The market is flooded with AR15s and probably will be for awhile, I say just make up your mind on what make you want and shop around. Patience is the key
Yes, I have been seeing more and more builds being sold dirt cheap too. They are advertised like "custom ar priced to sell", "AR reduced for quick sell", "custom precision built AR, never shot, selling dirt cheap".... Etc. etc.... It's a buyers market right now... I've also seen some real nice A2 style older Hbar rifles for sale for sub $500.00 as well... I damn near snagged a couple, but alas, probably not a great idea to just buy all the ones you see just because they are a damn good deal??? I do get a kick out of all the "Custom" AR's I've been seeing for cheap though. I guess that's better wording than I built this thing from a cheap azzed mod1 sales or PSA kit in momma's basement....
