MonstrumPrecision V2 Picatinny Scope Rings | 30 mm diameter | Flat Dark Earth

I have not taken these to the range yet, will update my review once I confirm the actual performance of these mounting rings. However, they seem to be good quality for the price point.To the 1-star reviews showing that these are not 1” diameter rings… of course they’re not. The description and product title clearly states that these are 30mm diameter rings. The measurement selection is for ring HEIGHT not diameter, as in “how high the rings sit about the rail.” The 1” is a medium height; .085” is low height. It is not the company’s fault that some customers did not understand this difference and these poor reviews do an injustice to the product.

Great rings for such a low price. I used these to mount my Hawke ED to my FX Impact.

I couldn’t find these anywhere at a better price. Appreciate being able to find parts and equipment on Amazon.

These rings look and feel 90% as good as rings 3x more expensive. FDE color always varies between products, do the match to my “mud” AUG isn’t perfect, and I didn’t expect it, but it looks very nice. Super solid, holds zero, on a Monstrum scope. Very satisfied

Thgey look good, but are not precission at all. Had to lap the hell out of them just to get them close. Had to be very careful torquing the top rings as there isn't much clearance. Had to remove and re-torque them 3 times to get an even gap on each side. Measured gap after torquing them to 15 inlbs, was .009" to .008", so you can understand why I had to remove and retorque them, as there is almost no clearance at all and it was real easy to bottom the ring on one side. Might have been a little more of a gap, but having to lap the hell out of them probably closed those gaps down some. Didn't take pics of the lap tools in place or the lapped rings interior (should have). Good thing I bought the Monstrum lapping tool with them, because I really needed it! The only reason i stuck with these was because they were the lowest height rings I could find at .85".

Rings sliped on rail, slots on rinds are too shallow

These are very good quality for the money however, when you put the top piece on it does not create a round hole the top alignment is off by maybe a 64th of an inch. Lapping these rings will correct that. Preferably get a kit that you can lap both rings at one time to ensure alignment and concentricity.

Paint scraped right off, clamp on rings wasn't wide enough to properly grab the rail!! Bad machining, Junk!!
