What would be my best option for a magazine for a 338 edge that I'm having built?? I had an HS ordered b/c I could get one so cheap but they just told me that I'm at least 2 more months out on it (and I ordered it the first of Nov!!). So to heck w/them. I'm looking for other options. I kinda like the detachable mags but would consider a floor plate as well.
