Someone else told me I should sign up here because my services might be of interest...
I had 3 different requests for threading these barrels in the last week to ten days.
I finally got one in the shop last night and made the special barrel wrench.
I can now tear down and rebuild these uppers to thread or shorten, thread and permanent attach a muzzle device.
So I can take your rifle from this:
to this...
This is a single-point threading job done on a center so it's already setup for a suppressor with no fear of baffle strikes.
I can do standard 5/8" long threads for AR type muzzle devices or 0.400" long threads for popular 22 rimfire sound suppressors.
I can also shorten barrels for SBR use or shorten and permanent attach just about any muzzle device to stay over 16" length.
If you are in the greater los angeles, CA area, I off this service while you wait.
Otherwise, if you ship it in, it's a week or so (gunsmith time) turn-around.
$20 to remove and re-install the barrel.
$30 to thread the muzzle and re-crown.
$45 to shorten, thread and re-crown.
$20 to permanent attach a muzzle device you provide.
$15 return shipping for an upper.
