machining a twistlock into a cocker

[BTAutoMag]

who can do it?

[HolySokz]

Xmagterror
is offering it with his bodys. I don't know if he offers it on the side, I'm still new here. :)

What type of barrel?

I think this can be done, but would have to cut the twist lock up to the breach opening, making it shorter barrel.

Ken at KPCS has done it, sorta. had a Lapco bigshot that was gouged by a wire detent that was caught by the bolt, and Ken rethreaded it.

Xmagterror and Super Stancy Customs are the two that I know of that offer that service at this point in time.
