Description

NEW FROM BKF! Designed from the ground up in a collaborative effort with some of the most up and coming names in the industry, the all new “M4 MK1 Comp”. This beautifully nitride coated muzzle device sports a slim profile, providing significant weight savings compared to its competition. The porting was designed specifically to greatly reduce felt recoil and muzzle rise, allowing for faster follow up shots on target. These features, coupled with very competitive pricing, make for one of the best bang-for-your-buck muzzle devices on the market.

  • Extremely high temperature resistance to handle full-automatic fire
  • Slim, unobtrusive profile
  • Durable high hardness nitriding process, yielding hardnesses up to 54 HRC
  • Top gas ports practically eliminate rise
  • Hybrid muzzle attachment, eliminate both muzzle climb and recoil
  • Virtually zero gas blow back due to 3 port flat face design
  • Proudly made in the USA
  • Machined in one operation, no error is introduced from repositioning in multiple setups
  • Nitrided by H&M increasing the 4140 CMV hardness

    Another nice piece from B.King! No tool marks, nice shiny finish. I haven’t tested it yet, but I’m certain it’ll do it’s job just fine. Plus, it looks better than a plain old flash hider.

    Easily installed, nitride finish wipes clean, better than expected muzzle rise and recoil control.

  8. James McCoy (verified owner) –

    Great looking muzzle! Insane bang for the buck! Came in perfect condition, spun it on, locked it down, and bang bang. Love it!

  9. Kim W. (verified owner) –

    Excellent finish. Nice looking brake.

  10. Miguel (verified owner) –

    Great looking muzzle device with a quality feel/finish.

  11. Victor S. (verified owner) –

    Little to no felt recoil as rifle was laying on rest..but deeper “boom” in shooting lane…fairly easy to align

  12. Patrick k. (verified owner) –

    Looks good. Fast shipping

    I have never used a device on an AR like this before, I have installed it on a B.King finished 12.5″ upper. I hope to get a chance to shoot it this weekend. I mated this upper to a finished PSA braced pistol lower with a Sylvan Arms gen 4 folding adaptor. Quite a set up. Hopefully the muzxle device will not be obnoxiously loud.

    Shipping, payment, delivery went as it should. When you search for the product, it lists it as $20ish and when you try to buy at that price, you discover that the piece at that price is for a finished upper. To buy it separately, it is $25ish. I had bought my finished upper about 2 years ago, so the lower price offering did not apply.

      This is because when you remove the flash hider to replace it on completed uppers, it makes up the $5 difference cost of the flash hider we swap it for.

    You can feel the difference in recoil from your traditional flash hider. A good product.

  28. Steven (verified owner) –

    Hard to beat for 25$. Finish is excellent and threads are cut well.

  29. Daniel C. (verified owner) –

    Used this on my wives build, haven’t shot it yet but the machining is spot on. It’s similar to several other 3 port brakes out there at 3x-4x costs. I bet it works exactly the same!

  30. Anonymous (verified owner) –

    Looks great on the muzzle.
