how low and still function and in the realm of 1-2 MOA is mind boggling. But I learned that in the 80s playing with parts guns. The parts were sometimes way worse, but it seemed that any cheap barrel was decent, somewhat more reliable than a factory deer rifle being really accurate.
Its only gotten better I think. Especially having some junk guns back then that won serious matches. And junk guns these days that hover at MOA and don't mis step. All for pennies on the dollar as they say
