The O-ring fell off my Brad Nailer, which was causing the trigger to drop off.
Randy - October 3, 2018
With the new O-ring, I was able to line the trigger for the Nailer and put the screw back in. Then the O-ring slipped right on. Very happy that it was quick repair.

I bought my Bostitch 18 gauge nailer at a pawn shop when I needed an inexpensive nail gun. However, the trigger would not reset unless I put my finger on the backside of it and reset it manually. I ordered a new trigger, safety bar, and retaining o ring and for $18 in parts (including shipping costs), I wound up with a nail gun that works like brand new!

Tore the nailer down, removed the worn parts, cleaned the parts, replaced the worn parts, lubricated all the o-rings and assembled the gun and all is well.

1.Remove 2 screws holding the trigger block and trigger.
2.Remove broken trigger pin.
3. Put the 2 screws back into the trigger block first. You cannot attach the trigger with the pin first without breaking the pin while tighten the one screw on the side with the O-Ring. ( That's how I broke the pin in the first place.)
4. Tighten each screws a little at a time until both are fully tighten.
5. Repair is completed and gun works great.
