KAK Industry AR-15 LPK Basic Ambidextrous Build Kit - AR15-LP-KT-03 - 811163035828

Product Description

Assembling or refurbishing a custom AR-15 lower receiver requires a complete set of precision-machined lower receiver components that ensure smooth mechanical lockup, crisp trigger engagement, and bilateral control indexing. Standard lower parts kits often include low-grade cast components or single-sided safety selectors that create control friction for left-handed shooters or dynamic off-shoulder barricade staging. The KAK Industry Basic Ambidextrous AR-15 Lower Parts Kit (AR15-LP-KT-03) resolves control access and manufacturing tolerance issues by combining a complete Mil-Spec lower hardware kit with a heavy-duty ambidextrous safety selector.

Precision-manufactured to strict Mil-Spec engineering dimensions, this basic lower receiver build kit includes all critical internal pins, springs, detents, catch hardware, and an ergonomic pistol grip. The included dual-lever ambidextrous safety selector provides smooth, positive detent engagement from both sides of the receiver, allowing seamless fire control manipulation for left-handed operators or off-shoulder tactical transitions. Treated with corrosion-resistant dark finishes across all high-wear springs and pins, every component is engineered to withstand aggressive recoil schedules and harsh environmental exposure.

Ideal for custom rifle builds, bench rest staging, or complete lower overhaul projects, the KAK Industry AR15-LP-KT-03 kit delivers genuine Mil-Spec fitment and ambidextrous versatility across all standard AR-15 lower receivers.

*Armorer Bench Notes & Real-World Staging Guidance:

Fitment & Platform Compatibility Matrix: Designed for standard Mil-Spec AR-15 forged and billet lower receivers (0.154" trigger/hammer pin holes, 0.250" takedown/pivot pin holes). Note: Contains all lower hardware, pistol grip, and fire control group components required to finish a stripped lower receiver.

Assembly Sequence:

  1. Safety check the workspace and inspect stripped lower receiver pin channels.
  2. Install the magazine catch, mag release button, and spring; assemble the bolt catch using a roll pin punch with masking tape to protect receiver finish.
  3. Install the front pivot pin and detent using a pivot pin installation tool to prevent detent spring loss.
  4. Install the trigger group, disconnector, hammer, and J-pin springs using 0.154" anti-walk or standard pins; install the ambidextrous safety selector levers and detent.
  5. Install the rear takedown pin, buffer retainer assembly, A2 pistol grip (with selector detent spring), and buffer receiver extension assembly according to standard armorer torque specs.
