Scope Bubble Level Indicator (Anti-Cant) for Precision Shooting, Competition and Hunting Fits 34mm Scope Level

This is the third scope level I have purchased from Lone Star Precision, it is well worth the money, is simple and well designed.The earlier versions had issues with the level vial coming loose, which I easily fixed with a dab of clear silicone adhesive on the inside edge of the vial.These are great for insuring that you are not canting (leaning) your rifle when shooting, for maximum accuracy. One very nice feature is the upside down "V" notch at the center of the vial makes it easier to see when you're level.The ONLY issue I had is the listing needs to state clearly that the 1"/30mm is the same product, (which leads to ordering confusion) nothing is said about it fitting both sizes of scopes. It is essentially a 30mm level, that comes with adapter inserts to allow it to fit a 1" tube as well.All in all it's a terrific product that I would definitely recommend.

Just installed three of these, 1", 30mm, and 34mm. The 1" is two piece with a screw on each side, the 30 & 34mm were the one screw puzzle piece type. I mount my scopes as low as possible, so I had to remove them to install, then relevel & zero. However, they all rezeroed very quickly. I have spent 5 to 6 times as much for other bubbles and none of them were better than these Lone Stars. They are well made, fit perfectly, and I love how the bubble is sized correctly to fit between the lines, much more precise. A fantastic level; I am going to order two more for other rifles.

The quality of this Anti-Cant device is very good. It was easy to install and stays put.The problem I had is visibility. If I placed it in front of the elevation knob (I'm a lefty), I can't see the bubble while in place to look through the scope. This means I would have to raise my head to see it and that is not optimal. If I place it behind the elevation knob, now it's difficult to see the markings on the knob and the bubble is too close for me to focus on it properly.If the bubble were just a little higher it would be perfect and get 5 stars.

I especially liked the scalloped window in the center of the level because it gave a very accurate way to ensure the bubble is clearly in the center of the leveling glass. I also liked that the application was ambidextrous since I was preparing a rifle for a left handed shooter who couldn't even see it around the scope "furniture" once installed. What I did not like was that the required inch/pound numbers were not included either in the packaging, nor was I able to find it anywhere on the web site. I use 25 inch/pounds to normally install my scope rings, but they are generally much more robust and heavy than is the level body. Some Amazon customers opined that they had torqued their installation screw to 18 inch/pounds, but were quickly scolded by another commentator who said 13 was safer and were less likely to damage the scope body. I used 16, but am still not sure if that meets the company's parameters. Since it is an engineered device, the company should delineate their inch/pound recommendations in the accompanying brochure. In addition, as was noted by another commentator, the small glass is loose in the holding structure body. Easily fixed, but an unnecessary issue.

The level was thin enough to install without having to remove my scope which was nice. It is solid enough and the single screw to tighten was great. I can easily see it with my Burris XTR II 4-20x50 without having to move my head from behind my scope. I could do without the logo on it, but whatever. It would be nice if it had a plastic liner or something to not mar the scope tube but I've not noticed any scratching yet. At $20 it is reasonably priced and it just works. I've not noticed any slippage after a day at the range. Would buy it again.

This level is great It's slim and not chunky like the vortex level that's so common. Its also way cheaper but the quality is top notch. The machining on the aluminum is precise and the anodizing looks great. I like that the bubble is retained by a c clip so it's replaceable should it break. I also like that it doesn't stick super far out from my scope. I wanted something fairly streamlined so it wouldn't catch on stuff and this is just right. It sticks out just enough to be seen around my turrets but doesn't stick past my parallax knob. Oh and the single screw installation is great.

I installed this on a 30MM tube, Nikon FX1000. Installation easy, bubble easily observed. However, if your farsighted you may need your readers to acquire bubble. Great value for what was delivered. Procured two additional levels for another 30 MM scope and one 1" scope. Works great!Ordering a 3rd level for AR10 in 6.5 CM project. Scope is an FX1000 4-16X50.Ordered a 4th level for a vortex viper pst gen II 5-25X50 FFL.

Top notch work. Pretty light, lighter than my older Vortex level. I like the center peak marker too. The only thing I don't like is that I'll need to remove my scope to get it on. It is just too big to fit between the scope and my rail. I have low Leupold rings on a pic rail mounted on my Tikka T3 Lite. I may take off a corner till the bottom piece will fit through. I'll make sure to have the next one one hand before I mount and zero my next scope. Made in Texas!Update: After I replied to an email from LSP, I got a reply in less then a minute. I was asking if indeed this was made in Texas. This was the reply; " I am not sure where aircraft grade aluminum raw materials are made but key components are made and assembled in Houston Texas lsp"
