OK- I've got an e-mail message into HotBarrel-
It looks like the Krink Gas piston is going to be way to short- reason is, you'd also have to machine the barrel for the retainer bracket belonging to the lower HG.
What I'm doing is removing the FSB, gas block, cutting the Bbl, and turning it down so that the gas block would be approx 2" further to the rear from where it currently is, the FSB will then go approx 1/4" in front of the gas block. With a US-made Krink style FH attached, the OAL is about 12".
(I keep saying "about" and "approx" because I don't have the Bbl Assy in front of me
.)
It sounds like to make this work, I need someone to custom cut a 3 1/2" or 3 1/4" piston?

For the purposes of conversation, what do you do about lower HG's if you're using a Romy G kit, or cutting down any other type to be re-born as a Krink??
