One piece scope mount

[Spdu4ia]

Trying to find a one piece scope mount without spending $400+ oh a sphur. What are some decent other one pieces available? Also what are the specifics of the advantages over regular rings?

I've got a spuhr, larue, and various brands of rings, I honestly like the american rifle company rings the most, they are solid, simple, and pretty much bombproof. They also offer a 1 piece unit.

I have larue and bobro... Both offer zero shift when removing the scope.

I like the bobro requires zero adjustment regardless of the rail width.

Larue provides a little wrench to adjust tension. Their tension mounting system has reports of wear on the upper receiver, although I've never experienced it. I guess if you're constantly removing and reinstalling your optic it would wear. (I have 3 larues)

Quick disconnect isn't required for my purpose

I like a JP mount a lot: http://www.jprifles.com/1.6.3.6.php

I have the JP. But I don't know of any advantages.

Good ones guarantee perfect alignment so you don't have to hone. However, I've never had to hone quality rings on a one piece base, so I'm not sure how important that is.

Some one piece mounts drastically limit fore-aft adjustment. I passed on a Spuhr for exactly that reason on my bolt gun. As much as I like the idea of one piece mounts and Spuhr in particular, I think rings are the answer for a bolt gun.
