Yes, I was thinking I could use the bolt carrier for the Grendel build, and have a spare bolt for my Rem R-15. But, that kinda defeats the purpose of the NiB treatment???
Newbie question, would the spare bolt (NiB) have to be head spaced to the R-15? Or a new bolt headspaced for any AR, or are the machining tolerances tight enough that it doesn't matter which bolt is used?
I know bolts should be properly headspaced on Grendels, but didn't know if that was due to different bolt configurations, specs, type 1, type 2, etc, before the Grendel went SAAMI.
