Colt M4A1 SOCOM Block 1 Upper Receiver Group
with Milspec M4 RAS and vertical grip; pinned and welded 14.5" Colt SOCOM barrel
The barrel is pinned and welded, overall barrel length is LEGAL at 16.1”. New Colt M4A1 Complete Upper. Standard Extended A2 flash hider and Colt 14.5” SOCOM profile barrel.
"Street legal" pinned flash hider, makes this item legal to own without an NFA tax stamp. A few surface scratches, which, if you buy new Colt, you know are common. This is a highly desired and sought after upper.
The upper comes with Complete with a mil-spec M4 RAS handrail with 3 KAC ribbed covers, Colt heavy profile SOCOM barrel (standard SOCOM with M203 cuts), Matech GI issue rear BUIS and genuine Colt complete BCG. Still heavy with Colt factory oil, not shot since factory testing. This is a new upper, with the upper receiver, barrel, FSB, and the front sight base has been timed and installed by Colt. This is an "F" height FSB, although Colt is not marking all FSBs with the "F" Yes, bolt, barrel and upper receiver all have Colt markings that you would expect.*
--- Accommodates the full range of 5.56mm ammunition, including the NATO M855/SS109 and U.S. M193, as well as longer-range ammo like the Mk262 Mod1 77 grain, preferred for SOCOM operations, utilizing a rifling twist of 1 turn in 7".
--- Colt mil-spec cage code stamped 14.5-Inch 1/7 twist 5.56 NATO chrome-lined MP tested barrel with factory tuned and professionally pinned front sight base (FSB) with bayonet lug and an option for a sling loop swivel. This upper comes with no front sling swivel. You can add one here. Note: comes standard with pinned extended A2 flash hider, so not an NFA item. Charlie's uses a standard extended A2 and we send the pinning and welding to a professional barrel shop, who does outstanding work. Much better than the older Colt A2 extended flash hiders with rather unsightly weldings. If you wish, you can ask for no flash hider on the upper, and upper will need to be mated with a lower and registered as short barreled rifle (NFA), or you can build a pistol with a legal lower and brace.
--- Colt M4 upper receiver with M4 feed ramps.
--- Complete Colt M16 Full Auto Bolt Carrier Assembly is standard. All the normal markings on the bolt. Carrier will not have a "C" mark, as Colt is phasing out the markings on the carrier, but still has the "MPC" on the bolt itself.
--- Mil-spec P&S M4 "quad rail" RAS with two Knights Armament 11- rib full size rail covers and one short rail cover for the bottom rail, to fit the VFG. Note: P&S RAS and Knights RAS are identical and both are contracted for the M4 rifle. Typically, we can source P&S at a lower price, and pass that savings on to our customers.
--- Backup rear sight: Matech USGI 600m rear back-up sight (not Picatinny marked)
--- Colt Mil Spec Charging Handle.
--- Knights Armament VFG (vertical forward grip) included.
Note: Standard configuration is NOT an NFA item. If you choose the unpinned barrel, all NFA laws will apply.
Note: All ITAR regulations apply. Charlie's deals in the real McCoy. Your item most likely has parts that cannot be shipped outside of the USA, or owned in the USA by non-US Persons. You take accountability to safeguard parts and the entire upper, and get necessary approvals to transport outside of the USA.
* Some Colt uppers are being shipped with the front sight base (FSB) not being marked with an "F" and the bolt carrier not being marked with a "C." All upper receivers have the Colt CAGE Code and all bolts are marked "MPC" like you would expect.
