Long story short, I have a few extra .311, 4140, 1/9.5 twist blanks left over from a project.
I was thinking about running some 7.5in. or perhaps 9.5in. pistol length, 7.62x39 AR barrels with the material. Threaded 5/8x24.
I'd estimate that when all is said and done they'd be roughly $200ea. and in typical Tech fashion, no corners cut
and of the highest quality and specifications.
Let me know if you want in.
