Broken Catch The catch is an internal piece that catches the plunger when you $!^& the gun and releases it when you pull the trigger; the resulting rush of air is what propels the dart. As a relatively small part, made of thin plastic, the catch is particularly prone to wearing out after heavy use. Once broken, it must be replaced for the gun to function normally again. Loose Catch Spring The catch spring is a small, but vital part of the catching mechanism. It gives some of the tension necessary for the catch to latch on to the plunger. Without it, the catch will not spring back into place after firing the gun. If the spring is simply out of place, putting it back into position will correct the problem. if the spring is stretched from heavy use, it may be necessary to replace the spring. Many online sources report that a pen spring may successfully replace the catch spring. See the Catch Spring Replacement Guide for more details.

Plunger Misalignment The plunger propels the bullets by air pressure. Often times after disassembly, the plunger can become misaligned with the holes in the barrel. Simply re-positioning the plunger so that its air flows directly into the barrel will solve the problem. Bad Seal in Plunger The plunger is made up of two tubes, one inside of the other. The outer tube is pulled back when the gun is cocked and forces air out the inner tube when the trigger is pulled. There is an rubber o-ring seal between the two tubes which forces the air to flow in the correct direction. If this seal fails, the air will not reach the bullet with enough pressure to fire. If this happens, the o-ring must be replaced. Home centers should have the appropriate size in the plumbing section, or a rubber band may be used as a substitute. See the O-Ring Replacement Guide for more details.

If the chamber is stuck its likely one of the following problems. Friction Between Chamber & Frame Using WD40 to lubricate the axle which the cylinder is resting on. Sometimes the cylinder will rub up against other parts of the gun if it isn't aligned properly, and spraying WD40 in these areas can make the gun work more smoothly and minimize any damage caused by friction. Cylinder Not Rotating Correctly Making sure that the cylinder doesn't have dirt, or anything that doesn't belong on the gun can be a quick fix. It's easy to get a small rock or dirt stuck in many different places of the gun. If a bullet doesn't leave the gun, but you hear it shoot the bullet, the bullet may be wedged somewhere in the gun causing an obstruction.
