5.0 Rating Bout Time - 2/10/2009
Reviewer: Andy
Bout time someone went back to the original "Stoner" style of retainer. Fit the pin pocket of the carrier perfectly relieving that concern of mine. Instructions are clear and concise. If you break it during installation, well, you just didn't do it correctly.

4.0 Rating Buy a couple - 12/5/2009
Reviewer: CBR Guy
I ordered 3 and before I put one in my Rock River I put a micrometer to them. These had variances of .018 inches. The first one I tried, the largest one, subsequently broke. The second one fit perfectly. A worthwhile upgrade, just buy more than one. If you don't break it you got a spare.
