Complete Upper Units

​Sota Arms complete upper units are COMPLETE with bolt carrier group and charge handle.  Don’t be fooled by others that claim the upper is complete when it doesn’t have the charge handle nor the bolt carrier group.   We have plenty of options from various barrel lengths, handguard lengths and calibers, to name a few.  

​Sota Arms always test fires every complete upper as it’s final quality check to verify cycling.    

If you are looking for a complete upper unit, SOTA Arms has you covered. We carry AR 15 uppers in a variety of calibers like 6.5 Grendel, 5.56, .300 Blackout, .224 Valkyrie, and more! We also offer .308 complete AR 10 uppers. Don't be fooled. Other companies may offer "complete upper receivers" that don't actually come with the charging handle and bolt carrier group. Our complete upper units come with the upper receiver, M-Lok or Keymod  handguard, charging handle, bolt carrier group, gas block, muzzle device, and rifle barrel. Each caliber has tons of options to choose from with varying barrel lengths, twist rates, hand guard lengths, and gas block styles.
​
Our complete upper units are crafted using  416R stainless steel or 4150 Chromoly barrels and given a black R3 Anodized finish on the upper receiver.  These uppers are designed to drop onto a Mil-Spec lower receiver. We manufacture all of our AR-10 and AR-15 parts and components in-house, right here in the USA. Your next AR-15 or AR-10 build starts here. Trust us to set you up for success and buy American with PRIDE!
