Best AEG on the market

Absolutely the best AEG I've shot so far. Michael answered all the questions I had prior to purchase and made the entire process easy. The replica shoots cleaner and smoother than anything else I've shot. I currently own an Umbrella Armory OCAW as well and I love it, but I can say confidently that the Paragon build shoots better. Paragon Armory is the new S tier that has set the standard for all other custom / high end builds to follow. Buy with absolute confidence because you will not be disappointed by the company, the people, or the product.

Absolutely overwhelmed by your positive review! Thank you so much for trusting us and giving us your business. We are glad you're enjoying your Paragon Spec AEG. Happy shooting!
