Purchased (2) of these completed uppers from BKF. I am very pleased with the quality of assembly and accuracy from both units. Looks like I found my new favorite vendor. Hats off to BKF for a great product and customer service.

Product shipped quickly, arrived blemish free and as advertised. Will absolutely not hesitate to purchase another BKF barrel or upper.
Matt Orr (verified owner) –
Awesome experience purchasing from you guys, still working on the build to see how the upper runs. My only concern cuz I’m picky is just making sure that the barrel is clocked right which I don’t have the tooling for

I will take BKF uppers over BCM any day. I’ve put north of 5000rds through my other 11.5 and 12.5 and 14.5, never had a hiccup. These barrels are so accurate. Nothing is over gassed and it runs all the ammo I put through it. LE, civilian, buy these uppers. They work so well. As long as prices stay the same I’ll continue to buy & refer others to buy as well.

First time ordering from here. Purchased this upper on a hunch during Black Friday after doing some research reviews and I must say I’m absolutely blown away with every aspect of service, from shipping time (very fast) and quality of the item’s ordered. TOP NOTCH! Perfectly gassed. Cycles/ejects everything I feed it all while being an ever so soft shooter. Accuracy was dialed in straight from the box. BLOWN AWAY by the quality and am now a customer for life. This is my new “go to” going forward. Thank you so much for such a pleasant first purchase! I will be back!
