Set your head space pretty much like normal, and add a click or 2 extra to compensate for the chamber insert and test fire, check the fired cases and adjust from there if necessary.
The Complete conversion is $400.00 + shipping and includes 100 of the new Nylon links, New Booster nut, Barrel, Bolt, Top Cover Spring, Recoil Spring and cartridge stop/guide.
For all of you out there, I will have a new conversion for the 1919 coming in the fall. 7.62x54r and it will run from standard links and maybe web belts estimated price is $550.00 + shipping
