16x1 lh to .578x28 rh

  1. HK NFA TALK
    Would it be possible to re-thread the barrel of an HK45 from 16x1 Lh barrel to .578 RH? I have an osprey 45 and an M&P 45 host with .578x28 threads. I am very interested in buying an HK45 host but the only factory threaded barrels are16x1 LH. I really didn't want to mess with swapping out...
