Colt/Diemaco AR-15 A3 Tactical Carbine

[OK Corgi Rancher]

Finally got my hands on a Canadian-made Colt. I already have a nice Canadian lower (complete), but now I have another complete gun. This was likely shipped to a law enforcement agency here in the states and somehow made it's way on to the commercial market.

Aside from saying "Made in Canada" on the lower it has the Diemaco/Devtek "D" on the upper receiver and the bolt carrier, "MPD" on the bolt.

Cool stuff for Colt geeks like me.

Looks like a dupe of my Colt Lightweight Patrol Carbine unless the straight profile is heavier. Nice rig for those not tying grenade launchers to barrels, why carry that heavier barrel out front if not needed?

The barrels on the A3 Tactical Carbine are heavy profile under the handguards. The M4 style rifles (with the grenade launcher cut) are the thinner, gov't profile under the handguards. Some people say the A3 Tactical Carbine is one of Colt's most accurate rifles and credit the heavy barrel for that as it supposedly dissipates heat better or doesn't heat up as quickly.

Okey dokey...and that profile is accurate, no doubt...but even the pencil barrel Patrol Carbine could do MOA, but likely not for as many shots. Beautiful gun, excellent find, those things don't grow on trees south of the border.

I have a couple of the AR6520 rifles with the pencil barrels and love them for their light weight. They're marked AR-15 A2 Gov't Carbine.

I had two of the later ones, the A4 flattop version, 6720, called initially the AR15-A4 Lightweight Patrol Rifle, then later remarked to Lightweight LE Carbine....I would have preferred the 6520, but the 6720 was as close as I could come 8yrs ago to the weight of my old issue M16 and M16A1 before we went to the much heavier A2 and M4 and even heavier M4A1 (the latter two after my time, thank goodness). But, it wasn't too bad with the 14.5" M4 upper on it...great handy little rifles with the old M16/M16A1 profile barrels.

I might have one of those.
The A3 tactical might be the most accurate carbine.
Jus’ sayin’…..

Took it apart today for a cleaning and inspection. Even the extractor has the Diemaco/Devtek mark on it...
