Monstrum1-4x20 Rifle Scope with Rangefinder Reticle and Medium Profile Scope Rings

Q: is the one power setting any good? could I use it with bolth eyes open?

Extremely clear glass, on 1x I could use both eyes open easily even on 4x I could. This company actually makes decent stuff for its price. Scope held its zero with over 500 rounds through it.

Q: Are the mounts good quality, and are they picitiny mounts?

Yes and yes. They are not the Burris PEPR knock off mount some Monstrum scopes come with, but they are a forward mount decent AR15 mount.

Q: How close of a match is the fde color to magpul fde?

I have one in the FDE color on my FDE Diamondback AR with Magpul FDE furniture. The scope color matches the rifle and furniture color perfectly. As far as performance goes, after getting it zeroed and putting another 200+ rounds through it that same day, it was still right on target. The 1-4 (actually more like 1.5-4) magnification is perfect for my needs and the lever to change the magnification is a big plus if you have to zoom on the fly. I opted to mount it using the Green Blob Outdoors Tactical M10 QD-L FDE Scope Mount instead of the canted black mounts that came with the scope. This put the scope at the perfect height for excellent cheek weld and eye relief for me on my Magpul stock. Next time out at the range, I took the scope off to zero the iron sights, put the scope back on and it was still on perfect zero. For a scope that sells for under $100 I would say that you can't go wrong with this Monstrum scope.

Q: What would I need to mount this to a mini-14 (ss w/ the black furniture)?

A rail or drilled and tapped for scope mounts.
