Yesterday at the PHX gun show I purchased a new unfired Colt Sporter lightweight in 9mm ser #
NL 002xxx. I have owned alot of AR's in .223 but never a 9mm. Can anyone offer any information, reviews, opinions, or suggestions on these rifles. Is the sighting in different and such. I got the 1 Colt 32 rounder that came with the rifle and have a guy getting me 3 more. They are a little expensive but no more than most Glock hicaps are going for now. Any constructive input would be appreciated....
