I use this product to aid in accurate shot placement and long range shooting. It's proven to be 1st class in design and durability. The glass can be seen easily from a cheek weld, and requires no loss of focus on sight picture from scope. Also, the bubble cover can be screwed on the opposite side thumb screw for storage during use, a bonus to prevent loss. I've used other products that mount to the tube of scope, and you really can't be sure of zero canting during firing because of the required movement of your face position. Also, this item can be moved from rifle to rifle (Picatinny & Weaver mounts) making it very cost effective! This is simply an awesome product, and I highly recommend it!

Poor level. Level bubble ...

Poor level. Level bubble changes at different angle positions and if you tighten the thumb screw with different force, the bubble level moves also. My Stanley level that I bought at home depot is better than this $80 level as far as being truly level. Better to try your luck with their fixed level, although I heard there's problems with the fixed units as well. U.S. Optics is not as perfect as they seem and need to have better control of their quality if they want to stay on the top.

Just what I needed

By Richard in Ocala

from Ocala, Florida

Comments about U.S. Optics Anti-Cant Device Picatinny and Weaver Style Bases Swivel Matte:

Looked all over for something unobtrusive and that worked. USO came through again. Bought two of these swivel models for two rifles. They arrived three days earlier than promised. I have seen where people say they change level on the torque settings? My box clearly states 10in/lbs. I used a FAT wrench from Wheeler, and torqued to 10in/lbs. Nothing easier than that. They stay level with the scope and barrel and that's just what I was looking for. Range tomorrow.

GOOD QUALITY PART , DOES JUST WHAT IT WAS DESIGNED TO DO , BUT (USE LIGHT TORQUE) ITS NOT A HEAD BOLT TO A MACK TRUCK . SHOT TO SHOT CONSISTANCY IS THE KEY NOT LEVEL TO THE AXIS OF THE EARTH.

Comments about U.S. Optics Anti-Cant Device Picatinny and Weaver Style Bases Swivel Matte:

I've used this product and like it. While some have raised concerns regarding the torque changing the level point, if you mount the bubble with the scope you will get level-level-level.

By ROWDY

from BENBROOK, TX

Comments about U.S. Optics Anti-Cant Device Picatinny and Weaver Style Bases Swivel Matte:

Purchased this for my ar-15 flattop. Works perfectly. Mounts good and tight. A little overboard on the price but it is worth it. Highly recommend the folding version. If not, the level will stick out off the side of the weapon about 2 inches where it stands a chance of getting knocked off.

By Robert

from Keller, TX

Comments about U.S. Optics Anti-Cant Device Picatinny and Weaver Style Bases Swivel Matte:

I've had this device for a year and must say it works well. Can shoot 1/2 to 1 MOA at 1000 yards and this device definitely contributes to that. I didn't realize the natural cant that I had until I started using this. It's easy to glance at it with the the left eye while keeping the right eye on the scope. I must say that it is more than a bit over-priced as it's just a level with a swivel and that is why I only give it 4 stars.

By J

from Fairbanks, AK

Comments about U.S. Optics Anti-Cant Device Picatinny and Weaver Style Bases Swivel Matte:

Concept is good, and mounts easily. The design needs work. The amount of torque you use to mount it determines how the level will read. The same can be said when you rotate the bubble out. The torque screw that is done by hand determines how the level will read. Bottom line it is not consistent. There are much better products out there.

I completely agree with Mr. J. Woods. I have used mine, and never thought I naturally canted as much as I did. Excellent Product.

By Hugh

from Frisco, TX

Comments about U.S. Optics Anti-Cant Device Picatinny and Weaver Style Bases Swivel Matte:

This is a great product, but a little pricey. I used it to help align the scope cross hairs and of course it works well on the range. The screw on cover can be stored on the off side, but watch out. If it's tightened too much, it backs off the Picatinny clamp when you go to remove it.
