  23. michael (verified owner)

    Item was shipped and received quickly considering the surge in orders and post office being slow. Haven’t used the BCG yet as I have been waiting on other parts. Finish looks great and even. The bolt is MPI labeled. For the price not sure if you can beat it especially since PSA keeps increasing their prices.

    Even though this a complete budget pistol lower I used it to mate up to BKF complete 300 Blackout 8″ upper, BKF standard M16 BCG no logo, a Warhammer Mod 2 charging handle and BKF Ar15 Nickel Teflon Reduced Power Fire Control Group – Complete (Polished) (3.5lbs-4.5lbs).

    The fit was perfect, there was no slop in upper and lower halves. The trigger assembly was smooth. I shot about 100 rounds without any problems. Was able to sight in my red dot at 25 yards using remanufactured ammo three shoot group with dime hole results from a bench setting .

    I was able to duplicate the results 4 times. I am more than pleased with the quality of BKF products would most certainly recommend to anyone wanting to build a quality AR. Also quick delivery on the shipping. I have no affiliation with BKF products what so ever.

    These guys are top tier, they test everything before sending it out. Glad they did, the original bolt carrier was defective. They notified me and swapped it out for a proper working one. Top quality products for great prices and amazing customer service. They will be my go to for future projects.

    Perfectly good BCG, 100% as good as any I’ve got from other vendors in the past that charged more (in fact, I’m 99% sure it’s the same OEM I’ve gotten elsewhere)

    very good BCG at a great deal! the gas key bolts are staked very well, no worry about them coming out lol. I will order another for my next build for sure. You cant beat the price. Took it out ran 500 rounds through the complete BKF upper I had them install with out a hiccup with very good accuracy considering I was only using 855/M193.

  61. Daniel C. (verified owner)

    As soon as I got it installed I ran 500 rounds through it. Functionally was perfect! Staking on the gas key is second to none and you won’t beat the price. This will be my go to BCG!

  62. Gary B. (verified owner)

    You’ll be hard pressed to find a BCG of this quality at this price. The “other guys” are charging $30 more and higher. Yep, I’ll keep buying BKF!
