PLEASE READ-----Up for auction is a New, Unfired, custom built Colt M4A1 SOCOM upper. The barrel is a Factory Colt M4A1 (not standard M4 ) 5.56 NATO, C MP, 14.5" SOCOM-M4A1 barrel with a Permanently pinned and welded Micor 1/7 model flash hider to bring the total length out to a legal length of 16.125". You can slightly see the welded pin in the picture with the arrow. Get the true M4A1 look without the SBR paperwork. The Micor flash hider is specially slot twist calibrated to a 1/7 barrel (as stamped) for increased accuracy, reduced recoil and reduced flash. It is manufactured from a 4140 alloy and has a melonite coating. The flash hider is Mil-spec and has a notch in the bottom for a blank firing device and will accept suppressors that will mount to a standard A2 flash hider. The Bore is a chrome lined, magnetic particle inspected, with a 1/7 twist. Perfect for 62 SS109, M855, 65, 68,69,75 and 77 mk 262 and OTM type ammo. Has the military M203 factory flats. The front sight has been professionally shaved to fit under a free float Rail. The gas tube is a WMD Nitromet Carbine Gas Tube that is a Mil-Spec stainless steel gas tube that has been salt bath nitrocarburized for extra resistance to heat and corrosion. The Nitromet finish gives added durability and surface hardness for improved corrosion resistance and a longer service life as well as reduced shine. We also added a custom copper coil heat sink to the gas tube to reduce gas tube temperatures. Barrel comes with the factory Colt barrel nut. Note: you must use a rail that uses the factory nut such as a Troy, Samson, Daniel Defense omega, Midwest, etc. The upper receiver is a Forged Mil-spec upper with "T" marks. It is a "square" forge marked upper (Brass Aluminum Forging Enterprises LLC). The same ones Colt is currently using on there new guns. We built this for a customer, but he was unable to full fill his obligations. So, we are selling the upper for cost of parts, assembly, machine and welding time only. No more. (At the time of writing this we have this upper and one additional barrel listed) Comes as seen. No handguard rail, bolt carrier group or charging handle. Add you own custom ones.
