Charlie's Custom Clones specializes in authentic Colt lower receivers — the most collected and clone-critical component in the AR-15 market. Our Colt inventory spans decades of production, from original LE-serial M4 Carbine lowers to SOCOM-contracted M4A1s marked "Property of US Govt," to Mk18 Mod 0 virgin stripped lowers from Colt's 2018 production run.
Every Colt lower receiver in our catalog is genuine factory production — not replica, not "clone-correct inspired," but the actual Colt-manufactured forging with original rollmarks. We carry stripped and complete configurations, including NOS (New Old Stock) examples with CAGE code and QR code verification.
Collectors note: Colt's lower receiver rollmarks changed across production runs — LE serial, CR serial, CAR serial, and SOCOM-contract marked pieces each have their own provenance and clone application. If you're building a period-correct M4A1, an NSW RECCE, or a GWOT-era Mk18, the lower receiver markings matter. Browse the full Colt inventory below and reach out if you need help matching the right lower to your build.
