    DPMS .308 Build

    Posted by Jorge on January 31, 2021

    Extremely satisfied with how well this barrel fit on my upper as well as how accurate it shot when I was zeroing my scope. (200 yards due to 20 MOA scope) 1st shot was dead center a inch off the bullseye and was easy getting my zero after that.

    Outstanding speed in getting my barrel to me during the busy Christmas season. Barrel came looking perfect. Very happy. Can't wait to do this build.

    KAK earned a new customer!

    Posted by Tyler on December 31, 2016

    Great service, sent a message about the product, got a reply in a matter of hours! Barrel shipped out same day and had it in a few days from that point. Have not installed yet, but from the sound of KAK stance on customer service and quality shouldn't be a problem. Barrel came installed with feed ramps and is stamped 308win 1-10, just in case someone wanted to make sure!

    This barrel functioned flawlessly in my PSA build. Accurate, inexpensive, attractive, and tight-fitting in my upper receiver.

    I bought this barrel for my Mega Arms MATEN 308 Build. Since I've been so impressed and happy with my other KAK barrels, I decided to try out the 18" Stainless 308 barrel. First off, the Fit and Finish is excellent. I went with the MKM Keymod (12" Handguard) so that it covers the low profile gas block on this mid-length gas system. The mid-length gas system was a definite plus because it will cycle anything. And not only will it cycle anything, it shoots PMC under an inch at 100 yards! Better than my buddy's LWRC! So super reliable (haven't cleaned it for 300+ Rounds so far) and it keeps impressing me with how accurately it can throw lead! Looking forward to hunting this year, get some blood on this pretty thing. Btw, Customer service is awesome, and super fast shipping... What more can you ask for?
