KAK ENHANCED 45 ACP BCG - TUNGSTEN

Assembled the rifle and went to the range. First three rounds had one FTF. Disassembled and added more CLP.. Next three fired fine. Loaded a full mag and shot flawlessly....my new favorite rifle!

Bought this to replace a BCG that had a lower lug and failure to feed issues. It took about 4 rounds to break in and has been 100% reliable. I especially like the larger extractor.

put together a 45acp pistol with brand X bolt and would not function correct, Ordered a KAK bolt replaced brand X bolt and pistol works plain and simple KAK knows what they are doing! Great products and dang good quality, Thanks KAK

I appreciated having the pinned weight inside of the carrier directly rather than using heavier buffers. I think this is better for several reasons, mainly due to how blowback action works making the bolt itself heavier rather than having to tune the buffers and springs to get it working right. Since I didn't use a LRBHO lower, overtravel isn't a concern breaking off bolt catches. I ended up using an ARstoner (midway house brand) billet 9mm/45acp upper. A 308 carbine length buffer spring and an h1 buffer. I have perfect 3 o'clock ejection landing about 7 feet away. This is with mild 45acp loads. It's also great that it uses STANDARD 308 extractors which makes life a lot easier if you ever have to replace it so you don't have to modify your own or try to find a modified one in stock somewhere. The design is great. The finish is great. The machine work is great. It's well worth KAK's sticker price for them. Using 26 round glock mags. I have only had one failure to feed which nosed into the outside rim of the barrel. That was on the first round that I tried to put through the gun. It hasn't happened since and may not have been related to the gun and could've just been the bullet itself in how it was seated in the mag or maybe with the mag being new and maybe having a plastic burr or something. I don't know. But, it hasn't done it since and I've really been enjoying shooting it. Couple hundred rounds so far. Another reviewer mentioned that it was as soft shooting as their 9mm upper; I can agree with that. With the bolt being heavier than normal, and not requiring stupid heavy buffers, even feels better than shooting my old Tommy gun if you want to compare it to that. Thanks KAK.

I put this bcg in an eld performance 45acp upper. I put this upper on a new frontier ar45 specific lower outfitted with a shock wave buffer and blade. I'm using a 26rnd Glock mag. This set up works great the only issue I have had was the Glock mag if I put more than 20rnds it won't feed properly. I have mag dumped looking for a jam and found none. Coupled with the kak 3" flash can this setup looks great and Rus even better. Thank you kak I could not be more happy!

Couldn't be happier! High quality at a great value. KAK even offers mil/leo pricing on top of their already great pricing. My bolt now lives in a Gibbz side charging upper and runs like a sewing machine with my Glock magazines. Paired it with a 10 oz buffer and 308 extra power recoil spring. Just as pleasant to shoot as any 9mm PCC if not more so. Have run it suppressed exclusively through the first 100-rounds, and it has been 100% reliable. The heart of the build is a KAK bolt and barrel, stop shopping around and just buy KAK already! Seriously couldn't be more happy with how this build turned out. Thank-you KAK!

This thing is a tank. It is so awesome. I teamed this 16oz BCG up with a Gibbz side-charge upper and 8oz buffer with an 8" barrel. Right out of the gate it cycled like a dream. Thanks to the great customer service, my AR45 pistol Is no longer a dream!

The .45 ACP BCG mated up fine with an Aero Precision XL upper receiver and a Pantheon Arms Dolos system, plus an SB3A Tactical brace. I also used the .45 ACP KAK barrel and flash can/crush washer to complete the build. I also used a "Spartan" lower receiver, which was a bit of a challenge getting Glock magazines to fit...Mag modifications were required. The firearm has not been tested as of yet, but I don not anticipate issues other than buffer weight.
