The Easiest Way to

BUILD YOUR OWN AR15

Why Buy Stock When You Can Build Your Own?

1. Choose To Build A Rifle or Pistol

2. Select Your Handguard Length

7-inch (pistol), 13-inch, 15-inch

3. Pick Your Muzzle Device

Muzzle Brake, Flash Can, Flash Hider

4. Get Your Add-Ons

Tool Kit, Range Bag, Iron Sights

That entry-level mil-spec AR15 you can buy off the shelf? Convenient, but common. It likely has an A2 System with an A2 front sight and a set of plastic clamshell handguards with no attachment points. It likely has an A2 flash hider. It is clunky and "old" looking. It's your Dad's AR15 rifle.

So the question is – why buy standard? Build your own AR15 and get what you want, assemble it from scratch, and own a gun that fits your style from the start.

Here's the problem. Sourcing parts and making sure they meet your standards is both time-consuming and expensive. You'll be swimming in options, unsure you can trust foreign suppliers, waiting on shipments, and, inevitably, spending too many hours or dollars to justify the build.

Good thing you're here. At BYOAR, we believe you don't have to be an expert to build your own AR. We also believe you can get what you want without lowering your expectations or raising your budget.
