    If you are looking for an AR at a price that isn't going to hurt your wallet. This is the one. I have put countless rounds through mine since I got it from WBT 7 months ago. Not a single issue. This guy is fun to shoot. You will not regret buying this.

    DB-15

    Posted by Rocky on Jul 19th 2024

    Bought a DB-15 with Magpul furnitures with it during Memorial Day Sale Promo with discounted pricing. Gun was well worth the purchase price, have tested and fired it, performed as expected and more. Have already upgraded the furnitures and it looks great, Totally satisfied with its performance and looks, great value, great price.

    Under promised..over delivered.

    Posted by Shawn on Jul 16th 2024

    This was my first time ordering online and shipping to my local FFL for transfer. WBT made it incredibly easy from start to finish getting it done. Their ship time, to me at least, was crazy fast compared to what I was expecting. As far as the Diamond Back DB15. Great starting platform. Super easy to make upgrades. Had to put the kingpin on it of course but there are options now for rear pins. Overall great.

    First AR

    Posted by Mark Estrella on Aug 20th 2023

    Great value for a first AR from Wilde Built for CA. Wilde Built called me just before shipping it off to confirm and offer their availability once I do receive the AR. I replaced the takedown pin with the Maglock King Pin and is a tactical beauty. The Magpul furniture makes is easy for accessories of your choosing, e.g. light mount, laser, scope, dot. I've already taken tactical courses with this DB15 and am looking forward to using it to take my first wild pig!
