Who can Design and Assemble a Custom Firearm to Meet My Wants and Needs?

Black Diamond Armory is a fully Federal Firearms Licensed, Full Service Firearm Dealer that specializes in custom AR-15’s.

The look is as important as the function for today's shooter. Black Diamond Armory will lend a hand from the design process all the way to final assembly to create the one of a kind AR that stands out at the range. The days of cookie cutter AR15 rifles are behind us, now is the time to enjoy the performance and add 'The Look' to a tried and true rifle.

"I bought the gun oil from you today and tried it on several firearms and I love it so far! It applies like a dream and feels and looks awesome! I am totally sold, and I have used many oils over the years! To say this is the best so far is an understatement.  When I have some extra cash, I will buy a dozen or so and give them to all my friends. Thanks for totally rocking this!"

 

Don't forget, we now stock and sell a wide variety of ammo!
