i'm not big on the idea of 30 rd magazines. my experience with them in the army was negative, and it seems to me that 20 rds is not only an ideal number for precise single shot firing, but that full 30 rd magazines present too many feeding problems. i know that many of the after-market 30 rd mags for mini 14s have bad reputations, but what about the 20 rd magazines? are most reliable, and are there any companies to avoid? i saw some 20 rd mags online for cheap. they are manufactured by a company called 'western'. anything i should know about this company?
