Timney Trigger AR-15 Trigger Features The Timney Triggers AR-15 Trigger is built as a 100 percent true drop in unit meaning it installs into a compatible lower without requiring adjustments fitting or tuning to perform correctly. Its large pin design specifically matches the 0.168 to 0.174 inch trigger pin diameter used on pre 2005 Colt AR-15 rifles a detail that matters because using the wrong pin size trigger in an older Colt lower can result in poor fit or unreliable function. Constructed entirely from steel the trigger holds up to repeated dry fire and live fire cycles without the wear that can affect lighter weight aftermarket parts. The solid non adjustable design eliminates the pin rotation problems some competing triggers experience after extended use. Breaking consistently at 3 pounds the trigger offers a noticeably lighter and crisper pull than most mil spec factory triggers which commonly run in the 6 to 9 pound range with a mushy gritty break. This improvement in trigger feel translates directly into better shot placement and faster more confident follow up shots. Beyond older Colt rifles the trigger is also compatible with standard mil spec built lowers as well as select Mossberg MMR and Ruger SR-556 platform rifles. For a shooter looking to meaningfully improve trigger feel on an older Colt AR-15 or a compatible mil spec build the Timney Triggers AR-15 Trigger is a dependable upgrade available for sale at GrabAGun.
