For under $100 you can get a legit Russian M23 Pioneer chest rig. I have one - it's bombproof. Holds 8 mags and all the other crap you may need. Fantastic stitching, super-heavy-duty fabric (Kodra 1000, russkie equivalent to 1000D Cordura). They are a bit hard to find now, but a great peice of kit.
