The three images in this post are scans from documents in a 1999 Colt press kit that I have. The ‘Compensated Match Target’ rifle shown is the only Colt AR design with an advertising sheet in the press kit. The first two images are the front/back of that advertising sheet.
For historical price reference, the third image is a scan of the AR section of the Colt price guide for 1999. As you can see prices from 1999 to now have remained almost unchanged.
There were two models in the ‘Compensated Match Target’ product line. They were the MT6601C Match Target HBAR (1/7 rifling) and the MT6700C Match Target Competition HBAR (1/9 rifling).
