customcutter Wrote:I assembled mine and no problems that I was aware of. However, I will say this is my first build and first time I've assembled a bolt. So with that said I wouldn't know if there was a problem unless it jumped up and bit me. Still waiting on mags and a scope and thread protector/muzzle device. I did look to see how much firing pin extended past the bolt face and noticed it was very little, so not worried about puncturing primers.
I had a few other manufacture of bolts earlier this year from Tactical Ammunition and R-Guns. Those 2 I don't have now but did notice the firing pin issue of it protruding further. I did measure the bolt face (.135) but didn't think to measure the Bolt OAL. One of the 2 of them had less firing pin protrusion so must have been shorter (modified 223/556 bolt). I never knew there was a difference in length till Maxum told me they compensate (made the bolt tail longer) for the deeper head space to keep the firing pin in the correct place.
As for the extractor, I have Extractors from Maxum, not the ones from Satern. I am sure Satern got those bolts with the groves on them from Maxum but got extractors from there other bolt source. So when people get theirs, I would like to know if they notice what Sputnik was talking about.
I don't think it will matter but as Spuntnik has noted, it does make contact to indicate wear.
