Yep, another broken-extractor thread

[BluntForceTrauma]

I sell the exact same bolt as Black Rifle Arms, so I can't say anything bad about 'em! (Although my price is $55, not $75 — and not $85 like BA. Good to be in The Horde! )

I've had two customers break extractors on my bolts — and these are the correct Grendel-specific extractors with the unusual "hump" near the head of the extractor, rather than the scallops that you see in a 5.56 extractor. This hump is necessary because of the larger Grendel rim diameter. Anyway, extractors sometimes break for various reasons. The claw will typically rip off at the extractor groove juncture. Nature of the beast — and it's good to have a spare whether you're 5.56 or Grendel.

I've tweaked my bolt design so that my next batch will be slightly improved over the current model that Black Rifle Arms and I sell, having a slightly thicker rim upon which the lugs sit. I'm also working on slightly improved extractor specs, but it's hard to get any manufacturer interested these days when they're selling everything they have flat out.
