FLATLINE OPS, INC. - ACCU/LEVEL ARTICULATING SCOPE LEVEL

A little pricey, but well worth it. It is amazing how much uncorrected cant will effect those long range shots

Excellent quality necessary for long range shooting I Have 3 on different rifles easy to see no cons at all

I have used scope levels since the 1990s starting with the simple Sinclair design and copies. What drew me to this product was the swing out arm to make seeing the level easier from behind the rifle. This gives you two options to check for cant and works folded out or stowed away because both positions are independently adjusted. Best part is you can fine tune the level at both positions without un-mounting it. This level is also designed in a split ring style that makes mounting easy without removing the scope from the rifle as long as you have room on the tube to slide the two parts together. I level my scope to rings in a badger jig and then the level the bubble at both positions. Simply the best functionality and easiest to level of any scope level I've used.

I have the 30mm on a Vortex AMG and a NF NX8 2.5-20. I liked the anti-cant level so much that I just bought this one to go on a NF NX8 4-32. I also have a 34mm version on a NF Beast. The levels are easy to see in either position and the ability to fine tune the level without having to reposition the mounting ring precisely is great. I have cheaper levels on my lower power variable scopes and the bubble damping and ease of mounting is noticeably less. The only con is the price but at least Brownells lets you pick them up with a discount and free shipping from time to time- even if you have to back order it.

I have one of the 34mm on my NF Beast and a 30mm on each of my two Vortex Razor HD AMGs. The mounting features that allow adjustment in both the stowed and swung out positions really simplify installation over other anti-cant devices that I have tired. The Flatline Ops are ruggedly built and have held up well in the field and at the range. I read the previous review about installation problems on the NF ATACR and checked mine but it turns out I used the NF anti-cant scope cap on it so I can't speak to whether there might be an issue for this particular application. I haven't had any issues with the ones I have mounted elsewhere.
