DPMS A-15 5.56 AR-15 Rifle with Barska Red Dot Optic Red/Green

I purchased a used bone stock DPMS Panther model A-15 with a cheap barska red dot scope which needed a heavy cleaning when I received it which was fine as it’s a good idea to disassemble and inspect anyway but this rifle brand new runs around $699. If the rifle had at least a better hand guard I might feel different but suffice to say I have buyers remorse on this purchase. Next time I’ll be more patient.
