Not only was Amped Airsoft the only US airsoft retailer that had this item instock, they were also the lowest price. Fast shippipng, well packaged and delivered promptly and undamaged. What more can you ask for from a retailer? I will tell you about that also. I reache dout to them to discuss another gun project. I want to convert an aeg .308 to hpa with a mechanical closed bolt for DMR. They offered sugestions on gun base, barrel and barrel length, which engines would be best suited, etc. This is going beyond what I would normally expect from a company regarding customer service. This is why they have gained my repeat business.
