I’ll check out those dealers, any recommended specific for the receivers to be aware of?
The upper is a parts kit but doesn’t include a barrel.
I’ve been out of the gun game for a while; I’ll have to read up on the regs for what I can make.
So far: I have to use an HBAR, and not an A1 profile.
Forgot about that.
I recently put an M16A1 parts kit together but I have all the tools to assemble the lower and upper.
Assembling the lower is the easier part, putting on a barrel into the upper is harder and requires tools and knowledge (or fair amount of reading).
If you are looking for someone to do the assembly and do it right, you need a 20" hbar and either the FSB (tall version sight for the carrier handle rear sight) installed or the right diameter gas block for what came with your kit and the gunsmith to drill and pin it.
Since I have the tools to install a barrel, I got a barrel with FSB installed from JSE surplus and put it onto the upper then used most of the lower parts after cleaning them up. The parts they send need to be cleaned up before use.
If you don't have the tools or time, you will want to bring in the kit to have someone give you a quote. It may be as much labor as parts to do the work.
