Well I recently acquired a couple of snipers in need of some repairing (I'll be dealing with the L96 in a different thread

). I've done well so far with my own AEGs but I'm needing some help with these spring'ers.
For instance, this sniper is I believe just a run of the mill VSR-10 Clone (with a nice custom paint job). However, the piston sear is worn down and in need of replacing. After scouring Canadian sites I was able to find this first and second sear for the TM VSR-10 (if anyone knows where to get just a piston sear in Canada, feel free to tell) from here:
http://www.airsoftparts.ca/store2/in...roducts_id=650. However, since the owner of this gun has no clue what or where the gun comes from (it was originally his cousin's) I have to somehow confirm for myself just what the heck it is and if it is TM compatible before I start ordering parts. There are no markings on it aside from the regular "warning misuse may result in death; read manual blah blah", and on the butt-plate it says "Made in PRC" (People's Republic of China I'm assuming)" so that at least confirms it is indeed Chinese-made.
I did manage to fire off a few shots with it with .28 bbs and it is definitely not your regular Walmart crap-gun, it could definitely handle .30s no problem.
Anyways, any advice in the matter is greatly appreciated.
