Re: pre threaded barrel install
Like Gaslight said its only saving time on the threads, IF that.
Threads might have to be chased still, and if the Remington has been trued and opened up, the aftermarket barrel wont even screw on correctly because the threads will be undersized.
<span style="font-weight: bold">We'd charge $200 to install a short chambered/pre-threaded barrel, and put our name and guarantee on it.</span>
It's almost just as much work as starting with a contoured blank.
Plus, the smith will be expected to produce a half MOA rifle with a barrel that <span style="text-decoration: underline">someone else</span> did work on, and ran a reamer in.
The reamer your smith uses, and the reamer the barrel company used will not be the same. If it was short chambered with a standard reamer, then your smith uses a minimum spec "tactical match" reamer.... I dunno. I just dont like the idea.
Im not a fan of short chambered/pre-threaded barrels.
