I recently had need for a pin & weld for a muzzle device on a 14.5" Colt SOCOM barrel. I contacted John Thomas at Retro Arms...

John was prompt to respond to emails and did a fantastic job with a great turnaround time at a reasonable price. I would post pictures but I don't have a camera with the precision needed to see the detail...the work is that clean.

I realize that pin & weld isn't something that's done very often as most folks simply go with a 16" barrel or SBR setup, but in the event someone needs this service, John does outstanding work and is great to deal with. John also offers a number of other services.
