Partisan Disruptor FRT + MPI BCG + Armaspec SMB H2 — Complete AR-15 FRT Upgrade Kit

The Premier Complete AR-15 FRT Upgrade Kit

Every forced reset trigger build on an AR-15 requires three things done right: the trigger, the BCG, and the buffer. Get any one of them wrong and your forced reset trigger won't run reliably — regardless of how good the trigger itself is. This bundle eliminates that problem entirely.

The Partisan Disruptor FRT, the MPI Nickel Boron M16-cut BCG, and the Armaspec Sound Mitigation Buffer Gen3 H2 — all three components, all 100% USA made, engineered to work together as a complete system. The premier forced reset trigger upgrade kit for any AR-15 platform, at the best combined value available.

What's In The Bundle

Bundle Specifications

The Partisan Disruptor FRT

The Partisan Disruptor is The Triggered Company's patented drop-in forced reset trigger for AR-15 mil-spec platforms. It installs without modification to your lower receiver and delivers the rapid, controlled cycling that forced reset triggers are known for. 3.75–4.1 lb pull weight. Compatible with 5.56, 300 BLK, and 9mm DI platforms.

The Disruptor is the most proven forced reset trigger in the lineup — in stock, battle tested, and the starting point for any serious AR-15 FRT build. This bundle pairs it with the two components it requires to run correctly from round one.

The MPI Nickel Boron BCG — M16 Cut

A forced reset trigger requires an M16-profile BCG — no exceptions. The M16 carrier tail provides the extended geometry that engages the Disruptor's reset lobe on every cycling stroke. A standard semi-auto carrier profile will not provide consistent reset regardless of buffer weight or ammo selection.

The MPI Nickel Boron BCG is the correct M16-cut carrier built to MIL-SPEC standards throughout — Carpenter 158 bolt, 9310 carrier, magnetic particle inspected, hard chrome firing pin, MIL-SPEC gas rings and O-ring. The nickel boron finish runs cleaner, runs harder, and cleans faster than standard phosphate — an advantage that compounds on every forced reset trigger build where the BCG cycles at higher rates.

The Armaspec SMB Gen3 H2 — Silent Captured Buffer

The Armaspec Sound Mitigation Buffer Gen3 H2 meets the H2 minimum threshold (4.7 oz equivalent) required for reliable forced reset trigger function. Unlike a standard heavy buffer, the SMB Gen3 is a captured system — the buffer, spring, and polymer guide rod drop in as a single unit. The spring rides on the guide rod rather than against the buffer tube wall, eliminating spring noise and reducing heat and friction on every cycling stroke.

Adjustable spring tension. Lifetime warranty. 100% USA made. At $59.99 it is the best value heavy buffer available for any forced reset trigger build — and this bundle includes it alongside the trigger and BCG it was designed to complement.

Why 100% USA Made Matters

Every component in this bundle is designed, machined, and assembled in the United States. The Partisan Disruptor FRT by The Triggered Company. The MPI BCG by MPI. The Armaspec SMB by Armaspec. No offshore sourcing. No compromised materials. The premier all-American forced reset trigger upgrade kit — built by Americans for Americans who demand the best from their AR-15 platform.
