SOLD!! FS: Timney Drop-in Trigger 4# for AR-15 SOLD!! I am selling a like-new Timney AR-15 modular trigger (fire control group). It is factory pre-set with a crisp pull of 4 pounds. Installation is quick and no adjustments are necessary—this is a true drop-in trigger. This is a small-pin (.152-.157) unit and fits most all AR-15 lowers except Colt. The unit comes with all the original parts and installation instructions. Used for no more than 20 rounds; I sold the rifle it was bought for and am selling the trigger separately. I’ll sell it for $149, and ship it free. I’ll accept Paypal if you want to use a credit card.
