To borrow a phrase from Lawrence of Arabia, "Big things have small beginnings," and there can be few things as wonderful for a great AR build than starting with high-quality receivers. 

With that, it should surprise no one that Guns.com, the best place to buy (and sell) guns online, is now stocking AR parts, starting with a broad selection of uppers and lowers. Ranging from Aero Precision to Zev Technologies with dozens of brands in between, such as SilencerCo, Black Rain Ordinance, and Spikes Tactical, odds are there is something to cover any interest. 
 

Aero lowers
You can't go wrong with an Aero receiver for your next build.
Silencerco lower
The SilencerCo SCO-15 lower receiver is precision machined, ultra-light, and type III hard-coat anodized.
Sharps Brothers lowers
For something a little more on the wild side, you may want to check out Sharps Brothers. 


Uppers ship directly to your home or business, while lowers will go to your local FFL for pickup. Be sure to check back often as we are constantly updating our inventory.

Remember, while promises from politicians often go bad, AR receivers are much like the Constitution – they never expire – so there is no harm in having extras.
