Screw fixed stock for Kalibrgun crciket

[qlj890219]

I owned a wood CRICKET .25.unfortunately,my friend lost two screws which fixed the wood stock.I want to know the specific model of the two screw.
In addition, I don't know if it's metric or american system.

Also,how I can connect the refill adapter?The thread is metric?What model of connection I can use?

The threads on the fill probe are 1/8" BSPP which is the same as on most fill probes which don't use a foster fitting. 1/8" BSPP to 1/8" quick disconnect (foster) are easy to find.

I found this while searching for the thread size of the stock screws so if you found that out please can you let me know. They don't fit anything on my screw chart measuring thing so I assume they are metric.

I have the cricket carbine not bullpup. The two screws are just an M5x? and an M4x? (? meaning I don't know the lengths I'm at work) but it should be easy enough to figure out how long of a screw you need. They are regular old metric threads though.

Thanks. 

Please can you tell me how you identified them? I.e. Did you measure or was it from a parts list somewhere?
