Parts to complete bolt

**snackgunner** · 09-19-19, 06:46

I recently got a good deal on some ar15 stripped bolts that came with extractors.

Are the parts below all that's needed to complete putting the bolt together?

extractor pin
extractor spring
extractor spring insert
ejector
ejector roll pin
ejector spring
Gas rings

Anyone know a place that sells all these parts in a kit by chance?
Otherwise I was going to pick these up individually from brownells

BCM has a "bolt upgrade/rebuild kit"-
I carry a couple in my range bag.

Sons of Liberty has a rebuild kit. High quality with Sprinco extra power spring

They have some individual items as well

Their BCG OEM is Microbest which is one of the best IMO. Every component is quality

This is priced well. Just wish they had these kits without extractor

Do you know where the bolts came from? Are they proof marked? I ask because a SOL assembled bolt is like 40 bucks more than the kit.

They are spikes nickel boron bolts. Got them from a dealer who sells spike blem parts. Although I don't believe these are blems. They have no markings but look new
