MK25 and TiRant 45 Questions

[ejewels]

Hey all-

I am waiting on my AAC TiRant 45 can to be approved and in the meantime I am gathering everything I will need to run what I want. Besides the HK45, I also want to use my MK25 P226 as a host with it. I have two questions on what to buy:

1) Is there a special MK25 threaded barrel or do I just buy sig's p226 threaded barrel?
2) Which piston do I need to buy to use the MK25 as host?

Any help much appreciated! Thanks

1) No, you'd have to buy one seperate.
2) Don't know.

The question probably belongs in the NFA section but no harm done posting it here.


1) The factory threaded barrel should work since the light rail and parts coatings are the only difference between the Mk25 and 226.

2) Ti-Rant 45 piston, Thread pitch: M13.5x1 LH if you're using the factory threaded barrel.

Thumbs up to AAC for making 9mm pistons for the 45 Ti-Rant
