I just picked up a Match H-bar, Colt made in 1990 that has a Mag fence, large front pivot
hole and   NO BLOCK. Is this a "white lable"?
It also has no bayo lug.

Thanks for any info!!

Hi Jack,

Yes, you are right that this Colt AR Model R6601 Sporter Match H-BAR white lable. The AR was made at Colt's beginning period where they began to make AR politically correct guns around 1989 - 1990. The AR does commend a greater value then let say a R6601 that is blocked but it’s not like a R6600, which is not block and has a Bayo lug. It’s almost a trade off. Estimated value in today’s soft market would bring between 1,300 - 1,600 clams. Please keep in mind this is my estimate.
Hope this helps ya, good to see around these parts again. You’re a good man to do business with; I have been enjoying our last business transaction by drooling all over it.

Thanks, Kirk.

Sounds like a early 1990 blue label to me.  Still have a new in the box, R-6551, with these features, purchased in 1990. Here's the
label.
