KAK 9MM ENHANCED BCG

Solid BCG, would purchase again.

Bought this for my PSA AR9 upper, initially I only went with KAK’s conversion to 9mm magwell for my AR15 lower, but found that PSAs BCG didn’t like my Colt mags, nor the the feed ramp that comes with KAK’s magwell conversion as it was tearing up the casings and projectile heads of my subsonic rounds; leaving fine metal shavings all over the internals. Ammo in good shape dry cycling a magazine with this BCG, no notable deformations. Previously, couldn’t insert magazines without the bolt to the rear, now I can with a firm press. Perfect for amber conditions. I’m sure it’ll perform just fine at the range. If not, a heavier buffer tube probably from these dudes will finish the job.

This 9MM AR BCG worked perfectly for my post sample mg. As always KAK products come through and at a great price!

I have firearms out there with over 20,000 rounds thru them and counting. One failure ever was due to ammo. These are built to last.

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.

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.
