The BAT TR Action is identical to the VR action with some improvements for tactical shooting; A new extractor and ejector port for faster ejection, a new body design for increased stiffness, a new bolt design that increases reliability in dirty conditions, and a trigger hanger for tunable pin fall. This action is compatible with AI double stack magazines.
Made with 17-4 stainless steel, which is the preferred alloy at BAT Machine. The TR also uses a trigger hanger for easy trigger installation and action timing.
Bolt to receiver clearance is 0.0025″, to allow for smooth operation in all environments. TR’s are fully salt bath nitrided to harden the receiver, and can be ran with no oil or grease.
