with official NSWC Crane markings, M4 Carbine marked

Limited Production Colt M4 lower receiver with mk18 Crane Logo

This is a factory Colt receiver – superior quality with custom MK18 Crane logo.  FN, LMT, Colt, Knights Armament make rifles for the US Military.  When it came to the Mk18, Colt M16s were first used by the US Navy, and now you can own a Crane Mk18 Mod0 Colt lower.  This is a customized Colt lower, with the Mk18 Mod0 Crane logo for your Mk18 build.  Factory Colt lower (not eligible for a pistol build), with customized engraving on the left magwell.

Charlie’s has researched the original Mk18 Mod0 Crane issued rifles, and has worked to find the period correct logo, and commissioned the engraving on this high quality lower receiver. We have a number of different Mk18 and Colt lowers, and we try our best to be very specific with each lower receiver, as we know that many Colt clone aficionados treat every marking on a Colt like a vintage of wine.  You can get a little too OCD, but we will keep you balanced.

Features:

  • Colt Forged 7075 aluminum semi-automatic factory lower receiver
  • Hardcoat anodized – military grade spec
  • This is a Colt, expect handling marks, maybe a small scratch.  All part of the character.  Colt is made for the military.
  • Compatible with Mil-Spec AR-15 and M4 lower parts
  • Precise tolerances
  • Perfect for a rifle build (this is a take-off from a full Colt rifle, so a pistol cannot be built with this)
  • 2020-2022 era M4 Carbine, CR serial number with QR code.  The photos of the left and right sides of the receiver are actual items we are selling, so expect that.  These are typically laser engraved.
  • Custom engraved with historically correct NSWC Crane logo exclusively for Charlie’s Custom Clones
  • Serial Number Series:  CR
  • QR Code:  Yes, on magwell 
  • Virgin Lower:  No, rifle take-off (cannot be used as a pistol)

Collectors and clone enthusiasts alike will appreciate the true M4 Carbine markings on the lower.  This is perfect for a Form 1 SBR build.

Charlie’s has maintained and inventory for customers who want this type of lower, and we buy in the open market from other dealers.  What is highly valued is the M4 Carbine marking, which is preferred for military correct builds.

Charlie’s Custom Clones had the lower custom engraved with Crane Mk18 Mod0 logo.  It may seem easy, like everything we do, but our team actually spent hours researching the correct logo and not just any markings, so you will have the real deal Mk18 Mod0 logo, and can build a rifle, and SBR (with proper registration and engraving).

Charlie’s also offers the Mk18 Crane logo complete lower receiver from FN.  If you are interested in a complete pistol, with the LMT lower, take a look at the Mk18 Mod 0 LMT Custom CQBR Pistol Kit
