## Questions & Answers

**Q: Will this retain 0 with iron sights on a AR15?**
A: I would not recommend this, they bend and as far as maintaining zero I’m sure if you dropped your gun that would be it. I can’t even use them both on mine because the rail I have on mine is shaped slightly different than the rest of the upper and the grub screws that hold it in place push on the part that is shaped different so the angle was already off.

**Q: will this angled rail take the recoil of a 12 GA shotgun?**
A: No it won’t. I returned mine. It is flimsy trash held on by tiny little set screws. I spent a lot more money and bought Midwest Industries 22.5. degree offset rails for all three of my rifles, one of which is a .308. They are rock solid and I much prefer the difference between 22.5 and 45 degree mounts.

**Q: Made in USA?**
A: I don’t think so, I returned mine immediately as they wouldn’t stay on my rifle and I tightened it down as tight as possible without bending it.  Cheaply made and not recommended.
