On ar15builder.com, Brownells has combined almost 600 images of external AR-15 parts and accessories so you can mix and match parts to see exactly what your own, custom AR can look like with your selected parts installed, and you don't have to lay out any cash right now.

If you want a flattop with an ACOG, a fixed stock, and standard handguards, select the component family from drop-down menus, and photos of the available options will display across the top of the screen. Click on, or drag and drop, the one you want and ar15builder.com will put it on your gun. All color variations of the products listed are shown too. If you want to see if you like a black receiver with a tan handguard and O.D. green buttstock, ar15builder.com will show you. If you want to change any component, and see what the price difference will be, just go back to the menu and click on, or drag, the new choice. The prices change in real time. When you have the accessories you want, you can click on "Order" and your parts will be on the way to your door. Or, save the "build" for later, and start on a new one. You can "own" a virtual, tactical carbine, a long range rifle, and a varmint gun, all before you put down your hard earned money.

"I'm absolutely amazed by what our folks have put together with ar15builder.com," said company CEO Frank Brownell, "this makes it easy to turn your vision into a reality."

With billions of combinations, it's easy to create the unique look you want, in the price range that suits your budget. To make it really easy, you can select pre-made builds from the drop down menu and buy everything there, or change what you don't like. Kits of internal parts are also shown, allowing anyone to assemble a complete gun and see the price.
