Monstrum Precision Picatinny Scope Rings | 30 mm Diameter

Ran a 30mm Hougen Cutter through these then set them up on level. True with 0.000 run out. The same result juxtaposed with more expensive rings. Granted I didn't mount this on a 30-06; none the less it's nice to see what you're working with. These are solid I deducted a star for the fastener. These appear to be pressed in not solidly bolted in. I'd like to cut one of these in half to see just how the bolts are secured. The dilemma of buying imported stuff. It's so generic that one can assume the name is just that. Slapped on and expected to perform. So do they? Do they hold and maintain zero? Yes, after four months yanking it. What do you think about my kitchen countertops?

Attempted to mount a Nikon 30mm MRAD on my .308 but here we are with a scope that still isn’t mounted on my rifle. This product is cheap. I should’ve ran once I saw the price and the reviews... all went well until I tightened things up. Then I stripped out one of the ring bolts with an Allen wrench - by hand!! I mean really? Then the bolt that tightens the assembly to the rail stripped out and just free spun on the bolt. After surgically removing the rings from my scope, they went straight into the trash. This is easily the cheapest firearm related product I’ve ever had the displeasure of using. Do not buy. Just spend the extra dough for a quality product. Monstrum = garbage.

Nice fit and finish.Threads are smooth.Very little back and foward slop and solid fit.The 1" height works perfectly with a bull barrel and a 50mm objective lens on top of a 20moa rail.

I will start by saying that I tend to buy expensive scopes and rings, and if I do buy low end rings I will usually lap them. I wasn't expecting much out of these. But what can I say, right out of the box they were already straight and got good contact with the scope. Torqued the nuts to 20 in-lb, which was slightly more than 1/4 turn past hand tight, and the ring bolts to a little less than 20 with purple loctite. Those are the values from the monstrum website. None of the fasters felt like they were in danger of stripping. I suspect some of other reviewers have drastically overtightened. On my best scopes, I use ARC rings that are about $180 a pair. Obviously I would not replace my ARCs with something like this or really with anything, but its just worth reflecting that you could in fact buy a usable pile of these rings for the same as one pair of high end American rings.

Fit the scope great. Easy to mount. I also like how it has 2 screws for more stable mounting. Most scope rings only have 1nlock screw to mount the rings to the rifle rails.

I don't know how they can make these rings this well and sell them for the price they do, but I would recommend them, and that comes from a guy who has had guns since the 1970's.The ONLY issue is....lol I got 2 different rings...lol One is taller than the other, and at this price its not worth the hassle of returning them...I got spare parts or.....I could mount a 30mm red dot or prism optic with one on one rifle and one with the other.The fact that I got a mismatched set of rings does not detract from their quality.

Very good quality for the price and true moa height

Really well made and every bit as good as rings costing many times more. I highly recommend.
