Design and Build Your Custom AR 15 on a Budget

Design and Build Your Custom AR 15 on a Budget

The Easiest Way to Build Your Own AR 15 Rifle or Pistol

If you go to any off-the-shelf gun centers and buy an entry-level mil-spec AR15, you will likely end up with an A2 System. They often come standard with an A2 front sight and a plastic clam-shell handguard with no attachment points. It also likely has a standard A2 flash hider. While it is still quite functional, it looks old-fashioned and honestly dull.

Why would you ever buy a standard AR 15 if you are not bored? Especially when you can easily buy a stripped lower receiver and assemble it yourself. When you build your AR 15, you can have it look exactly like you want. Not to mention the satisfaction you get from using your hands to assemble your rifle. We suggest you design and build your AR rifle or pistol from scratch. That way, you own a gun that fits your style from the start.

Where to Start; Do you think you should buy parts or kits?

Oh! So, it would be best if you were more confident in correctly picking out and assembling all the various parts and components required to create a working AR rifle. No worries, we have every type of AR builder covered at Black Rifle Depot.

We offer a vast selection of live-online inventory of individual parts for the designer who knows exactly the amount they want and complete* rifle and pistol build kits for the builder who prefers to know what it will look like before starting.

Rifle Build KitsTHESE KITS MAY NOT BE COMPLIANT WITH YOUR STATE OR LOCAL LAWS. REFER TO YOUR STATE OR LOCAL LAWS TO SEE IF YOU CAN OWN A STANDARD UN-MODIFIED AR RIFLE/PISTOL. AS THESE KITS ARE STANDARD AND NOT MODIFIED IN ANY WAY TO BE COMPLIANT WITH ANY STATE LAWS.

*Please note… Our Build Kits do not come with a lower receiver. You must purchase a lower receiver from a licensed FFL dealer and submit to the proper background checks to take possession of the lower receiver.

**Black Rifle Depot makes no guarantees or assumptions about your ability to purchase or own a registered AR 15 lower.

If you already own an AR that is or is not an A2-style rifle, we have plenty of options, including our complete lower-build kits and upper assemblies so that you can customize and upgrade your current weapon.
