This guide details how to troubleshoot and tune an AR-15 equipped with a Forced Reset Trigger (FRT) that experiences a 'one click' failure. Expert instructor Brody from Juicey Media explains the importance of BCG velocity and dwell time, demonstrating how buffer weights, springs, and buffer systems like the VLTOR A5 can resolve cycling issues, especially when using suppressors. The video emphasizes that each rifle requires individual tuning to find its optimal 'sweet spot' for reliable FRT operation.

Quick Summary

Troubleshooting an AR-15 with a Forced Reset Trigger (FRT) that fails to reset often involves tuning the buffer system. Insufficient bolt carrier group (BCG) velocity or improper timing, exacerbated by suppressors, can cause 'one click' failures. Adjusting buffer weights, springs, or using systems like the VLTOR A5 can resolve these issues by ensuring reliable cycling.

Frequently Asked Questions

What causes an AR-15 with an FRT to fail with a 'dead trigger' or light primer strike?

This common issue, often called the 'one click' problem, typically stems from insufficient bolt carrier group (BCG) velocity or timing. The rifle fires once but doesn't cycle correctly to reset the trigger, often due to an incorrect buffer weight, spring, or gas system tuning, especially when using a suppressor.

How can I tune my AR-15 for reliable FRT function, especially when suppressed?

Tuning involves adjusting the buffer system. Start with unsuppressed testing, progressively increasing buffer weight. When suppressed, increased backpressure requires further tuning, potentially with heavier buffers, different springs, or systems like the VLTOR A5 to ensure proper BCG velocity and cycling.

Is the VLTOR A5 buffer system effective for FRT tuning?

Yes, the VLTOR A5 system, which uses a longer buffer tube, specific buffer, and rifle-length spring, is highlighted as an effective solution for improving controllable and reliable suppressed fire with FRTs. The A5H3 buffer is often recommended as a starting point.

What is the risk of over-buffering when using suppressors with an FRT?

Over-buffering, especially with low-backpressure suppressors, can lead to short-stroking. This means the BCG doesn't travel far enough back to fully cycle the action and reset the trigger, causing malfunctions and preventing reliable operation of the FRT.
