John Norrell Colt 636-style "DEA" 9mm Integrally Suppressed Upper Receiver w/ patch & DEA Manual (reprint) - $3500 WITHDRAWN
This upper is a very unique and rare John Norrell Colt 636-style integrally suppressed 9mm upper receiver. This upper/suppressor assembly is from the early 90's and is made in the style of the original Colt/KAC integrally suppressed 9mm upper which were used by the Clandestine Lab Enforcement Team (CLET), seen also in the Max Crace painting from the 1980's, “Knock knock." The upper receiver itself is a small pin Colt 9mm SMG receiver (originally came to me on a large pin sporter), with a standard full auto 9mm bolt and matching charging handle. The suppressor is a two stage design that works similar to an MP5SD. An original 10.5" 9mm SMG barrel was heavily ported, then a large expansion chamber and packing material surround it. Finally a small, traditional cup baffle suppressor is in front. This causes even standard supersonic 115gr 9mm ammo to leave the barrel at subsonic speeds. It's easily one of the quietest semi-auto, center fire I've ever shot. Upper will come with the reprinted DEA manual which includes references to the upper and a CLET patch. THIS IS AN NFA ITEM. Currently on a F4 in MI. FULL ALBUM
Colt 604 Upper Receiver, very early and factory original - $2750
This is a very early, complete 604 upper receiver that I believe to be entirely factory original. The upper receiver itself has all of the original forging features that put this in what was likely the first batch of 604's made. Near the ejection port in the upper right corner, it has the square pad area, and more importantly, just below the left side of the ejection port, the body line which extends up from the magazine well on the lower is in the original location, positioned directly underneath the port instead of to the side, meaning that the line from the edge of the magazine well on the lower matches up with the line on the upper. This profile was changed early on and now all current uppers have a step between the upper and lower as that profile was moved left to add more material in that area. The front lug is also rebated. The barrel is M VP marked with 12 at the 6'clock position by the muzzle. The exterior of the barrel has patina but the bore is good condition and not pitted out like most Puerto Rican import uppers. No drain hole FSB with forge flashing remove, roll pin front sling swivel and early bend style gas tube. The bolt is the correct transitional slick-sided with all phosphated parts but a chrome gas key. The firing pin is the correct flat-head. Handguards are also the correct, early no drain hole type in good condition. The receiver itself is sunbaked with a lot of the original anodizing faded and missing in some spots near the front.

Colt M16A1 parts kit rebuild with 1969 Colt barrel - $1700
This is a complete Colt M16A1 upper receiver in good surplus condition. The upper/ejection port door/slip ring/charging handle/BCG all came from a surplus parts kit, to which I added a 1969 Colt M16A1 barrel. Barrel is marked C MP C, has a drain-hole C and Bell marked FSB with forge flashing removed. Bore is in nice condition, no issues to note. Handguards are nicely mottled and have drain holes and L/R markings. BCG is stamped C and bolt MPC. The upper is likely early 1970's. FULL ALBUM
Colt 741 HBAR - factory original, perfect condition - $2750
A very hard upper to find, this is a factory complete Colt 741. This is not an HBAR sporter which was converted with a bipod but a very early 1980's factory upper. Receiver is marked C M for Marietta forge which was used for the first few years of A2 production in the 80's. The forward assist is a clipped large button to be used with A2 lower receivers. The BCG is stamped C with the bolt marked MP C. Another very rare early A2 production feature is the unmarked heat shields in the handguards. The barrel is an HBAR profile, but the tell is the position of the markings. In front of the FSB, the barrel is marked C MP 5.56 NATO 1/7, but is shifted closer to the FSB than on normal A2 uppers so the text isn't cut off by the installation of the bipod. Sporter barrels are marked HBAR which this is not, and if made from another A2 barrel, the barrel stamping text will be cut off when the conversion is done. Factory mounted bipod collar is installed with an original Colt production bipod which are very difficult to find. Overall it is in very excellent original condition and appears to have been shot very little. Parkerizing on the barrel is a nice deep gray with a very nice 80's Colt Gray on the upper. FULL ALBUM
Colt 750 LMG Upper Receiver with hydraulic buffer, action springs, LMG bolt catch and manuals - $4200
Last but certainly not least is a factory original Colt 750 LMG upper receiver. This is in excellent original condition and waiting for your transferable or post sample receiver (or semi!). Included with the upper is the correct hydraulic buffer and 2x green action springs meant to be used with it. Also included is the correct LMG-style bolt catch. This is intended to be used with the open bolt FCG to allow the bolt to advance forward from the catch to the sear engagement on the underside of the BCG when the magazine button is pressed. This makes the gun ready to fire when the next magazine is inserted without needing to press the bolt release. It can be used on a semi-auto lower without issue however and is a nice touch to a semi-auto clone. The BCG/bolt are standard Colt stamped M16A2 and does not have the sear cut on the underside. Also included is the small green factory user manual as well as a the operators and maintenance manual. FULL ALBUM
