Giving credit where it's due. Absolutely gorgeous weld job by Pullman Arms in Worcester. For a job like mine, one can really see the advantage of their connection to Micro Arc.
For my AR-6.5 Creedmoor build, I dropped off my 20" Ballistic Advantage barrel for 'neutering', aka permanently attaching the Lilja thread protector. I wanted to keep the barrel legal for shooting the the AR-Tactical class, so a muzzle brake was verboten and of course in the PRM a flash hider could get me a room with bars. my only parameter was that I wanted to keep a flush surface so that a low profile, one-piece gas block could be installed or removed at will. Result was really nice:
A small chamfer was made (their good suggestion) to keep the weld below the OD and maintain the clearance I required. Even with high end equipment, a weld that sharp takes skills and deserves kudos.

. Nice do they do aluminum also? I have aluminium? I assume .![[grin]](/xen/styles/default/xenforo/smilies.vb/041.gif "Grin [grin]")
Need to see what it looks like when the rifle is complete and at that point I might either bead blast the cover to match the barrel, or possibly coat it. In the end, it's a consumable so I may just leave it alone. Barrel life for 6.5 CM isn't as bad as 6 CM, but nowhere near as long as for .308. Lilja was the only place I could find a stock .875" diameter cover with the AR-308 5/8-24 threads. 
robably they can weld aluminum. They do both micro laser and micro TIG. IIRC, both can do aluminum. Micro Arc Welding, 508-852-6125. Seems like 22LR wouldn't be too violent on the op rod.
