Do you know who did the conversion? Should be listed on the F-4. Can you post a pic of the conversion maker's stamping(s)?

 

Thanks,

Kent

The conversion was done by RPB Industries, Inc. But they did not stamp the firearm as far as I'm aware, I could dig it out of the safe and check again, but I fairly certain it isn't stamped. Let me know if there is anything else I can help you with.

The RPB markings may be under the grip.

Thanks, I'll take a look when I have a chance to remove grip, and then I'll post a picture of anything I find.

You can look thru the vent holes on the underside of the barrel

???  The Colt pictured in this thread is not a Colt factory AR15 Model 614.  It is clearly marked "SP1" on the mag-well, fire control markings are only "Safe" & "Fire" and the owner states it's an RPB conversion.
