Bolt and bolt carrier

Recommended Posts

Since DPMS is no longer and I want to shoot my Gen2 I will need some back up parts.  I'm thinking (trouble!)  that the part that would fail would be the bolt or the extractor, which leads me to my question, can I buy just the bolt or would it be better to get bolt and carrier together? What about head space? And lastly who makes a compatible setup?

What makes it better ?

What doesn't?

They set the bar pretty high when they were asked to fix common failure points on a weapon platform for our military.

JP EnhancedBolt™

  • Fully compatible with Mil-spec .223 and standard .308 subcomponents
  • Superior SAE 9310 material for superior resiliency and extended lifespan
  • Additional material around cam pin hole to eliminate inherent weak point of bolt design
  • Improved lug geometry for reduced wear and easier locking/unlocking
  • JP Enhanced Ejector design mitigates case head extrusions and reduces brass smear
  • JP Enhanced Extractor optimizes extraction function and eliminates multiple common ejection failures
  • JP Enhanced Gas Rings reduce internal friction and wear of the bolt carrier while maintaining gas seal longer
  • DLC coating offers super-high durability, lubricity and ease of cleaning

This may be a bit off topic but I bought a can of the new (well new to me) WD-40  Specialist water resistant Silicone spray lubricant. It dries quickly to a slick coat. I used it on door hinges drawer pull rails,  metal window glides and it appears to work.  I been wondering if it might be good on Bolt and Bolt carriers, buffers and buffer spring and maybe the charging handle. Has anyone tried it?  It is supposed to work at temperatures up to 500 degrees F.

Toolcraft is a solid product, but for just the bolt, they can't touch JP's offerings.

Cool - but overpriced for what you're getting.  Many companies do what they do - but JP caters to the RaceGun Crowd, so they charge premiums, based on what people are willing to pay.  RaceGun Parts - $$$. Ever seen the difference between a RaceGun bolt, and a regular bolt? Ever seen what the RaceGun Crowd will pay for a part that says "it's better"?...   :popcorn:

Lots of companies make their bolts from the same materials, same HPT and MPI tests...  the bolt is not a RaceGun part - but JP make it so, and charges a premium for it.  Enjoy it. :thumbup:

Coming from the one that knows everything you'd think.you would care to talk about the problems they were tasked to fix for the Government.

I don't by their products for the cool factor.

Well then, what .gov contracts do they have, and what were they "tasked to fix" for the .gov?  This is the first that I've heard of this, and I'd like to know...   :thumbup:

Ok so back on topic, I am unsure what to get (brands aside) I am assuming that I need a short frame type bolt carrier and bolt yes? (DPMS GenII)  I would also need to check headspace on the new set up yes? How do i rectify if it is different as I have heard people having spare bolts and carriers and wondered how they do that?
