Buy the Gun and the Device Together — We Fit It Free

Buy a firearm or a lower from us in the same order as a Forced Reset Device — a trigger or a selector, depending on the system — and our gunsmith installs it free. Build your own, or pick from our favorites. Want it proven before it ships? Add test fire and tuning for $100.

  • Free Fitting and install Free when the gun or lower and the device are bought here together. Installing a device you bring us is $100.
  • $100 Test fire and tuning Optional. We run it, tune it and tell you what it did. Does not include a replacement buffer, if one is needed to make it run.
Option 1 · Build Your Own
Start From Scratch

Pick the firearm or lower, pick the Forced Reset Device, and we fit them together before it ships. Live pricing as you configure.

LWRC IC-DI 5.56 · Rare Breed

The nice one. An LWRC IC-DI in 5.56 — 16.1" M-LOK, direct impingement — with a Rare Breed FRT-15L3. Rare Breed publishes no compatibility list for any specific AR-15 lower, so our gunsmith verifies the fit on the bench before it ships, and tells you if it will not.
