Andro Corp Industries (ACI) is known for offering good quality, complete AR-15 upper receiver groups at a very budget friendly price. Many of their upper regularly cost less than $400. Don’t let the prices fool you into think these aren’t quality uppers. They use barrels from Ballistic Advantage and come with various hand guard options in that price range including free float rails.
In addition to their more budget friendly line, ACI has been introducing uppers that have more premium features but are still reasonably priced. Many of these more premium uppers include rails from SLR Rifleworks who is now providing OEM support for ACI. That means you will see more SLR Rifleworks hand guards with ACI branding on uppers going forward.
The availability of reasonably priced uppers with Ballistic Advantage barrels and SLR Rifleworks hand guards is a win for AR-15 shooters. Check out the full line of uppers in various calibers at Andro Corp Industries.
