  • M4E1 Lower Receiver in Anodized in FDE Cerakote
  • M4E1 Threaded Assembled Upper Receiver in FDE Cerakote

M4E1 Lower Receiver Features:

  • Threaded Bolt Catch Roll Pin – Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (pin included).
  • Integrated Trigger Guard – Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger more rigid platform to build upon.
  • Upper Tension Screw – Allows users to fine tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.
  • Threaded Takedown Pin Detent Recess – Allows user to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw (no more launching detents across the room).
  • Increased Magwell Flare – Increased the flare of the magwell to aid in quick and efficient magazine changes.

M4E1 Threaded Upper Receiver Features:

  • New enhanced forging that gives the upper receiver a “billet look”
  • New picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
  • M4 Feedramps
  • .250 takedown pin holes
  • Lazer engraved T-marks

    Love the RECEIVER finish was a little light in spots

  2. Anonymous (verified owner)

    Great product, upper and lower have a tight fit, very good cerakote job.

  3. Scott (verified owner)

    Great price on a great product. Shipped very fast. Less than a week from placing my order to it arriving.

  4. Ben S. (verified owner)

    The cerakote application is smooth and even, but semi-gloss, rather than flat, like other factory-coated parts. Since its not flat, it looks slightly darker than standard Magpul FDE, but it’s actually just a hint darker when compared to Aero factory color. It won’t perfectly match most factory coated handguards, but it’s actually closer in color to FDE Pmags than factory-coated items. Overall, I’m satisfied, but will have to have a handguard coated locally to match the semi-gloss finish on this set.

    FDE coat had a few very small light spots as well as a small bump near the trigger guard. The upper and lower fit together very snug. Overall I’m happy with the purchase. Will buy from BK again. Thanks.
