  1. Colt Warren (verified owner) –

    This is an awesome upper!

  2. Chad H. (verified owner) –

    Very fast free shipping and exactly what I ordered

  3. Anonymous (verified owner) –

    Had a small problem with the feed ramps, probably just needs broken in, but had a few rounds that were getting stuck and scarred where the casing necks down. Tried a different lower and bolt and it did the same thing. Simple fix, just shoot it more and keep a reasonable amount of oil on it.

  4. Martin B. (verified owner) –

    Love the handguard… and the craftsmanship is amazing…

  5. NELSON RODRIGUEZ (verified owner) –

    Exactly as described and fast professional shipping.

  6. Stephen (verified owner) –

    This is a nice piece. Product was as advertised. Barely broke it in last weekend, but so far impressed. Will be doing more business here.

  7. Larry Parks (verified owner) –

    I am very happy with the BK Upper. I am waiting on the rest of the parts to complete the build. I am excited to take it to the range and shoot it.

  8. Michael J. (verified owner) –

    I received another example of your fine firearms for a fair price. Now as soon as the scope comes in, I will get to put it to the test of accuracy.

  13. Alan B. (verified owner) –

    I liked it so much that I bought 1/2 dozen of them. Well made & very accurate. The price & shipping are very good.

  14. dema983 (verified owner) –

    Owned 4 years now. Running with the BKF trigger and lower parts kit. It’s a very accurate, tuff, versatile setup. Has been slung all through the TN mountains in all weather conditions and has never failed me in any way. Confidence in BKF has brought me back for yet again another upper purchase.
