JaMesD Posted September 20, 2014 Posted September 20, 2014 This is my recently installed cylinder for my tm vsr 10 pro, I was just taking it apart to fit a hop up rubber and noticed these quite deep scratches. Does anyone have any ideas what is causing the erosion. http://puu.sh/bGFQ5/b8b88b7238.JPG Any reply would be apreciated
Moose87 Posted September 20, 2014 Posted September 20, 2014 looks like when its being fitting back in the rifle it was either put in wrong or there was something inside catching. it looks like its been forced in by someone pushing and twisting side to side. did you buy it like this or did you do this??
JaMesD Posted September 20, 2014 Author Posted September 20, 2014 I did it my self as it is a new cylinder
Moose87 Posted September 20, 2014 Posted September 20, 2014 you must have been pulling on it quite hard to get it out then to make that damage, have a look inside before you put it back in to see it doesnt catch on anything and make sure you are putting it in properly
Supporters Rock-climby-Dave Posted September 20, 2014 Supporters Posted September 20, 2014 that'll be the bolt that holds your trigger assembly on to the bolt housing causing that. As stated earlier, snaking the bolt side to side whilst removing it is causing the zig-zag look. just file the top of the screw down slightly and make sure that there aren't any burrs on the piston (file/sand any off gently) and reinsert everything. It should drop in with little to no resistance. Unrustle_Thine_Jimmies 1
Supporters NickM Posted September 21, 2014 Supporters Posted September 21, 2014 I had the same issue but at the top of the cylinder, turns out it was because the screws holding the scope mount were too long and therefore rubbed on the cylinder. I built up the underside of the scope mount with electrical tape. Looks like exactly what RCD said, before I put mine back in I made sure it was nice and smooth inside. team flex and beastmode 2
JaMesD Posted September 21, 2014 Author Posted September 21, 2014 I have checked all the screws and none of them stick out so i don't know what to do, but i did measure the old cylinder compared to my new one and the new one is slightly larger, maby that could have something to do with it?
JaMesD Posted September 21, 2014 Author Posted September 21, 2014 And also when i put the old cylinder back in i dont have the problem
team flex Posted September 21, 2014 Posted September 21, 2014 james, that just means you have to sand down the inside a bit surely, so it fits in?
JaMesD Posted September 21, 2014 Author Posted September 21, 2014 yeh i know but i was just wondering if anyone had a better solution
