AR10 Dual Ejector Bolt

I'm a manufacturer and have found that KAK bolts are worth my time. We have started adding these to our normal builds and my customers are wanting to replace there bolts with these. We use the dual ejector bolts. They are so smooth and are going to be the new kid on the block.

If you want a bolt that is truly worth the money, this is it. Truly durable. And head and shoulders above all others. This is the one and done solution.

So I built a couple AR10 in 308. After just a couple rounds threw each build there was nothing but ejection/extraction issues and checking and rechecking things I decided to change the bolt heads out with KAK double ejector heads. Super easy and super quick swap out. Took the toys back to the range and well let them rip and rip they did. They now run without a flaw. KAK has the cure for 308 extraction/ejection issues. Would recommend to everyone with and AR10

I purchased a side charging LR-308 upper from Bear Creek Arsenal (BCA) chambered in .308 Win. One of the problems I had with it was that the brass casings would get stuck in the barrel and not extract after about 5-6 rounds were shot. The cause turned out to be brass shavings polluting the upper and riding into the chamber with each new round. Part of the problem was the barrel assembly—which I remedied with some heavy duty grinding/polishing. Another part of the problem was that the single ejector pin on the bolt was scrapping off flakes of brass from the bottom of the cartridge. I did some research and discovered this KAK double ejector bolt and decided to give it a try. It fit right into the BCA carrier and worked like a charm. Brass is no longer being flaked off the bottom of the cartridge—although I can see compression spots where the ejector pins come into contact with the casings. An added benefit is that the spent casings have a more consistent ejection pattern. (They mostly land in the same spot.) I’ve only put about 100 rounds or so through the rifle since installing this bolt, but so far I am more than satisfied.

Fit this into a Pa-10 carrier and have had zero problems. Put about 200 rounds through it so far but happy none the less. Original bolt failed to hold open on last round half the time and failed to eject two times per mag, through three types of mags, put this in and ran perfect, ran it dirty.. ran it almost dry; still no failures

VERY PLEASED WITH THIS BOLT. IT SOLVED THE FAILURE TO EJECT PROBLEM. NOW I HAVE A FEED PROBLEM AFTER SHOOTING 10 RDS

Fantastic. Replaced my Sharps relia-bolt with this KAK bolt assembly, and could not be happier. I was having ejection issues from day one. After trying several things, I finally spent the money on this bolt assembly and suddenly my M5 works great.

Had numerous failure to eject, with KAK double ejector bolt my LR-308 functions flawlessly! Best upgrade parts hands down,thanks KAK!

If you are getting a barrel from KAK then you should get one of these as well for your carrier, i put this in a palmetto state armory carrier and a 10.5" barrel from KAK and a 308 shockwave kit and they all work like a top! they are so smooth and work with steel ammo as well, i would always buy from here!
