Colt 14.5" SOCOM M4A1 "Block 1"

This is a vintage upper, 14.5" with Colt factory pinned and welded barrel, with Colt style extended A2 flash hider.

This is factory direct from Colt.  Limited Supply.  Hot Seller

The barrel is pinned and welded by Colt, overall barrel length is LEGAL at 16.1”. New factory Colt M4A1 Complete Upper with Block 1 features and possibilities for a Block 2. Colt factory pinned 14.5” SOCOM profile barrel. You do not see this often at all. YAHOO !!! Shout it louder.

"Street legal" factory pinned barrel from Colt, 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. This is a take-off from a Colt factory rifle.

The upper comes with Complete with a KAC 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 factory upper, with the upper receiver, barrel, FSB, all being factory timed and installed Yes, bolt, barrel and upper receiver all have Colt markings that you would expect.*

Take a look at the pics. The Matech has the new Picatinny Engineering logo/marking on the right side. Colt calls this GI Issue. Technically yes, but most of us might expect no markings for USGI. This is how Colt shipped it, so I want it to as pure as Colt shipped it.

The Upper comes with a mil-spec M4 RAS quad rail. Some earlier rifles and their uppers shipped with the Troy rail, but you should not be confused with that model. That model was a commercial release and had a standard 16” 6920 barrel. This is a military rifle upper, with the flash hider pinned. That is the only part that is civilian. This is a great military M4A1 upper. Your upper (here) has one has a mil-spec M4 RAS. Keep in-mind that some parts of the RAS are new old stock, and some of the rails have shown some age, as well as being dated old, when you turn them over. Some have some minor scratching. I think Colt went into their military surplus pile and added these on. Nothing wrong with that!!!

Note:  This is the from the limited release 2018, 2019 and 2021 rifles.  Do not confuse this with an HBPW or other newer or older releases.  This release has all the bells and whistles, ready for battle.  This is released off the military line, so don't expect a perfect finish.  Be prepared for battle scars, or beauty marks from handling.

--- Colt military grade upper receiver, 7075 aircraft grade aluminum with military grade Type 3 anodizing and with Cerro Forged marking (keyhole), with no CAGE code marking.  This is how the upper came from Colt.  If you want a CAGE code upper, we do swap that for an additional fee and shop time.

Note:  Picture shown with standard pinned A2 barrel and Colt side sling swivel.  If you want the barrel without a flash hider pinned and welded, just let us know in the comments section when you check-out.

Consider an optic with your upper -- EOTech red-dot, Aimpoint M68 red-dot or the Elcan 1x/4x Specter with your upper.

Note:  Charlie's also stocks an FN upper receiver assembly that is technically the same upper, but made by FN, another great defense small arms manufacturer.  See here

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.
