Absolutely Fantastic Replica of the Vietnam M16A1. For most all display purposes this is a wonderful, true weight, true size , full metal receiver replica. For all those who complain that it doesn't have more moving functional parts- the only thing I can say is, those additions will only increase the price. I say keep the price reasonable, and for those that want more, spend another $350 for all those added features, but don't complain about a replica in metal, that's a super great piece that retails for under $200 I am well pleased with it. And furthermore, I can't say enough about REPLICA WEAPONRY CO., First Rate. FAST SHIPPING. A+A+A+A+A+ I could not be more pleased with this transaction. Final word: I want this for my VN display, so I took a very fine steel wool with light oil and went over the high points and edges, and man, it's spot on. Thank you Replica Weaponry!!
