I haven't picked up a AR15 since Vietnam So I was in the gun shop and they were selling complete DPMS lowers.
Then I found a S&W upper with a Colt carrying handle and a Yankee Hill flip up front sight.
When I put them together I couldn't hit the target at 50yards. I have no idea what it was sighted in for.
I was thinking of either, taking off the Colt handle and putting on a Yankee Hill rear sight or putting on my Super Sniper 10X40 scope with Warne rings.
Or should I just buy a rear flip up sight.
I'm never going to shoot this past 100yards.
Any suggestions?
