are JP enterprises bolts worth it?

[PredatorDown]

Somewhere between 2500 and 3000 rounds on my JP bolt/barrel, I broke the extractor. Sent them an email with a few pictures, and they sent a new one out to me. Bolt itself is still going strong, and now has nearly 4K rounds through it.

I've been beyond happy with all of their products that I own, including their AMCS chassis for my bolt gun. Machining looks to be top quality
