My first AR and I still love it
I bought my Bushy 14.5AK Shorty around 89 and still have the original mags I shoot it with.
After I bought that one I was hooked or AR's.
I still have the 2 factory 20-round mags that came with it and a buck of "Adventure Line 20rnd mil-surp mags I use in it and my other AR's.
I prefer the 20 round mags so when I shoot off a bench with the short Harris Bipod it clears the table.
I use 30's in contentions where I'm shooting off hand but I mostly use the 20's.
All of my mags are in good shape but my Bushmaster mags are better quality than my Colts even.
Best quality AR mag you can buy.
