Anti-Cant level for Picatinny rail

1. Yes.
2. Vortex makes two piece units too, they're not as nice as the Lo Pro version.
I had a look and the one piece unit is not as bulky as the two piece one that I have and would be good for those running very low mounts. Reasonable price too if you shop around. 1648994490405.png
$49
 
I started out with the cheap picatinny rail levels and since they were cheap I started feeling guilty and purchased a few more expensive brands. I then started checking them against each other using some levels that I borrowed from a surveyor friend of mine. Some of the cheap ones were off, as were some of the higher end brands. I then had an epiphany (nice word, don't get a chance to use it much) and realized that consistency is the key. If your level bubble is consistently off but you leveled it every time you shoot then it will not matter. Level your scope, reticle, level, stock and if it is not comfortable to your form it will show on the target with bigger groups. One of my rifles is perfectly level but it has a chassis that is just an ergonomic nightmare to me. To get everything level I feel like I'm doing some really bad yoga or something. Weird, but true.
 
The level must be mounted to the scope and then mounted level to gravity. And then you never remove it. It's as simple as finding something level and pointing the scope at it I use a roofline in the distance, and then you set the bubble at perfect vertical tighten it check it and then never remove it from that scope ever.

I use the $9 levels I buy on eBay I must have 20 of them by now. I'm pretty sure all those little bubbles come from China. And I know for a fact that Vortex is made from the same parts.

But if you write tactical on it, that guadruples the value.
 
My favorite is the Flatline Ops Tango. It is accurate, reliable and tucks away when not needed. The adjustment screws can be tough to reach around scope turrets if you don't pay attention to where you attach it but that's my only beef with it.

The Flatline is the one I settled on and have been very pleased. Once set up and in agreement with my Spuhr mount it has not moved and so far the hinge mechanism has not failed and the ability to fold it out of the way saves digging a hole in the foam of my rifle case.
 
Compare a Rail mounted level to a scope mounted one.
Put the scope (with level of your choice) on the rifle.
Don't worry about level yet.

Install a level with adequate sensitivity on your unlevel rail.
Level the rifle using just the rail level.
Hold this.

Level scope reticle to plumb line, while keeping rail level.
At this point the rifle, scope, horizon are leveled to the Rail level.
Normal for a rail level to this point.

Now set scope level to rail level. Check horizon with either level.
Readjust if needed by setting horizon to rail first then scope level to rail level.
After a while remove the one you don't like :)

What I have found is a rail level will force me to hold the rifle at an unnatural cant. I can still shoot well this way only off a bench but it does feel awkward. Scope levels for me!
 
I saw a rail with the level built in at back end. Pretty slick. Precision Hardcore Gear Tru Level, $90 at Midway.

The level in in the rear mount base but I get the idea... It just confirms that the scope mounted level is also accurately leveled... I can see the rail mount level and just confirm that there is no cant before touching off a shot... The one in the Sphur mount I only use when setting up my front rest on the mound as during shooting you would have to pull back and lower you head to effectively see it..
Sphur does make their own version of side mounted level that I have not used but would also be an alternative to the rail mount as it attaches along the side of the rear or from mount and inline with the centre line of the scope...
