Finally the perfect FRT (Forced Reset Trigger) option for the HK MR series! Get the "auto like" experience you've been looking for from your HK MR556 or MR223 rifle, without compromising the HK factory look and feel.
Why Choose The RBT FRT-MR3™:
- Dropin trigger unit/pack/housing
- Compatibility with factory selector levers
- Includes both 90 and 45 degree selector axles/barrels/drums (for traditional A1 positions or the new A4 short throw)
- Does not require an auto carrier or insert
- Does not require receiver machining or modification
Compatibility:
The FRT-MR3™ is specifically engineered to operate with the factory semi-automatic bolt carrier group (BCG) used in the HK MR556 and HK MR223 platforms. Therefore, the FRT-MR3™ is only compatible with the original, factory-supplied semi-auto BCG (or an in-spec clone) but will not function as intended with a 416 auto bolt carrier or BCG.
Note: The FRT-MR3™ is not compatible with BRN4 full-auto bolt carrier groups.
Construction And Materials:
Crafted in the USA from high-quality materials, including 7075 anodized aluminum and heat-treated 4140 and S7 steel, the FRT-MR3™ is built to endure heavy use. This robust construction ensures reliability and longevity. Like HK always says, "Keine Kompromisse" (No Compromises).
