KAK K-SPEC AR15 Bolt 5.56/300 Blackout, Dual Ejector
The K-SPEC dual ejector system uses mil-spec ejectors and springs that require no proprietary parts. Ejector holes are centered on the lugs to avoid any reduction in strength of the bolt. The dual ejector system increases the ejection reliability and adds consistency to the ejection pattern. KAK Industry has been manufacturing dual ejector bolts for the AR10/LR308 platform for over a decade and has used that experience to create a durable and reliable dual ejector system for the AR15 platform.
The K-SPEC Bolt is backwards compatible with all standard mil-spec BCG components. The K-SPEC bolt can be used in any AR15 style direct impingement system.
- Bolt- 9310 steel, outside diameters ground to .0002 tolerances, MPI test, nitride finish
- Extractor- 4140 steel, fully machined, Phosphate coated
- Extractor pin- S7 tool steel, ground, heat treated
- Ejector- S7 tool steel, ground, heat treated

having fired thousands and thousands of rounds from Colts (w. 20-10.3″ barrels) in semi and FA mode over the decades with minimal problems or parts failure, i see no need for KAK’s “solution seeking a problem”…. especially with 9310 bolts.
I was thinking the same thing along with, if there was a problem, wouldn’t colt have come out with a fix years ago? If it ain’t broke, don’t fix it.
Not to be confused with knights armament corporation out of Florida.

Ok, I am late to the party on this one but I think I have a question that is prevalent. I understand that somehow having two ejectors makes for better ejection but my questions is, if one breaks will the rifle keep operating? If one brakes and stops operation, can it be cleared and continue operation?
Inquiring minds want to know.
Tell me again how extra complexity to combat an uncommon point of failure (for most people or well maintained arms) and that it’s own failure won’t be noticed until the back up fails is a great idea? Explain to me how diverting dirty spent gasses more directly into the fire control mechanism is a good idea. I could be wrong. Let’s repost this article in a few years, as Ammoland sometimes does, and see if we get any customer testimonials who have 10k or 20k rounds through the bolt. I do commend them to holding 2/10000 tolerance.
Well, it’s only been two months but, whoop there it is!!!!
