The web sight looks like he is a cross-dock shipper. You order from him, and he orders from a wholesale place and ships to you.
He lists most popular guns, but does not say much about what he had in stock. I highly doubt he has inventory on hand.
The descriptions look like they are word-for-word copied from other web sites.
There are "likes" counters on the products, but I did not see any "reviews".
The above is not to say he is dishonest. I have no experience and have not heard anything about the business or the owner.
My money says no thank you.
