I recently purchased 5 vintage AR15 barreled uppers at the shop. The barrels are 20".
They have smooth triangle handguards with heat shield. The rear sight has windage adjustment only and there's no forward assist. Some of the barrel are marked CMP which is a Colt marking and other barrels have no markings. They all have a standard A1 type flash hider rather than a 3 prong/duckbill. What do I have and what are they worth in good condition...??? td

Nothing between the FSB pins? No numbers out by the muzzle?
|
Good clear photos of each upper, taken from the ejection port side, with the dust cover closed...will help us ID the uppers.
Also include details of every barrel marking on all five barrels. Anything near the muzzle (C-MP-C is different than C-MP-B which is different that C-MP-Chrome Bore)? Anything under the front sight? Anything under the handguards? You've come to the right place. Give us enough details, and we'll answer your questions! |

Then you can post asking "how much is it worth" and wait for the offers to flood your IM and email address.

Great score and welcome to retroland if you haven't dropped in previously. Read the Colts rifle guide at top of page for barrel markings. 604 barrels will have the same markings as 603 and earlier in guide. It will show you the different markings on barrels to help you identify. They are all 604 if front pin hole is rebated on left side and standard pin size. Need to figure out if square forge or round forge. Guide will show differences from XM16E1 to M16A-1 for square to round forge. Same time frame for 604 basically. Close up pics of right side sight area, port door and forward to slip ring and right side front lug for dating receivers.
The 604's are in high demand right now so I don't think I'd consider any offers under $500 each as barrels and upper receivers alone are bringing more than that sold individually. I'm sure you've already had a few low ballers. Just a little heads up. If square forge they will bring more also. I'm a 604 nut so if you want to know what you have and true value hit me up via e-mail. |
