Absolutely great.


Best option I've found for folding an AR. Better than the LAW Folder, hands down. Beefy, rugged, and a very intuitive folding mechanism.

Fan-Freaking-Tastic lower!!!

This lower is very nice in fit and finish. The integrated folding is great and doesn't have the slop in so many of the add-on folders. Having the extension on the buffer rather than added to the bcg is much better and allows you to open the upper from the lower without removing anything to do so. One of my favorite lowers so far!
