Those are about the only requirements, Flat Top, 16" Chrome Lined with flash hider, 6 Position Stock, BUIS, I'd like M4 feed ramps. Chambered in 5.56 is a must. Looking to pay no more than $650. A railed handguard is a plus. Pre-ban only, please.
This whole thread is a mess, people are insulting me when I reject their offer, just because I'm not paying my entire budget on an upper and stock. I did say complete rifle. If you don't have a COMPLETE RIFLE for the price listed, fitting my requirements, don't bother, please. It's a waste of my time and yours.
