    This lightweight barrel is great. It works great so far with my Aero upper with a JP adjustable gas system and a KAK AUG style flash hider. I would purchase again.

    Excellent Hybrid Barrel

    Nothing bad to say about this barrel. Value-Line KAK products are simply good priced items with no reduction in quality. Pay a third of the price and get the equivalent of a Faxon Gunner series barrel.

    Excellent quality at affordable price

    This is my third KAK barrel, and as usual is excellent quality. I considered barrels from Fa*** and B.a*******, but having had barrels from KAK before, decided to buy this 16 inch lightweight instead and was NOT disappointed. Accuracy is excellent, no loss of accuracy when the barrel heats up, barrel fit perfectly in an Aero upper, M4 feedramps were perfect, no burrs, clean rifling, clean crown, and barrel finsh is uniform and nicely nitrided. This barrel balances beautifully. Highly recommend this barrel.

    Always love ordering parts from KAK. These barrels made a great addition to two builds. Really nice weight and balance. Will definitely be ordering more for future builds.

    You can't beat it

    I am very impressed with the KAK's value line barrels. This pencil profile is lightweight and very accurate. I have use the Faxon 'Gunner' barrel for lightweight builds before but this barrel is as good as the Faxon and 1/3 the cost, what a deal. All of the products I have bought from KAK are great, no problems, some of the best parts out there. This is a great barrel and you will love it and love the deal you get at KAK.

    Great barrel for the money and love how light it feels when shouldered

    Picked up for yet another build and got it to the range today. Given my old eyes I am quite pleased being able to center hit the 3" 'head stump' on my IPSC steel target at 100M without fail, magazine after magazine on a hot barrel. Really like the profile of the barrel, felt lighter than it actually is due to how the profile changes for the forward pencil profile. Very similar to a Faxon 'Gunner' barrel we used to build a lightweight build for my son (but with an affordable .750 gas block!) but at a bit less than 2/3 the cost. Once again I am impressed with the bang-for-the buck you get with KAK's value line barrels. I may need to pick up another of these for my wife, she'd really like how light the muzzle feels. Great work, guys!
