Hi, I have a quick question that if anyone can answer would help me massively.

 

I bought a CYMA 701b sniper (VSR-10 Replica) and also bought the NOVRITSCH upgrade kit, so I have successfully installed the new sears cylinder etc.. but I can't seem to access the hop up chamber/inner barrel. The main receiver and outer barrel don't screw off because there seems to be some kind of screw holding them together (like in most VSR's) but this screw doesn't fit any Allen key or screwdriver I own !! it's very small and doesn't seem to come out. does this mean the outer barrel and main receiver are crimped together thus making it inaccessible? 

 

many thanks, mark.

It should come away, if you unscrew the first bolt holding the rail in place.

 

if it’s that small, it may be pinned. But I’ve not heard of this before. Might just be a real small Allen key
