First Set of Questions:
I would not feel comfortable populating or headspacing without someone experienced advising and watching me through the entire process. The riveting I think I could handle on my own and I have a friend with manual riveting jaws very similar to the toth tool rivet conversion.
1.) My question is how long would the populating and headspacing project take, assuming I had found someone with the equipment and experience to help me? Is this something that can be done in a few hours one afternoon?
2.) As far the receiver goes, would you recommend a flat; 80% or 100% receiver?
Assuming I have someone helping me, I would assume drilling out a few rivet holes on an 80% receiver wouldn't add much time to the build, but a non-heat treated flat seems like too much work for a first build.
3.) What do you think about these pre-populated ROMY barrels?
I don't actually need anything but the barrel, however the barrel is already headspaced to the original trunnion. So I would think I would simply press it out an inch or two, rivet the trunnion, and press it back to where it was with no populating needed - just a quick check with a set of no-go gauges. Granted it would be a used barrel, but I don't really care for my first build.
The seller had 25 of these kits which don't appear to have sold, would it be worth it if I could get one for a good price?
Basically, would this save such a significant amount of build time that people would be more willing to help me or should I just stick with a new AOA nitrate barrel?
