McCollum and Vickers reviewing a Colt 723 clone used by Vickers during his time in SFOD-D. Goes into the in-house bells and whistles they installed and modified on these carbines during Vickers' earlier time in Delta(late 80's/early-mid 90's). Lots of neat Delta gunsmithing and history here that I never knew. These rifles and their configuration by Delta were the inspiration and framework for the M4.

Really cool video. Cheers, enjoy- YZ
