Great experience with op - Aero Precision M4E1 Threaded 14.5in 5.56 Mid-Length w/ ATLAS S-ONE Handguard Complete Upper Receiver with Flash Hider

I initially ordered the 14.5 barrel, and opted to exchange it for a 16 barrel when I opted to not pin/weld, SBR, or brace it up but wanted to go straight rifle with no questions about it. And going though OP during the exchange process was really easy, the customer service was stellar. And they used a promo code I originally used, but for the new item. AND they allowed me to used an additional 10% promo that came out the day of the exchange(payment). It brought the price to the 14.5 which was awesome of them. I also grabbed an aero BSG, and Warhammer charger handle and everything arrived in great condition, parts all there.
