|Purchased the extended mag release prior to attending an Appleseed event, and the swap was -very- simple and straightforward. -However-, on the first day of repeated use I experienced issues with the bolt release; the arm that engages the mag plunger is considerably narrower (~.0960") than the factory piece, and shorter in length by ~1/8". This caused the release plunger to 'lock' in a semi-compressed mode, and to release the bolt you had to go through a twp-step release; -very- difficult. I 'thought' modifying the bolt release plate would resolve the problem, but the bolt -still- didn't release. Swapping back to the stock release made the gun function perfectly.
Removed the UTG for good, and am shoping for a replacement. Price was good so I'm not hurt, but a hassle to deal with, especially during a timed event...|
