Crisp 3lb single
Reviewed on May 5, 2026Verified with Build

wall is defined at the advertised 3 lbs, break is straight and repeatable. reset is short and tactile, you can feel it with a closed grip. for a comp gun this is the right trigger

Timney 3lb breaks clean
Reviewed on April 20, 2026Verified with Build

Timney AR-15 competition trigger at 3 pounds breaks like glass. Self-contained cassette drops in any milspec receiver with a .154 pin set. No tinkering required. Worth the cost over a basic mil-spec setup.

Timney comp 3lb
Reviewed on April 13, 2026Verified with Build

3 lb single stage, drop in module style. pull weight is dead on my Lyman digital, no break in needed to get there. .154 pin size fits mil spec lowers. for competition rifles this is a benchmark

Timney 3lb reset positive
Reviewed on February 20, 2026Verified with Build

Timney 3lb single stage trigger has a positive audible reset that you can feel without looking down. Self contained cassette drops in any milspec receiver. Break is clean with no creep. Drops weight from typical mil-spec by a meaningful amount.
