New gun double shoots.

[JStribSTSg3]

Hey I just purchased an sts g-3 from xpaintball.com
, i'v only shot it a couple of times and every time it starts to double shoot. Like when i pull the trigger it recocks twice like an automatic only it shoots one ball. If anybody can help me out i'd appreciate it thanx.

You may have a "defective" sear meaning that the sear is not catching and is worn.

Try oiling (just add about a drop or two on each o-ring) the Striker O-rings or changing them.

I tried the oiling thing and it stilll does it the o-rings look good but i guess it won't hurt to change them, thanx.

Two simple things you might want to check before you get elbows-deep into part-replacement.

1. Is the frame tight and flush on the gun? (ie no space between the frame and the grip) Any space between these parts translates into a shorter trigger pull. If you've got some plastic flashing from a badly cast grip in-between holding the grip away from the body, it might make the sear too short to grab the striker. Also check for bits of casting-flash inside the trigger mechanism area on the frame. Little, extra fins of plastic will interfere with the smooth operation of the sear.

2. Is your thumb touching the sear release lever when you fire the gun? It doesn't take much movement of that release button to interfere with the gun re-cocking. Check how you're holding the gun and see if you need to watch this.

Check the interfacing surfaces of the firing mechanism for wear or poor condition. The striker has to have a smooth, flat shelf on it for the sear to grab, the sear has to have a sharp, un-chipped corner. The trigger itself has to be smooth on the edge the sear rests against during a trigger pull. Check all the pins for excessive play/slop-- a pin that shifts under load might reproduce the movements associated with firing the gun.

My last suggestion is that your valve pin may not be letting enough air through to re-cock the marker, so the striker is double-tapping the valve to get enough air past the valve to re-cock.

A stronger spring might help (by increasing valve dwell) but it will also increase your minimum muzzle velocity. If you have an extremely low "lowest possible velocity", you may want to try a stronger spring.

A high-flow valve-pin will increase airflow to the striker, making re-cocking more certain at the expense of muzzle velocity.

Try all the other options (including taking the gun to a nearby airsmith) before you start adding "performance" parts to it--they cost too much to buy "on a hunch".
