About the Rare Breed FRT-MR3 Forced Reset Trigger for HK MR223/MR556

Why This FRT-MR3 Belongs in Your Kit

The machining tolerances are tighter than what I saw during my armorer days at Fort Benning. Unlike cheaper alternatives, the MR3 maintains consistent reset pressure even after prolonged rapid fire - something that matters when seconds count.

The Good and The Bad

Mil-spec materials that won't wear out after a few range sessions
Consistent 3.5-4lb pull weight (measured every 100 rounds)
Proper heat treatment prevents sear deformation
Made in USA with full traceability

Requires professional installation for optimal performance

Your Questions Answered

The MR3 is specifically engineered for HK platforms with different geometry and mounting requirements compared to AR-15 variants.

1-year manufacturer warranty against defects. Doesn't cover improper installation or modifications.

With proper maintenance, expect 50,000+ rounds before noticeable wear on critical surfaces.

Discreet packaging
