Only used a few times before deciding to part out my build, ergonomics and build quality are great for the price, really enjoyed it while I had it! magazine wall/trigger inletting has been dremelled out slightly (see photos) to allow space for the trigger hanger on an Impact 737R, this mod was okayed after a discussion with a product development manager from Aero Precision. $650, buyer pays shipping, will include the MK Machining adaptive precision grip (diamond texture) for an additional $35, open to offers.
