Colt AR-15 9mm Carbine with Installed X-Ring Custom Auto Sear -A) X-Ring Custom Auto Sear, Registered Transferable Class III/NFA Machine Gun -
202
Serial no. XO-109, 9 mm , black finish. Manufactured
and registered prior to 1986, this M-16 pattern auto sear has been installed into a Colt AR-15
9mm carbine to make it capable of fully automatic fire. A pin hole has been drilled into the
fire control unit pocket to install the needed support, and the right side of the
lower receiver has been marked with the address and serial number of the sear. As
currently installed, the markings on the sear itself are obscured. Note that the text
of the tax stamp describes this sear as permanently installed in the AR-15 in this lot; it is not a
“drop in” component, and can not be installed in an AR-15 without modification to the lower receiver.
CONDITION: Excellent, with light wear. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered
with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.

AR15 9mm carbine that was reconfigured to act as a host for the X-Ring sear. Post front sight and two leaf rear sight with windage adjustment, bird cage flash hider,
bayonet lug and ribbed round handguard on the barrel, and the standard Colt markings on the left side of the receiver. The right handed selector switch is marked “SAFE”/”FIRE”/”AUTO” on the left side and “0”/”1”/”A” on the right. Slight adjustments have been made to the bolt to properly accommodate the full auto hammer and interface with the auto-sear. Fitted with a checkered pistol grip and a three-position telescoping buttstock. The extra barrel assembly is configured similar to the current one, though in 5.56mm with an 11 inch barrel. Magazine not included.
CONDITION: Very fine as converted to full auto, with 98% of the original black phosphate finish, showing some light handling marks, black touch-ups in traditional areas like the bolt catch pin, and a small amount of spotting. The furniture is in equal condition, and the extra barrel assembly shows some mild spotting. Mechanically excellent. NOTE: The lower receiver has been permanently modified to act as the host for the X-Ring sear.
Provenance: The Dr. Robert Azar Collection.
