FORWARD CONTROLS BOLT CATCH/REALEASE ABC/R V3

Description

ABC/R has come a long way since 2015 (v1).  ABC/R v2 (2018) saw new surface texture (AA, or All Angles), reliability and compatibility tweaks for thicker upper receivers. V3 (2020) which replaces v2 incorporates feedback and input from users, as well as improvements we developed to make what is already probably the best AR/M16 bolt catch better.
