Wondering about these I am seriously considering these does anyone have any experience with them? With dual MOA Barrett, ExRings with Pin-Lock速 http://www.barrett.net/optics/exrings Specifications
Configurations
New product for 2010 SolutionBarrett ExRings with Pin-Lock technology has a dual setting MOA taper at 15 MOA or 40 MOA, utilizing the riflescopes precise internal elevation adjustment by aligning the scope for long-range shooting. The front ring assembly is designed with a precision fit pivot that allows the scope to elevate in the rear, but tolerances ensure no unwanted movement. The rear ring assembly houses the Barrett Pin-Lock technology that allows the user to select from two MOA settings. Once an MOA setting is selected and the rings four cross bolts are torqued to specification, Barrett ExRings become a rock-solid mount with the correct taper to maximize the potential of your rifle system.
Materials and MassWhen selecting a mounting solution for your optics, strength and weight are two important considerations. The greater the overall weight of your complete optics system, the greater inertia (the tendency of a body to resist acceleration) it will have. When a gun is fired, it recoils with instant acceleration. A heavy optics system mounted above the bore axis will resist the sudden rearward movement. A light-weight, strong mount is the best way to combat unwanted sight movement during recoil. Barrett ExRings are constructed of high-strength 7075 T-6 aluminum. This material is ideal for the application due to its impressive strength; even more impressive strength-to-weight ratio when compared to heavier steels.
Holding AreaBarrett ExRings are wider than typical rings at 1.2 inches. This creates a greater surface area of contact between the ring and scope maintube. The benefit is a secure g |

It is a simple pin system it looks fixed once you change the pin and lock it down.

I have a set but have not used them on a rifle yet. When assembled the adjustment pin and pivot are blocked in by one of the side bolts that clamp (lock) the assembly together. The pins (pivot and adjustment) have a very tight fit and have to be driven out with a punch and a small hammer. The adjustment design is set up such that it is either 15 or 40 minutes with no in-between settings. I did consider changing the recommended spacing (9 slots apart) between the front and rear ring assembly to change the 15/40 minutes range but disregarded the idea because it would bind the scope tube. It might be possible to get in-between settings by leaving the rear (adjustment) pin out and relying only on the side bolts to hold zero, but would recommend against it for the obvious reasons that it could then slip. Over all they appear well made. dsr |

Thank you for that information.
I will only be using the 40MOA setting as that is more than I ever thought would be available in the rings alone and will help me to accomplish my overall goal. Edited by 338LAPUASLAP - April/17/2011 at 09:10 |

Wow, yours came in a nifty box with a Barrett name plate -- mine were only in cheap plastic.
I do like the disply name tag that they sent with it - nice touch.
