PSA is arguably the most important brand in democratizing AR-15 ownership. Based in South Carolina, they manufacture at scale and pass those savings directly to the consumer. Complete AR-15s under $500 with mil-spec components are routine from PSA — something almost no other brand can claim consistently.

Their Freedom and PA-15 series offer chrome-lined barrels, forged receivers, and carbine buffer systems that run reliably for most shooters. QC can be inconsistent compared to more premium brands, but PSA has made meaningful strides in recent years, and their lifetime warranty is genuinely backed.

Aero Precision occupies a sweet spot for builders: their M4E1 and ATLAS receiver sets are machined to tolerances that rival brands charging twice the price. Born from aerospace manufacturing, Aero brings a different standard of precision to forged and billet receiver sets.

Their integrated trigger guard, improved upper tension screw system on the M4E1, and consistent anodizing make Aero receivers the default recommendation for custom builders. Complete rifles from Aero are also excellent, though the real value shines when you're spec-ing your own build.

The Ruger AR-556 is the AR-15 for buyers who want a name they recognize behind their rifle. Ruger's quality control and nationwide warranty network are genuine advantages, and the AR-556 ships with a cold hammer-forged barrel — a spec you'd expect at a higher price point.

It's a no-frills, runs-reliably-and-looks-like-an-AR rifle. It won't excite gear enthusiasts, but it won't let you down either. For buyers picking up their first rifle at a local gun store, the AR-556 remains one of the safest choices in the $700 range.

Anderson is the go-to brand when you want to build your own rifle on the absolute tightest budget. Their stripped lower receivers are frequently the lowest-priced forged aluminum option on the market, and they've earned a reputation for being perfectly functional despite their economy price.

Complete Anderson rifles are competitively priced and serviceable, though they're not the choice for a duty or competition build. Where Anderson truly shines is as a starting point for a first build — buy the stripped lower, add quality components from Zaviar, Aero, or BCM, and end up with a better rifle than a budget complete gun at a similar price.
