Not For Bear Creek Upper

Written on Oct 14, 2023

Bought one of these mag adaptors to try in my side charging Bear Creek Upper receiver. It keeps jamming rounds up at a 45 degree angle striking the top of the breech face. I contacted MEAN Arms and was advised this insert will not work with the Bear Creek bolt that feeds from the center of the mag. The MEAN only works with a carrier that feeds from the side of the mag, not center.
