My plan is to first get the trust in place, so I have the name ironed out, and then have it engraved on the 74U LLC receiver when it's made. I can get the receiver on order and start the paperwork at the same time, I'm thinking.Send it to Mario, this is a pristine, expensive kit, that deserves only to be build by the best.
Get a stamp first, I hate seeing Krinks with barrel extensions.
AKs, are not hard to build, I am sure you can do it, but nice kits are very expensive + building tools are about $500 for the whole set, which won't be worth it, unless you have 10+ kits to build.
I don't like permanently attached barrel extensions either, but I like it even less when the threads on the FSB are buggered from being pinned so I don't think I'll bother with that stage before the full SBR.
As far as tools I have a machinist buddy that has made some, so it would be more about the risk of a poorly executed build than tool cost.
