KAK 308 BCG

Bought this to go in a Ghost Firearms build (all purchased from Primary as well). Everywhere else online, guys are swearing by this bolt carrier group, for the fact that it has the double ejector, and tends to work well (in hindsight, reviews across the web for this thing are about 60/40, in favor of the bolt group). <br>Upon putting it in the rifle, it looked, felt and just overall seemed like a good decision. As i got to messing around with it, and letting it slam into battery (lock with empty mag, hit release for test of function) it got stuck. <br>A few shop hours, and a couple hundred bucks later, my gunsmith informs me that the bolt itself had not been milled properly. He fixed it, and it's smooth as butter now. That being said, i'd have been better off getting a little more expensive, reputable bolt from the get go. Keeping it though, as it is now custom fit/function to my exact rifle.
Form, maybe Fit, bit not function
It looks well made. I however had issues with it from the get go. I have a dpms 308 12.5" barrel, slr rifle works adustable gas block and the jp capture / silent spring system... couldn't get relaible cycling. Borrowed a dpms 308 bolt carrier group from a friend... no issues. Shopping at PA for a carrier group now.

Nice and tight. No bolt wobble. Quality parts. Zero failures to eject. Runs nice and smooth after break-in. It will be stiff out of the package. A good sign. Lube it up and work the bolt by hand a hundred times.Then install and rack it gently a hundred times. Do a few full slams from bolt hold-open. Clean and re-lube. Check headspace. You're ready to shoot.
Worth the $$$
This KAK bcg replaced an AIM bcg. Since putting this in with its dual extractors, function and reliability are 100% in my rifle. Suppressed, unsuppressed, it just functions. I also like the black nitride for helping with function.
