Monstrum Precision V2 Scope Rings | 30 mm Diameter

As always Monstrum delivers a great product at an affordable price!They are scope rings and work well and as intended, nothing bad to say about them. No stripped threads or screws, everything tightened down properly and secure. A+!Amazon shipping was fast as usual.

Came with all the parts that were needed and even came with a couple extra screws. Good grip holding the scope. Came with wrench, fit was perfect. Finish was good and looks to be durable. Haven't shot with it yet but I sure it will do the job.

A $20 set of rings, give them a chance. This was my second set purchased, the first was for my old 270 that I put a new scope on. Was I surprised at the quality and sturdiness of these units, very nicely made so when I replacer the Scope on my Savage 12FV with a better one with a 30mm tube I went right back to the Monstrum rings. I used to use Weaver but their over $50 a set now so I decided to give the Monstrum's a chance, at worst I would loose $20. They fit perfectly, the finish was excellent and when I dropped the new scope in them the bore sight was almost spot on, just had to raise the reticle a little. All in All a great set of rings, my 12FV just posted a .370" 5 round group 3 weeks ago and with almost 300 rounds downrange they are still tight. I'm a very happy customer.

These are quality mounts and very sturdy. The hardware is good as well unlike some cheaper mounts. The only reason I gave them 4 stars is because of the finish being worn off due to the mounts packaged together with no separation between them. I did not add a photo because another reviewer had already shown the finish worn off. I do recommend these and will probably but more.

First set of this brand that I have purchased. If my example is any indication, these rings appear to be very good quality, have "Torx" style fasteners, and are a very good bargain compared to the more expensive "name" brand rings. Very happy with the 30mm, .850 height set that I purchased.Addendum 3/27/23: (Applicable to the "WEAVER" style rings only!) Regarding these rings, be advised that the integral "key" in the bottom of the ring, where it clamps to the Weaver style rail, is not sufficient in width to properly engage the rail so that it provides a recoil stop. This integral "key" needs to be wider in order to properly engage the slots on the rail. If using the rings that are designed for PICATINNY style rails, these should be OK. Again, if using the rings designed for the WEAVER style rail, be advised not to use them if a positive "recoil stop" to prevent movement of the rings/optics is desired.

As long as you aren't shooting something super long range or with a crazy amount of recoil on it, these rings will hold up just slapping them on and going to town. If you need more out of them, I would lap them and really take your time mounting. Mine were initially a little off when I mounted the scope without lapping the rings but all I did was swap the location of each ring and my scope was dead on. Still recommend them for the price for sure.

Good mountsWould buy again

They appear to be well built and the Machining seems to be okay. Not sure I would trust higher caliber or a precision rifle.
