Part needed for a Cricket carabine

I bought a cricket carabine from a forum member and it's missing the forward stock attachment (barrel band) and the screw to hold it. This part is only found on the long gun (carabine) .. I've sent some inquires out to several sources but haven't heard anything back

The part numbers are POL-136 for the barrel band (they call it a sleeve) and SPJ-5 for the stock screw.

Anyone know of a sources. I sent Charlie Frear an email and I haven't heard back. He may get back to me and if he does I'll let you know.

Anyone know of anyone else. I also wrote to Kibrgun directly. Again nothing 
 
Are cricket carbine parts hard to get? I ordered a cricket carbine from krale and they emailed me the next day to tell me the stock got damaged. They ask if I wanted to wait for a new stock. We played email tag for a couple months. Then told me they recommend me buying something else. So they may have a hard time getting parts. But they were great keeping me informed, And didn't want me to be disappointed.
