Compatible with BCM duck-billed pistol grips, the BCM component also fills the “pinch” gap located at the back of the standard trigger guard when a baseline A2 grip is used. Finally, the edges of the trigger guard have been shaped to remove sharp edges found in the original design.
These nip and tuck adjustments deliver a significant ergonomic improvement, and positively effect the ability of the end user in consistent operation of the weapon system.
