About the brands
- Aero makes forged AR receivers, mainly the M4E1 line, with a billet look that still takes standard mil-spec parts. More on Aero Precision
- TacFire is a dealer only wholesaler, so you'll find its stripped uppers, lower parts kits and AR kits at online retailers, not on its own site. More on TacFire
