AR10 BCG- DOUBLE EJECTOR (BOLT CARRIER GROUP) MPI

Great bcg looks great functions even better and for the price you couldn’t beat it

I work professionally as a Gunsmith there are alot of products I see come through our shop that have failure to eject or extracting issues especially on larger ar-10 platforms. The KAK industry 308 double ejector bolt carrier group is not one of those products. I assembled my upper and test fired 10 rounds into our clearing barrel we have in our shop, the rounds flew so far away I still have not found the spent brass. The quality of machining and craftsmanship is outstanding. If I ever build another ar-10 for myself of a customer this bolt carrier group will be in it guaranteed.

Built my first upper from multiple components, (bought a few complete uppers of various makes) I built a AR10 wildcat upper with this BCG. I think I will make KAK BCG my go to for all my builds if I should do any more

I bought this BCG for my AR10 build. With the duel ejection ports is what really Drew me to make this purchase giving that added port and having an adjustable gas system will give you that added ability to tune your rifle to run any ammo.

After emailing kak about the bcg I received not having a firing pin they sent me one right out. Excellent bcg.

Outstanding product . Had ejection issues with two other bolts read the reveiws, so i deceided to give kak bcg a try. I can fill the guys pocket with hot brass two lanes down now. You wont be disappointed .Plus shipping is super fast.

This BCG takes the worry out of all of the horror stories out there about AR10 BCG's not ejecting etc. I even run it dry and yet to have any stoppage with KAK's 12.5 barrel. I really can't say enough positive things about this guy. Along with the price, and quick shipping, look no further.

What can I say? I had built four AR10s that seemed to all have a similar issue. The brass would eject about one foot out of the rifle. And even after changing the ejector spring in all four BCG's there was only a minor improvement. The springs that were in the BCGs WERE weaker then the new ones, BUT they ejected about 2 feet out from the rifle, instead of one. Ok, they DID eject, I guess that was a good thing. BUT I was having issues on the last round int the magazines spinning around as they were ejecting and staying in the port area thus jamming the rifle. I read about these double ejector BCGs from one of the blogs and bought one, two, three and now four. Turns out I really don't need this one for the build I was going to use it on, BUT it will go on the 6.5 Creedmoor I put together. Great idea, that works. The brass now ejects about 6 feet away. That is where I want it to go. 1 foot is jut too close. Makes me think the rifle has issues...oh, wait, IT DID!

I am very happier with this BCG. The fit, finish and function are one of the best you can get. Very fast delivery and customer support. I would buy this again and recommend to anyone who ask.
