[Jbone 11 11]

I just bought a TM Gen 3 G17 from Mach 1. I did not fire any round through it as the slide arrived a couple of days later from Airsoftdepot.

I installed the slide no problem, its fairly easy...some tricky bits but over all easy. When I test fired it, it would cycle, but bb's would just roll out of the barrel.
I took it appart and restored the G17 to TM stock set up in case the TM was defective. It fired perfect. I went through two mags to be sure.

So I reinstalled the Ace kit, but oiled everything that moved real well with silicon oil. I worked all the moving parts (Piston, slide etc) and then tried another mag. It shot 70% of it, with the other 30% miss feeding or rolling out the barrel...even got a slide jam from multiple bb's getting stuck in the chamber.

So apart it all came again. I noticed the inner barrel was real stiff inside the outter barrel due to an o ring at the end of the outer. I tried oil...it seemed to help but still stuck a bit. So I removed it. Tried another mag...still misfeeding and misfiring.

So then I puled the piston, hit the piston with a real fine grit incase there was issues with it cycling smoothly. I cleaned it up, iled everything nicely and tried another mag. Again, I got 70% fired ok. I tried another and only got about 20-30% of the rounds out.

So I am at a loss here. All reviews I've seen of this kit are nothing but great. No mention of needing a harder spring (an idea a friend had) to cycle it properly or anything remotely similar to these issues.

Wondering if any TM Glock Gurus out there can hit my with some knowledge.
