Good mount

Own 3 or 4 of these at this point. They work great and hold 0. 10/10 would recommend.

Flat-Top AR, Not for bolt-action rifles.

Seems solid for an AR scope mount. But buyer beware. When it says for flat-top ARs, it means for ARs and ARs only. This mount will not effectively work for some/many bolt-action rifles, it does not allow enough clearance for the bolt travel. Wished PSA would have spelled that out better before I purchased it.

This works great. The only reason I'm giving it 4 stars is I have the pro extend cantilever too and like it more.

Works

The magical bit between a vortex diamondback and 450 bushmaster AR. Holds up to the rattle of the AR action, recoil of the 450 BM thumper, and bouncing around on a wheeler rifle rack. Needs to come with a sticker though.

Fantastic, holds up perfectly

The gunsmith installed it easily, and there's been zero issues after miles of travel and hundreds of rounds

Amazing quality

I’ve owned this mount for about a month now and I can’t believe how much bang for the buck you get. I’m a regular shooter and when I shoot I spend around 6 to 8 hours at the range with my buddy’s and I’m surprised how well this mount can handle my .308S recoil and I haven’t had a single problem with the screws coming loose or rattling. even when I switch it over to my 6.5 Ruger I’d expect it to come loose eventually but it doesn’t I’m amazed on how well it holds even my leupold scope!

Great Quality

I purchased this for my Viper 3x9 and couldn't be happier. Fits great and looks good on my 308 AR.

ROCK SOLID- Easy to swap around

I swap this mount between two firearms. I have a Diamondback HP 2-7 mounted on it and couldn't say a negative thing about the setup!
