  • Awesome product! For the price you can’t beat it!
Color: Black Size: 30 mm
Great product for the price comparison of name brands!

  • Great product - misleading color
Color: Flat Dark Earth Size: 30 mm
This is a well-made mount and the quick release works well. The only issue is that the pictures and description are FDE - but what arrived is a washed-out olive drab green. Probably would look good on an all-black rifle, but not on other colors. Hated to send it back.

  • Good quality for price.
Color: Black Size: 30 mm
Seems to hold ok. Would like to see a little harder aluminum alloy. Have not removed yet and replaced to check zero accuracy. I suspect it may require very minor adjustments to maintain perfect zero. I like the design. Clamps are a little too easy to adjust and I fear having to readjust tightness each time they are removed and replaced. Good value for price! ... show more

I was sent the wrong package to begin with, and parts were missing. Contacted seller and they were AWESOME!!!! They had another package sent out immediately and was delivered extremely fast. Product works as described and I will see if it holds up to the test. Overall great mount for the price

  • Good budget mount
Color: Black Size: 30 mm
This Monstrum one piece scope mount with rings is a good buy. Quick delivery, light weight, and sturdy. The quick disconnect feature is a great thing. Scope mounted easily and the hardware that was included seems good. No instructions, but most folks can find any information on youtube. This item is made in China, but the cost difference from the major name brands is significant. I'll see if this mount and rings hold up to repeated recoil from my rifle. I recommend this if you are on a budget. ... show more

  • Seems ok
Color: Black Size: 1 inch
First, You should understand there is a very specific way to install this type of 'Quick Release'. If you don't do it right, you'll damage the mount and it wont get tight. Ever. That's why you see the negative comments about this mount. Now, It went on nice and tight, scope mounted up nice, laser zero'd it and next week I'll live shoot it and see how it stands up the recoil. Update to follow. ... show more

  • Read this before purchasing, I am only here to help
Color: Black Size: 1 inch
I put this on my AR15 with a Vortex crossfire II 2X7. I did much research on this mount and the scope, which I am writing a review for now. (the scope is a bang for the buck best you can get for 120$ IMO) Okay, for the mount, you will need a torque wrench to place the scope inside the rings properly. I hand-tightened them, and the scope moved after about 100 rounds. After putting 18-19 inch pounds of torque on the scope rings, it is totally secure, and the scope has not moved after 100 plus rounds. Do not exceed the torque of, let's just say 20-inch pounds because you will strip them out or crush your glass in the scope. It is challenging to gauge how much torque that is without the inch-pound torque wrench. I recommend investing in one. The screws that mount the rings to the rails are super soft (the softest I have seen on anything I can remember hardware related). I could not get more than 30-inch pounds without the flathead screwdriver threatening to strip the screws (sources say to tighten it to 40-inch pounds). Use the correct-sized flathead screwdriver and be very careful you will strip these screws much easier than you think. This is the significant flaw in the mount. The only way to secure the mount to the rifle securely also subtracts the ability to use the levers to quick-release the scope and mount. If you put this mount on an airsoft or .22 you potentially could find the sweet spot to use the quick-release feature. If you intend to use this mount on anything more powerful than a .22 forget the use of the quick-release feature. However, this is still an OKAY low-cost mount without the cool quick-release feature. I read in the reviews that someone replaced the soft rail screws with some from a local hardware store, and they were able to get a much tighter torque from the mount to the rail of their rifle. I have not tried this yet but not a bad bit of information to hold on to. Overall, man, I love a good product at a low budget cost (hints the scope, which I am very happy with) this mount just does not quite qualify as what I would consider a good purchase. It caused me more headaches than it was worth. That being said, I am still using it until I have one more issue. I am a budget man through and through, so if you don't want to take the risk of a headache as I did, you'll have to spend more money. I will write or update this review if anything changes, but right now, with proper torque settings, the mount meets but does not exceed my shooting needs or expectations. Just remember this is a low-cost mount, and that usually leads to some things that will need to be worked out for you based on your needs. Do not expect a super high-quality mount for this price. ... show more
