Called Model 1 Tues and ordered a 16in CAR kit in 7.62x39. Also asked for the enhanced firing pin for Russki ammo. She told me it now comes with it and prob be a week or two. Just got an e-mail with a tracking no. Should be here MONDAY! Have to put the upper on something to try it out as I haven't even started on my 80% lowers- just got them back a few weeks ago from Pirate as I sent them to him to engrave for me!
