KSC USP Compact problem with sliding

Ayashifx55 · July 30th, 2009, 01:56

I just traded this off and i started to shoot with it. First, i went to SurplusIG get a adapter for propane and a 5$ big propane bottle from canadian tire. And started firing. Everything went well, shot about 40 shots. As i shot, i realise the hop-up was badly adjusted so i un-assembled , removed the barrel and putted back everything. Then, after assembling everything, i started firing again and i saw all the gas popping out of the gun, i could only fire like 2-3 shots and the gas was empty (i loaded the mag full of gas) then i got scared and unassembled it again to see if there was something wrong.

Nothing wrong, started assembling it again , tried to shoot. No more crazy leaks. Ouff .... but things started going wrong, for example, after each shot, the metal slide didn't slide properly, it would over-slide towards me , so in order to continue to shoot, i have to push the slide back to where it belongs to and shoot again.... Then i disassembled again and assembled again and here's the result :

What's wrong with it? I never had a handgun before ;(

SOLVED BUT DON'T KNOW HOW. I JUST RE-ASSEMBLED EVERYTHING AGAIN ..... SORRY FOR WASTING YOUR TIME. BANANA

Thats good & all.....Look forward to taking your blowback unit out and having to put the rubber O-ring back in the metal groves when it blows out of place. (this will cause all the gas to release at once)

Double wammy!

You do realize what silicone oil is used for, right?

Uh....did you replace your recoil spring and guide properly? It looks like you didn't....or something else major...

I'm not sure what silicone oil is for but i'm pretty sure its a must for every propane charge. Each 2-3 times propane recharge, i put 2 drops of silicone oil on the valve of the bottle and then i put back the adapter and then refill the mag. Though, i have read that Green Gas is only propane but pre-oiled with silicone oil but at a much higher price , though they smell better. Therefore, to compensate the propane cost, silicone oil is needed. That's what i have learned so far.

Guide is in japanese

Is it normal that sometimes i see some gas spreading around my gun? Not every shot is like this but it does it randomly.
