John Thomas -- Outstanding AR gunsmith

[mpddoug162]

I had John modify a barrel in addition to modifying and grafting a bm59 fh-mb onto the carbine barrel for a prototype build. Excellent work and communications along with fast turn around time.

I mostly lurk here. John recently drilled and pinned two Daniel Defense barrels for me, work was completed day the barrels received and in the mail back to me. To say I am pleased would be an understatement. Plus he stayed in touch with me via email when I first reached out to him to ask a couple questions. He will now be my number 1 go to for work.

Does he pin and weld suppressor mounts?

What about timing? Does he require shims sent with the muzzle devices or have his own?

Call or email him. He's very responsive to inquiries.

I think this is just Euro being a troll again, mockingly asking newbie questions.

Some companies don’t pin suppressor mounts because they are harder than ordinary muzzle brakes, or at least they charge much more for it (See: Adco)

For a simple untimed shim, here's the job John did on my M4, with a spare shim for another project.

That looks like a compression washer (or whatever the tech term is), and not a shim. Its always possible I'm wrong, but if a can is ever going to be used a shim is desired. Some people also prefer the look of a shim, though the compression washer is certainly quicker to install.

^ There’s a shim behind the crush washer.

There's 0.2" of shim behind the standard crush washer--even in person you have to look REALLY close to see where the Colt barrel stops and John's shim begins. The spare shim is set aside for a possible 12.5" build on a 12" Centurion C4 Pocket, in case my "Ersatz GL/SSC" goes forward and takes that path.
