Rare Breed Triggers Replacement Spring Set for the FRT 15L3 K013 UPC 000000000000
Product Description
The Rare Breed Triggers Replacement Spring Set for the FRT-15L3 (SKU: K013 / UPC: 000000000000) provides operators with the critical wear components needed to maintain flawless cyclic reliability. Purpose-built for the flat-shoe, 3-position forced reset trigger cassette, this kit ensures your firing mechanism maintains correct reset geometry, safe mechanical lockup, and positive hammer strike energy during intense, high-volume strings of fire.
Proudly manufactured in the USA from premium high-tensile spring steel, these direct OEM replacement springs are precisely heat-tempered to resist compression set and fatigue under the severe operational stress of the forced reset cycle. The kit delivers a comprehensive 3-piece factory refresh, including one precisely calibrated hammer spring, one trigger spring, and one disconnector spring, instantly restoring factory-new trigger pull weights and rapid-fire cadence.
Consistent preventative maintenance is vital for high-performance mechanical trigger assemblies. By maintaining a spare K013 spring set in your range bag or armorer's toolkit, you can quickly execute scheduled maintenance or field repairs, guaranteeing your FRT-15L3 remains operationally ready without enduring prolonged downtime.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Exclusively compatible with the Rare Breed Triggers FRT-15L3 (3-position flat shoe model). CRITICAL: NOT compatible with standard Mil-Spec AR-15 trigger groups, the legacy FRT-15 (2-position), or the FRT-15C3 (curved model). Do NOT attempt to alter, stretch, or clip the spring legs to fit unsupported chassis platforms.
- Ensure the host AR-15 is completely clear, the magazine is removed, and the chamber is visually and physically verified empty before beginning any armorer work.
- Separate the upper receiver, push out the receiver's anti-walk pins, and carefully lift the FRT-15L3 cassette from the lower receiver pocket.
- Disassemble the trigger cassette components on a clean workspace, carefully noting the factory orientation of the original hammer, trigger, and disconnector springs.
- Install the new K013 replacement springs, verifying the hammer spring legs rest evenly on the trigger body and that the trigger and disconnector springs seat fully without binding.
- Reassemble the trigger cassette into the lower receiver, secure the anti-walk pins, and perform a comprehensive dry-fire function check across Safe, Semi, and FRT modes before returning the firearm to live-fire duty.
