I'm getting the bolt from kak. Did you need to upgrade the firing pin? No change to the bcg?
Thanks.

TL I'm sorry it took me 3 months to see your question... I dropped the ball on enabling notifications. I used the SPR contour that X-Caliber offers. I did the full KAK bolt carrier group, and that came with the high pressure firing pin. AFAIK, the bolt would be a drop in if you wanted to use another carrier. As for whether the high pressure fp is a must... I have absolutely no idea. I don't want to give you bad info. Let me know if/when you decide to pull the trigger on building one. I've loaded up some ammo, but still can't seem to find time to shoot it. I started with h4350, but I have some h4831 and h1000 in reserve in case the h4350 doesn't do the trick. Loading 175 eld-x bullets for now
