Geissele super 42 - Geissele Super 42 Braided Wire Buffer Spring And Buffer Combo, H1 - Best Seller!

So far so good, roughly 1000 rounds with the super 42. Twang is all but gone, gun runs smooth, no malfunctions to report, although 1000 round is a small sample size. Spring and buffer are of excellent build quality, typical of geissele products. very satisfied with purchase.
