Defender 20 gauge (has the 4 factory top holes/screws)**
A: hey JPW, I purchased this rail to use for a scout mount on my Ruger 10/22 The hole pattern match the forward hols in the top of the 10/22 receiver to cantilever out over the barrel to move the scope forward,  there is a bunch of spec and fitment info if you scroll down the product page to, Works for these compatible models, but not limited to: Take Care
