Me, too. I have built 4 or 5 rifles with Superior lowers.
No problems on fit and finish. No problems what so ever.
I have since found a local shop that has stripped lowers
at a better price, but if I didn't have this source, I
would be back buying Superior lowers from a not quite as
local source.
About the only kick against them is they are not well known,
so re-sale value can take a ding, if the buyer is hung up on
a "brand" name. The only time I ever had a problem was I was
trading an AR-15 for another firearm, at a local gun and loan
store. They quoted me a stupid low price, and I walked out.
Swapped a Superior Arms lower, with a NM trigger, and a CAA
stock out for a cheaply priced DPMS lower with a std fire
control group, a cheap M4 stock, and some minor finish issues,
and went back to the gun and loan store, and they quoted
me a better trade-in price than I wanted! Moral of the story
is better guts means less than the name stamped on the
lower, to some buyers.
