KAK 9MM ENHANCED BCG

Functions as advertised second one ive purchased used in integ silenced fire arm.

I purchased this bcg for the epc9 I was building, because the aero precision bcg was out of stock. I was hesitant to buy wondering if it was going to function. needless to say it works perfectly. since then I have bought another one. I recommend getting this bcg for your epc build.

The bolt is amazing, the fit, the finish, the operation, everything is excellent, the only thing is that it does not work in full auto lowers, the hammer does not go down enough for the auto sear to engage

Details: • I had this BCG before Aero Precision fixed the feed ramp issues on the EPC 9 Barrels. It ran the cartridges through like a charm, from the 27 round Magpul Glock Mags that Aero sells. • After I screwed up the barrel, I did have one cartridge to explode on me, but that is because I made my own "feed ramp" that allowed way too much space tp pressurize the back of the bullet. The Kak BCG however, held it's own and suffered no damage. • I have since gotten two Aero Precision EPC 9 Barrels with the corrected ramps, and run the KAK BCG on one that is about 8 inches and on that is shorter with a suppressor. • Hands down, the KAK BCG runs everything solidly and I have not had any issues whatsoever. • I will be purchasing another KAK BCG once I get a lower for my suppressed upper. You will not be disappointed. Go with KAK.

Bought this to use with a colt magazine pattern ar9 and works flawlessly. Only had one problem which was a weak firing pin (could've been a factory defect). The firing pin broke after 3 magazines, but KAK replaced the pin in 4 total days. Fantastic service and the BCG has worked perfectly for over 1000 rounds after the replacement so far. The service alone is worth getting the BCG, but overall a great product from a great company.

Excellent design and flawless execution. I am a retired law enforcement officer, turned machinist and gunsmith. To say that I notice every detail would be an understatement ! Machine work and finish are superb. The key is properly staked and the threaded retention pin for the AR15 pattern extractor is a cleaver touch. Perfect function with Colt pattern lower receiver.

Paired with the KAK 16" 9mm AR barrel, work 100% so far. Will get another one for sure.

Excellent built just what I was looking for

I have built numerous 9mm AR15s and consider this the best BCG on the market. Both of mine weigh in right at 15.45oz so thw weight is a little heavier than some and a little lighter than others. Love the standard AR15 extractor feature, makes more sense than the 1911 style some use. This BCG also works without and modifying to my Mean Arms Adapter. That can't be said for some 9mm BCGs I've tried. Price isn't the cheapest but I've had to send some of the cheaper BCGs back. I prefer quality and so far my two KAK 9mm BCGs have been flawless. Same with the 40 cal and two 45 cal versions I have.
