Each ASC308 Ambidextrous AR10 Billet Lower Receivers feature dual controls for the bolt catch release and magazine release.  We provide all the extra parts necessary for assembly.  Combine them with an ambidextrous safety and trigger to complete the lower.

  • NLX ASC308 Billet Ambidextrous Lower Receiver

All of our ASC308 receivers are DPMS Gen1 pattern, the uppers are low profile (.150 tang).  Please feel free to contact us with any questions regarding compatibility.  Our Lowers Use DPMS Pattern Magazines.


*NOTE:  We now offer two options for your ASC308 AR10 billet upper: Right hand Gen 2 or left hand upper.  Both uppers are backwards compatible with the previous lowers. Due to the dual bolt catch design, neither of the uppers use a dust cover.*
