AR-15 Pins falling out:
When installing your Timney Calvin Elite AR-15 trigger be sure to
tighten down the set screws once the pins and safety are in place. No torque
wrench is necessary, hand tightening should be sufficient.

AR rifle double fires:
AR doubling can be caused by several factors including incorrect installation
procedure, disconnect distance being incorrect, or user error. If the trigger is
installed correctly and the distance is correct the issue can be the response to
recoil of the shooter. This is frequently an issue with prone shooting since it
is more difficult to get a good tight shoulder weld on the stock due to the
Timney’s AR line of triggers feature a very short reset. That short reset is
critically important for fast follow up shots. A shooter can essentially relax a
finger and the springs will guide the hammer to reset the trigger for the next
shot. While this feature is a premier function of the AR trigger it is also a
contributing factor in double fires if the shoulder is not snug to the stock
The recoil pushes the stock into the shoulder, the shooter stays in the trigger
squeeze through the shot, following through to the end of the range of motion.
If the shoulder is not square and or snug so the recoil is properly absorbed by
the body, the rifle will recoil forward from the shoulder and because the reset
is so short the rifle will fire a second time. This is commonly referred to as a
bump fire or bounce fire.
To prevent double firing be sure to keep the shoulder snug to the stock through
the shot. If the rifle recoil causes it to bump off of the shoulder relax your
finger so that you don’t inadvertently squeeze off a second shot.
Practice squeezing slowly and deliberately through the shot, squeeze the trigger
until the range of motion has stopped. Once it is complete slowly relax the
finger, listen and feel for the triggers reset. You will not need to pull the
finger off the trigger but rather relax into the reset of the trigger. Once you
have found the reset be sure to feel for it when shooting from other shooting
positions, especially prone or from a bench/shooting stand.
