Bradrock, I am not sure what your timeline is like, but I have a new PKM stock at home that i can give you the tracing for. Its going to be a couple months before I can do it though. I may be able to send you a tracing for a solid yugo stock if you would be interested in that. Send me a PM.
Since I have no experience plugging barrels, ill probably spring for a new one from Prexis. Fluting sounds interesting. I have not seen fluting on barrels here in country, although they appear to be yugo's and may be different.
Im excited to see the kit now. It's like waiting for Christmas. Except Santa used my wallet.
I wish RTG would get top covers back in stock. Their price seemed pretty reasonable. I have a friend doing some searching for a top cover now. I'll post if he comes across any that seem reasonably priced.
Still working on the measurements. Just have to remember to put a measuring tape in the kit next time we roll out.
