loctez Posted January 31, 2022 Posted January 31, 2022 (edited) Full disclosure, I know close to naff all about gbb pistols. I had a WE glock and that just "worked". Picked up a KWA CZ75 second hand, first few shots through the crono absolutely fine. Second mag in however the slide jammed and gas retention went through the floor, 5 or 6 shots per full mag. Excuse terrible photos but found all this inside the rif. I am guessing this is a failed part, any ideas what this would be? I am happy to strip it down further but will start with questions here. Cheers! Edited January 31, 2022 by loctez
EDcase Posted January 31, 2022 Posted January 31, 2022 Yep, somethings gone pop. Looks like plastic so have a closer look at the nozzle.
BigStew Posted January 31, 2022 Posted January 31, 2022 Can you give us a picture of inside the slide? Being plastic I would also assume something to do with nozzle. Also is the rubber in the top of the mag intact?
Guest Posted January 31, 2022 Posted January 31, 2022 KWA almost always fail at the nozzle seal first. All KWA nozzles seals are a kind of translucent rubber, so guessing it’s part of that
loctez Posted January 31, 2022 Author Posted January 31, 2022 Closer look this evening, looks to be component number 30 missing? Have I got that right, anyone know where to get a new one? Also unsure how to strip this down any further, assistance needed cheers!
