So I'm finally pulling the trigger on a DSA STG 58. There are 2 that I'm looking at and am having a little trouble deciding. First, I'm looking at a NIB carbine with the 18" barrel. However, I also have the opportunity to pick up a standard version of the STG 58 with the extreme duty scope mount that DSA offers for about $400 less than the carbine. BTW, the standard STG is used but in excellent condition. I just can't decide and I can't buy both right now. FYI, I already have an M1A, but I've always wanted an FAL.
