Charlie's Custom Clones stocks barrels for the platforms we care about most: clone-correct M4A1 and Mk18 AR-pattern barrels, HK roller-delayed barrels for MP5 and G3 variants, FN SCAR-family barrels, precision bolt-gun blanks and chambered pre-fits, and hard-to-find service-spec profiles from Colt, FN, Daniel Defense, LMT, and Knight's Armament.
We prioritize barrels that match real-world military and law-enforcement configurations: correct twist rates, correct profiles (government, SOCOM, heavy, pencil), correct gas-system lengths, and the correct markings where applicable. Every barrel is checked for bore straightness and thread concentricity before it leaves the shop. Chrome-lined, nitride, and stainless match options are stocked depending on the role.
Whether you are finishing a Block 1 M4A1 clone, building a precision .308 gas gun, rebarreling an MP5 host, or sourcing a replacement for a worn-out service barrel, this is the category to start in. Not seeing the exact spec you need? Contact the shop — we can often source it direct from the OEM.
