Timney Skeletized AR-15 Triggers
Skeletized Replacement of AR-15 Fire Control Group
  Timney Triggers for AR15 are also called the Fire Control Group. This unit replaces creepy two-stage triggers with a single stage that is smooth and crisp. These triggers are available pre-set for 3 lbs or 4 lbs pull weight (4 lbs AR10). The installation uses your original hammer/trigger pins and the system eliminates pin rotation and walkout. They fit ARs with "small Pin" (.152-157") Hammer/Trigger mechanisms.
