I'm not looking for flat tops. I'm looking for an old school A1 sporter 16" barrel carbine upper with carrying handle less the brass bump and sight adjustment wheel of the A2 upper.
You can get parts at the 1500. I have a 20" AR totally A1, thin barrel, three prong flash enhancer, even no forward assist. In fact it has all M16 internals except for the autosear.
