A few months back I ran an article on Doug Mullen's RAMP:Rapid Access Magazine Pod. I thought I'd follow up with another video Doug made showing how the RAMP works. It's important to remember this isn't necessarily designed to replace a full load-out, and that it is built different than an ITW Fastmag (that is usually the first comparison made). I haven't personally run any RAMPs on the range, but I did finally get my hands on some at TTPOA and BORTAC/SOG, and my initial impressions are very positive.
