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.
