What is included in the H3 FRT bundle?

This bundle includes three components: the Partisan Disruptor Forced Reset Trigger ($299.99), the MPI Nickel Boron AR-15 BCG with M16 cut ($159.99), and the Armaspec Sound Mitigation Buffer Gen3 H3 silent captured buffer ($59.99). Combined retail is $519.97 — bundle price is $469, saving you $50.97.

Why is the H3 bundle recommended for suppressed builds?

Suppressed AR-15s run more gas pressure through the system than unsuppressed rifles, which causes the BCG to cycle faster. A faster-cycling BCG on a forced reset trigger build means the bolt returns to battery before the reset mechanism can engage — causing short strokes and reset failures. The H3 buffer at 5.6 oz equivalent weight provides more mass to slow the bolt return and compensate for the additional gas pressure, giving the forced reset trigger enough time to engage reliably on every cycle.

What is the difference between the H2 and H3 FRT bundle?

Both bundles include the same Partisan Disruptor FRT and MPI Nickel Boron BCG. The H2 bundle ($459) uses the Armaspec SMB Gen3 H2 at 4.7 oz equivalent — the minimum threshold for most standard carbine FRT builds. The H3 bundle ($469) uses the SMB Gen3 H3 at 5.6 oz equivalent — recommended for suppressed builds, short-gas systems under 16 inches, and any build where you want maximum cycle control margin. If you're running a can or a shorter barrel, choose H3.

Why does a forced reset trigger require an M16 BCG?

The Partisan Disruptor forced reset trigger requires an M16-profile carrier for reliable reset function. The M16 carrier tail engages the Disruptor's reset lobe on the forward cycling stroke. A standard semi-auto profile carrier does not have this geometry and will not provide consistent reset.

Is this bundle 100% USA made?

Yes. All three components are 100% USA made — the Partisan Disruptor FRT by The Triggered Company, the MPI Nickel Boron BCG by MPI, and the Armaspec SMB Gen3 H3 by Armaspec. The premier all-American forced reset trigger upgrade kit.

Can I adjust the spring tension on the Armaspec H3 buffer?

Yes. The Armaspec SMB Gen3 H3 features an adjustable main spring that can be trimmed at 0.25 lbs per coil to reduce tension, up to a maximum of 12 coils. This lets you fine-tune the buffer system to your specific gas system, barrel length, suppressor, and ammo without swapping components.

Is the Armaspec SMB Gen3 H3 compatible with Super Safety builds?

Yes. The Armaspec SMB Gen3 H3 and MPI BCG in this bundle are both compatible with Super Safety builds. The Partisan Disruptor FRT is a forced reset trigger — if you are building specifically around a Super Safety, the BCG and buffer in this bundle are correct but you would substitute the appropriate Super Safety for the Disruptor trigger.

The Premier AR-15 FRT Kit — Built for Suppressed & Short-Gas Builds

Every forced reset trigger build on an AR-15 requires three things done right: the trigger, the BCG, and the buffer. The H3 version of this bundle is engineered specifically for shooters running suppressors, short-gas systems, or sub-16" barrels — where standard buffer weight isn't enough and you need maximum cycle control margin from the start.

The Partisan Disruptor FRT, the MPI Nickel Boron M16-cut BCG, and the Armaspec Sound Mitigation Buffer Gen3 H3 — all three components, all 100% USA made, all shipped together. The premier all-American forced reset trigger upgrade kit for the shooter who demands the best.

Why the H3 for suppressed and short-gas builds? Suppressors increase gas pressure through your AR-15 system, causing the BCG to cycle faster than on an unsuppressed rifle. Short-gas systems under 16" have the same effect. On a forced reset trigger, a faster-cycling BCG means the bolt returns to battery before the reset lobe can engage — causing reset failures. The H3 at 5.6 oz equivalent slows the bolt return enough to compensate, giving your forced reset trigger the timing margin it needs to run reliably on every cycle.

H2 Bundle vs H3 Bundle — Which Is Right for You?

	H2 Bundle — $459	H3 Bundle — $469 (This Product)
Buffer Weight	4.7 oz equiv. (H2)	5.6 oz equiv. (H3)
Standard Carbine 16"	Recommended	Works — more margin
Suppressed Builds	Marginal	Recommended
Short Gas / Sub-16"	May need tuning	Recommended
High Round Count Builds	Good	Better long-term margin
Price	$459	$469

Not sure which to choose? Go H3. At only $10 more than the H2 bundle, the additional buffer weight gives you more margin for reliable forced reset trigger function — especially as component wear accumulates over higher round counts. The H3 is the safer long-term choice for any serious FRT build.

The Partisan Disruptor FRT

The Partisan Disruptor is The Triggered Company's patented drop-in forced reset trigger for AR-15 mil-spec platforms. Drop-in cassette — no modification to your lower. 3.75–4.1 lb pull. Compatible with 5.56, 300 BLK, and 9mm DI. The most proven forced reset trigger in the lineup. This bundle pairs it with the M16 BCG it requires and the H3 buffer that keeps it running reliably under the increased gas pressure of suppressed and short-gas configurations.

The MPI Nickel Boron BCG — M16 Cut

No forced reset trigger will run reliably without an M16-profile BCG. The MPI Nickel Boron BCG provides the correct M16 carrier geometry that the Disruptor's reset lobe requires — plus MIL-SPEC construction throughout. Carpenter 158 bolt. 9310 carrier. Magnetic particle inspected. Nickel boron finish that runs cleaner and cleans faster than phosphate. On a suppressed build cycling at higher rates, a BCG that resists fouling buildup is not a luxury — it is a necessity.

The Armaspec SMB Gen3 H3 — Silent Captured Buffer

The Armaspec Sound Mitigation Buffer Gen3 H3 at 5.6 oz equivalent weight is the recommended buffer for suppressed forced reset trigger builds and any AR-15 running a short-gas system under 16 inches. The captured polymer guide rod keeps the spring off the tube wall — eliminating the metallic spring rattle that gets dramatically louder under a suppressor — while the H3 mass compensates for the additional gas pressure that suppressors generate. Adjustable spring tension. Lifetime warranty. 100% USA made.

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. The premier all-American forced reset trigger upgrade kit — built by Americans for Americans who demand the absolute best from their AR-15 platform.
