Okay those are all good options. I had talked to a gentleman who made barrels which I had bought before and he said that much material removed from the receiver wasn’t very safe. I thought about taking the 450 bushmaster barrel I had originally intended for my Kar98a, and sticking it on the reworked receiver since it comes with a locking ring. I purchased and old 8mm barrel that looks like it might have been a guild gun? Maybe? And sticking that on my Kar98a to give it some life. Unfortunately the sights don’t line up and that Is a project that will also need to be tackled. Thanks for the help!
