Customers praised this cantilever scope mount for "incredible build quality for the price" and excellent machining. The mount features marked torque specs, lightweight aluminum construction, and solid three-screw rail attachment. Most found it "perfect" for AR-15 setups with proper eye relief. A few noted manufacturing flaws like missing threads or scratches, and one suggested it's better suited for lower-recoil firearms.

Scope Mount at an attractive price

Scope Mount at an attractive price. Although this is not 7075 Aluminium, it is very high quality at a very low price. I would use this for anything but very hard hitting calibers and I plan on mounting it on my 6.5x55 SE Mauser 98 rifle when it comes back from maintenance.

It’s well constructed

And held my LPVO well. It’s well made with good fit and finish. Additionally, it’s extremely lightweight. One nitpick is the fact that the overspray from the letters are noticeable. They definitely used stencils and HOPED the paint wouldn’t get anywhere else.Other than that, it’s a good mount.

These are good scope rings.

They installed easy to the rail no problems there, All the dimensions seem correct as I didn’t have a single issue. comes with all the hardware to install but honestly a regular Allen wrench isn’t gonna do it you’re gonna need a special one that tell you how many ft lbs you’re putting on the scope during installation, well that is if you don’t want to risk over tightening and damaging your scope. If you know what you’re doing it’s got everything you need. The value for money is great here. Fit and finishes awesome and they look a lot more expensive than they are. And they look great. I put these on an AR 15 and a strike eagle scope, And I shot about identical, as the rings that came with the scope. These are bad ass.

Well made, lightweight, and strong

This mount is well made and quite lightweight. The mount design is allows for quick attachment and detachment. The mount comes with extra screws and the machined parts are clean and accurate. This mount provides a more secure option for your scope than standard individual scope rings for about the same price as quality pair. Be sure to measure your scope so that you know it will fit properly with the set distance of the mounting points as one of my cheaper scopes, which I intended to use this mount with, has too short of a distance to use it...what a bummer but it's my fault. Through the pictures you can get a basic idea of the quality. The mount uses torx fasteners making them easy to safely tighten. If this mount fits your scope and guns mounting parameters you cannot go wrong with the purchase at such a low price entry point.

Updated Review: Solid, Robust 30mm scope mount. Bunged-up mounting screw damaged the mount.

DISCOVERYOPT Rigid Precision Scope Mount,0 MOA Scope Mount, 30mm Cantilever Mount, 1.5inch Scope Mount, Picatinny Scope Mount Lightweight Rifle Scope Mount.This mount is a great combination of light-weight engineering and solid strength.I am using it to mount an LPVO scope on a .223 rifle, that I need positioned more forward for eye relief. I like the alignment lugs in the rings, and the heavy duty bolts.I am not a fan of all the torque values and tightening sequences printed in white on the black matte finish. Or the ring size and hight specs printed on the mount. Put that in the instructions. (well, there are not any..) That info is not needed after the mount is installed, and to me, it looks cheesy and amateur-ish. But, a minor complaint.Back to the heavy duty bolts: There are two extra bolts included in the box. And, all the bolts in the mounting base and in the rings are the same bolts using the same Torx wrench. This is good, because I needed a new bolt..When first loosening the bolts to install my LPVO scope, one of the three mounting base bolts was frozen, and very difficult to unscrew or loosen. When I finally got it about halfway out, I could see that the bolt threads were damaged. So, someone in the factory assembly had selected a damaged bolt and then proceeded to crank that thing forcefully into the mount. It damaged the aluminum threads in the base, but since the thread damage was in the middle of the bolt, half of the treads in the base hole were still undamaged. I used one of the extra replacement bolts to carefully "re-cut" the hole threads. It now threads in and out normally and holds securely. But, a disappointing discovery to make. I am glad it was fixable.This is otherwise a very well made mount.

Best optic mount for the price and it's not even close.

It's not a LaRue or spuhr but then again it's not 4 or 5 hundred either. For the price the quality is phenomenal. When it comes to firearms parts, increase in quality and increase in price are not parallel. You start paying a lot more for little increments of increased quality. There hold zero and didn't require any lapping. For 99% of the population there are beyond what anyone will subject them to. Now if I was being deployed to a warzone where my life was on the line, then I might have my reservations and not chance it with these. Who knows they might be nearly as good. Anyway enough rambling. These are excellent.

Nice quality for the Price!

I like the look and the weight of the mount! The frame seems solid and there are 3 Picatinny anti-movement locks. I like that the tension and torque specs are marked clearly on the mount and are easy for anyone to see. Helps mounting!However, there were some scratches and marks on the mount I received so I'm not so sure about Quality control here.

Slimline and super slick looking

This thing is awesome and very good quality. The rings have alignment studs which is good for those with shaky hands. The quality is awesome for the price and I look forward to trying more from this company. Top notch for little money. Get these and you will be pleasantly surprised.

Indexing studs & massive relieving make for a high-end, strong-yet-light high-p 34mm mount for cheap

There is pretty much no such thing as a HIGH profile 34mm mount with THREE solid recoil lugs under SIX ounces. Yet, here we are. And it has indexing studs in the tube mounts. Yes, that is correct. The fasteners are all 1st rate, the finish is flawless. I have a set of their 30mm straight rings and it is the same gig: massive over-delivery. That is my review: I am very impressed by what they do.Doing this review led me to shop their scopes. If this is how they are doing things, count me in. A++ all day.

Not top of the line, but great for the price.

I purchased this for a 300 blackout, using a vortex scope. It will have better rigidity than two piece scope mounts. The somewhat skeletonized structure will aid in the lightweight goal of this build. The printed torquing pattern numbers are handy for assembly, but I think I will color them in to make them less obvious. It's not a top of the line $250 scope mount, but for the price point and for the range of under 300 yds, this mount will more than suffice.
