AR-15 FRT Sampler Pack

Got multiple rifles, or unsure which variant will perform best in your specific setup? The Kabuto FRT Sampler Pack takes the guesswork out of the equation. This bundle gives you the opportunity to test out three different material and size configurations across your builds to find the exact sweet spot for your setup—all while getting a high-value bonus item included.

What’s Included in the Sampler:

1. Full-Size Kabuto (Stainless Internals): Built for robust durability, featuring 304 stainless steel internals, a rugged tool steel pin, and our signature internally reinforced ambidextrous safety.

2. Mini Kabuto (PA12-CF Carbon Fiber Nylon Housing & Stainless Internals): A compact, high-heat engineering polymer housing paired with laser-cut stainless internals and our full-length screw-reinforced safety selector.

3. FREE Bonus — Full-Size Poly Kabuto: A lightweight all-polymer variant featuring a tool steel pin and our reinforced safety, included completely free to round out your testing suite.

Why Grab the Sampler?

• Test Across Platforms: Different lowers, buffer weights, and BCG tolerances can react uniquely to rapid reset systems. This pack lets you dial in testing across your entire collection.

• Unmatched Value: Get three distinct setups to compare fitment, weight, and feel without buying separate standalone units at full price.

• Shared Upgrades: Every unit in this sampler features your custom redesigned ambidextrous safety, internally reinforced with a full-length stainless steel screw to eliminate high-stress failure points.

Quick Compatibility & Tuning Reminder

• Platform: Designed for standard AR-15 platforms with low-shelf or M16-cut lowers and mil-spec fire control groups.

• BCG Requirement: Requires an M16 bolt carrier group.

• Buffer Weights: Because these systems run at an extremely high rate of speed, some builds may require an H1, H2, or H3 buffer to properly tune bolt speed and prevent timing jams (never use a solid rifle buffer).
