You can buy the Timney Trigger AR-15 Drop-In Match Single Stage, Small Pin .154" here, as always we offer FREE SHIPPING on EVERY order!

Timney Triggers are one of the best investments you can make in your rifle. If your accuracy is suffering due to wide groups, a drop in trigger can help shrink group sizes by almost half. This is done by eliminating the slack and inconsistent break a standard trigger gives you. Timney Triggers provide you with a smooth, consistent and predictable trigger break. The default weight is set to three pounds at the factory and this is more than enough for precision work.
