Each unit is hand-calibrated: no creep, minimal overtravel and a break so repeatable it becomes part of your subconscious — exactly what deliberate match shooting demands. The 4 lb (1.8 kg) weight is the time-proven balance point: light enough for precision, deliberate enough for stages shot under adrenaline.\u003c\/p\u003e\u003cp\u003eThis is the trigger that introduced generations of AR-15 shooters to what a proper break feels like, in a self-contained drop-in module that installs in minutes and holds its calibration for the life of the rifle.\u003c\/p\u003e\u003ch3\u003eWhy shooters choose the Competition 668S\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand-calibrated 4 lb (1.8 kg) break\u003c\/strong\u003e — glass-crisp, zero creep\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong match record\u003c\/strong\u003e — decades on competition lines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-contained drop-in module\u003c\/strong\u003e — minutes to fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall-pin (.154 in) fit\u003c\/strong\u003e — standard Mil-Spec lowers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat the Competition 668S fits\u003c\/h3\u003e\u003cp\u003eDrops into small-pin AR-15\/M4 pattern lower receivers with .154 in trigger pins, using the existing pin holes — including UK straight-pull AR-15 builds, where the deliberate 4 lb (1.8 kg) break suits aimed, unhurried shooting.
