AR10 BCG- Dual Ejector Bolt

I was looking for a better bcg for a kit build from other manufacturer. The one that came with kit would not feed reliably. I thought I would give this KAK bcg a try. I was very impressed. It is well made with innovative twin ejectors. Functions flawlessly. I wish all manufacturers took such care and pride in their products as KAK does.

The bcg arrived in a timely manner and was packaged very well. Upon opening the visual quality was impressive and it installed with out any problems. Haven't had the opportunity to test fire yet but as soon as I do I will up date the review.

I purchased this bcg for a .308 build. so far I have shot 180 rds thru it. No malfunctions or fte`s.. Smooth ejection at 3-3;30. I do believe that the double o-ring on the extractor is a bit much. I think to test this theory I will run 200-300 more rounds thru the gun to loosen it up and take one o-ring off. The double o-ring is not hurting the brass and is a good idea till the gun breaks in. But I would like to test this later. For the price this bcg is A++, would buy this again in a heartbeat . The machine work and the finish is first rate. I have seen worst for a lot more money. ( name brands ) If they can keep the price and quality as it is today, I will buy more for my future builds. I took a chance on this, and I`m glad I did.

Used this to finish of my 308 build, I used both the 308 Lower parts kit and KAK LR-308 BCG DOUBLE EJECTOR (BOLT CARRIER GROUP) MP. No problems at the range last weekend breaking in the new build. Very impressed Will use this product on my next build. The upper I was using was a DPMS oracle upper.

I'm running this in a PA-10 SBR configuration with the KaK 10.5 barrel with an adjustable gas block . This bad boy zips thru rounds like a rat does cheese. I was skeptical about the overkill of this BCG. Rock 'n' roll baby !

Purchased two of these for a couple of projects and just wow! The finish and quality looks to be better than I imagined ! Fast shipping and great communication on KAK's part ! I'm looking forward to my next purchase! Thanks KAK!

I have not completed my PA 10 build yet, so I do not know about the operation yet but I received my order fast, in good packaging, and bottom line, it looks amazing! Sold built, great quality, and a killer look! Can't wait to finish the build.... And order more from KAK!

Years ago I bought the Remington R 25 in 308 (DPMS LR308) and quickly learned that it was extremely prone to FTE, stove piping and double feed. This would happen about every third shot. Over a period of years I added 'O' rings to the extractor spring (helped a little). I bought the DPMS upgraded extractor with elastomer tensioner (helped a little). I upgraded the ejector spring with an enhanced spring from one of the A+ spring makers (helped a little). But, nothing I did came close to making the rifle truly reliable. I found and bought the KAK BCG with dual ejectors. The next trip to the desert found the R 25 able to digest 150 rounds of various ammo (NATO spec, heavy for caliber) like a well oiled machine. It was flawless. Every pull of the trigger saw the brass kicked to the two o'clock position about 12 feet away. It did not group then neatly but it darn sure got them out of the chamber and either chambered the next round or locked open on last round.. SUPERB PRODUCT.

Outstanding product!!! Placed it in my Aero M-5, perfect fit. Have already run 500 rounds of 147 grain NATO without a single hickup... KAK has a winner here!
