Upping this to 5 stars. I received the wrong color, sent it back and got the wrong color again. I originally rated this 2 stars. I contacted Mostrum support for help. It turns out they're out of tan. They offered to refund (without return). Although a very generous offer from Mostrum, I declined. I'll keep it. I'll use it. This is a great scope mount. It's height is perfect for me. My scope sits tall and I can position it above the charging handle and have plenty of space to charge. Lots of mounting screws. The bottom of the scope sits 1 3/16 above the rail. I'll update this after my next 500 rnds on how well it holds up. If you don't mind black, get it. Great quality at a great price. Edit: ~500 rds 55gr 223 and no issues. It's holding up well. No locktight. I still test the screws each 200rds or so.

I used my Wheeler alignment/lapping kit on this to see how good it was. Alignment was good between both rings. The pictures from lapping speak for themselves--looks like the mount needed it. The machining left some grooves in one of the top ring halves. In fairness, I didn't keep track of the top pieces the first time I took it apart--it may have done better if I'd marked them first thing. The threading seems to be good quality but the screws turned roughly in the holes. From what I can tell, they are not tapping the holes oversize to account for the added thickness of the anodizing. I ended up chasing all the threads with a tap to clean them up and the screws turned a lot more easily. I don't think this is something you _need_ to do. I already had the lapping kit and tap so no additional cost for me, but I spent a couple hours getting the mount up to the next level. I don't have a lot of spare time these days so in retrospect I think I would jump to the $60 range where less fussing would be required (but let's be honest I might have fussed with a fancier mount, too). And I have heard of folks needing to lap nicer mounts. Overall good value for the money. IMO most scope mounts are ridiculously overpriced for what they are. Nice to see these at a price regular folks can afford. $100 scope plus $30 dollar mount will work just fine for most folks (not everyone is trying to shoot a hair off a fly at 200 yards).

It fits my Bushnell scope like a glove! Just make sure you know what size you need first.

I have to be brutally honest, I over rationalized this purchase. I have always been a Leupold mount fan, no matter what scope brand I bought. But I had a hard time rationalizing spending $100 for a mount when the Monstrum was starring me in the eye at less than $35. I researched the Leupold and the Vortex and decided well that the Vortex was probably made by the same factory in China and the Vortex reviews talked about issues like top mount color that the Monstrum folks said so I rationalized the Vortex was made by Monstrum. I bought the Monstrum and I am amazed! This mount is perfect in every way. I am not sure why all the complaints on the screws, if you use a torque wrench there are no issues. For those of you who don't own one, well then you should not be installing your own scope. Stop complaining! Install when amazingly smooth. no issues. I like the 4 positive locks on the Picatinny rail, unlike Vortex who only has one and Leupold only 2. The screws are all Torx and no issues there. Take my word, save yourself some money and get a great product, I am a fan for life!
