HAs anyone dumped mags while using this quad rail? If so, did it get crazy hot? I bought a cheap ebay quad rail ($30) that looks good and feels solid, but when I mag dump just one mag, it gets too hot to touch. Even starts softening rail ladders. Reason I bought the damn cheap rail was because I didn't want to spend allot on a rail to just add a Magpul AFG2. Live and learn.
