Sports cams have gotten smaller, lighter and better than ever in the last few years. Compared to the newest batch of go-anywhere, film-anything action cameras, last year’s snazziest models are already starting to resemble VHS camcorders. The $199 Replay XD720 is tiny, weighs almost nothing, and attaches to absolutely anything including your Picatinny rail-equipped firearms. This makes it ‘gun gear’ and means I get to review it without Farago carping about ‘mission creep’. I won’t even have to insert a gratuitous SIG/Sauer P226 photo at the end! But I probably will anyway . . .
