Description
This product is 100% Made in the USA! Our gas tubes, gas blocks and even roll pins are all proudly manufactured in the US. All Complete uppers are headspaced prior to shipping and test fired.
The BKF AR15 M4 MOD-1 Rail M-LOK series provides an alternative aesthetically progressive design that is lightweight with our 7075-T6 Steel barrel nut and attach method. The innovative attachment of the rail and the barrel nut provides a solid lockup, a seamless, strong joint that requires no timed alignment to the barrel nut itself. All BKF M4 MOD-1 rails (and receivers for that matter) are designed with pocketed cutouts to further minimize weight. In addition, BKF M4 MOD-1 rails offer QD mounting at the rear 3,6 and 9 O’clock of the handguard.

Great build, great customer service. They build everything to order so give them a few days to ship it. Once shipped it only took a couple days to get it. I’ve put a few hundred rounds of fmj and frangible through it so far with no issue whatsoever.

Wanted to wait on the review until it was built out and zeroed. Although I’ve only put around 260 rounds downrange- the quality is excellent and the main reason I purchased this upper was for the strong handguard lock-up. So far with midrange ammo, you can expect all rounds touching at 50 yards and easily a 1.5 MOA at 100 yards. Even using off the shelf “trash” ammo you can expect around 4-5 MOA standing at 100. Again, ammo dependent, but so far the quality you’re getting for the price is extremely hard to beat. Now I have this on a built out lower and decided to officially start the SBR process (Received approval in 3 business days doing eForm). So if you’re looking for a solid 12.5 upper, it’s really hard not to spend your money at BKF for sure. Extremely impressed and will continue to run this setup for the foreseeable future!
