Lower Parts Kits
The building base for your lower receiver builds.
Do not worry about any of these parts - if they fail, we'll replace them. If you fail them, however, we'll help you out with a replacement (yes, we know those pesky detent pins fly across the shop sometimes).
Options:
- Full Assembly Special: Mil-spec+ parts including trigger guard (billet aluminum enhanced guard), melonite treated parts, standard safety and bolt release, and A2 style grip. Does not include a trigger. Ideal for building up forged (mil-spec) lower receivers.
- Builder Special: Mil-spec+ parts including springs, detents pretreated with Breakthrough Oil, melonite treated selector, bolt release. Does not include a grip, trigger guard, or trigger assembly. Ideal for building up a billet lower receiver, or Aero/Ballistic Advantage enhanced lowers.
