Review: Rail Riser - Came packaged well. All the slots lined up just fine. Its aluminum not sure what grade but seems to be made well. The screws set up nice and tight and held up to several full mags of 300blk. Brought the sight up just were it needed to be. Matches up just fine!
Review: Excellent! - Nice product! Great price, I needed to measure to make sure which end was which for the 20 moa riser. Overall great value and foes exactly what it's so supposed to and looks great.

## Questions & Answers

**Q: I have an old Winchester tube fed .22, the scope rail is about 3/8” wide. Will this dove rail fit that so I can put a real scope on it ?**
A: No, this fits on the regular picatinny rail.  It is just a riser.

**Q: Will this fit a mosin nagant 9130**
A: Haven't a clue. I dont think there are picinenny rails on M-N's

**Q: it says 0 or 20 moa. Is it adjustable from 0 to 20 moa?**
A: I didn’t see where it said 0 to 20 MOA. I did see 0 vs 20 MOA. I had issues with my rails not being in spec and not able to accept my attachment. I tossed in the recycling bin as I waited to long to return.

**Q: which way is the front?**
A: You can mount either side toward the front. Its just a preference on what side you want the screws to be accessed from. That may be based off what hand you shoot with or setup of the firearm.

### ⭐⭐⭐⭐⭐ Excellent!
*by T***Y on May 14, 2026*

Nice product! Great price, I needed to measure to make sure which end was which for the 20 moa riser. Overall great value and foes exactly what it's so supposed to and looks great.

### ⭐⭐⭐⭐⭐ Perfect fit and finish, scope clears iron sights on ptr91 now
*by J***G on March 19, 2026*

Once again, Monstrum did not disappoint! I picked up the 1" riser so my Monstrum g3 3-18x50 scope would clear the iron sights on my ptr91. I was hopeful that i'd have a clear view of the front and rear sights as well...and i do! The construction is rock solid as usual - clean edges, very nice finish, secure fit. The hardware mounted easily.
