Why This FRT-MR3 Belongs in Your Kit
After running this trigger through 500+ rounds in our Nevada desert tests, I can tell you it’s built different. 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.
