Gunsmithing aftermarket barrel for LMT MRP upper?

[Spdy]

I picked up a MRP upper up and will start shooting it once the weather warms up. I know LMT uses a proprietary extension on their barrels that is not available separately and have heard Marvin Pitts can machine aftermarket barrels to fit. Anyone know of a source for these extensions? Is there anyone else that can machine an aftermarket barrel to fit a MRP upper?

Marvin is your best source. I've sent him more barrels for work on gas guns then I can even count. I wouldn't look much further. He is the man for the job.

Thanks JW. Do you know if Marvin will work with all brands?

Yes. I've had him work on pretty much anything AR15/10.
