It really isn’t rocket science to build your own gun.

I mean, it’s ballistics science and engineering. So it’s close, but it really isn’t as difficult as you might think to put together your own near-perfect Glock or indeed a DIY AR-15.

You can build an AR-15 for less than $700 that should be, or could be, a match for much more expensive off-the-shelf weapons.

Don’t Build a Bad AR-15

Of course, you always have the chance to get it badly wrong.

Mismatched parts, poor attention to detail and even not knowing when to stop can give you a complete mess of a gun that you spent too much money on.

But get it right, or close to right, and you can spend months switching out parts on your home-made gun, improving and refining, to create as near as damnit the perfect AR-15.

You can even put one together and they’ll build it, but it’s way cooler to handle the nuts and bolts yourself.

Having said that, for your first build you might want to keep it simple. You can buy complete or stripped receivers and a complete kit will save you time.

Palmetto State Armory has a great deal on an AR15 upper receiver, complete with a Nitride-finished barrel, for just $350 if you go for the BLEM parts. You can upgrade all of these parts over the course of time, but this is a great price point to get you started and it should save you money on building the gun piece by piece.

Watch the Sales For AR-15 Parts

Always keep an eye on the sales on Brownells too. Right now, you can get a real nice Geissele two-stage trigger kit for 30% off retail. You could also buy a complete Aero Precision kit that costs less than $500 with a full Cerakote camo finish.

When you come to order your gun, you might find a Noveske lower receiver.  You might find a killer optic or even a Blackout Rifle conversion kit with a full upper receiver and barrel.

You can switch between the two if you get a second upper receiver, dedicated to the Blackout rifle set-up. So there are all kinds of variables that could take your gun from $750 for a perfectly  good AR-15 through to thousands for the best of the best.

Shop Around For the Best Deals

Make sure you shop around, too. Rainier Arms has some amazing deals and you could  mix and match the perfect rifle between these two suppliers and get it all for an insane price. That’s the dream when you build an AR-15.

Rainier Arms has a Gen 3 upper and lower receiver from Noveske for $550, which would be the heartbeat of a world-beating AR15.
Just always keep an eye on your overall cost and then re-evaluate if you want to build or just buy.

So, should you build an AR-15?

It can be fun. It will also give you a fuller understanding of your AR-15 and it will deepen your bond with it as you keep improving it with new parts.

When you’re feeling full of cash, check what’s on sale at Brownells and slowly upgrade your AR-15 to world class competition spec.

Titanium everything, a Noveske barrel and other leading accoutrements could turn yours into a $2000 AR15. But then you’ll have the ultimate Modern Sporting Rifle and you will have built it yourself.

That kind of rocks to know when you get in to position and take aim.
