Luth-AR® AR-15 Complete Field Repair Parts Kit – Mil-Spec Master Pack – AR-FRK
The Luth-AR® AR-15 Field Repair Kit (AR-FRK) is an absolute multi-component insurance policy designed to shield shooters from the ultimate range-day heartbreak: component wear or a lost spring. No matter how premium your custom rifle build is, mechanical moving elements wear down, firing pins degrade under repetitive thermal cycles, and miniature detent springs have a frustrating habit of launching across the garage floor during bench maintenance. Packaged by the armorers at Luth-AR (812058031628), this tactical field kit bundles the most common high-wear, mission-critical replacement components into a single emergency package.
Every small pin, spring, and plunger contained inside the AR-FRK framework is manufactured to strict United States military-specification dimensions, providing direct drop-in functionality for any standard AR-15 lower receiver or 5.56 NATO/.223 Rem bolt carrier group (BCG). Rather than focusing on just a single assembly, this comprehensive repair pack targets both the **fire control group and the critical internal extraction matrix of the bolt head**. It includes a premium, heat-treated firing pin, a complete extractor reconstruction group (pin, spring, insert, and extractor claw), and crucial fire-control springs like the hammer, trigger, and disconnector coils. Tossing this compact package into your range bag or duty pack guarantees that a broken pin or worn extractor will never sideline your rifle during a high-stakes training class, competitive match, or hunting excursion.
Includes: (1) Firing Pin, (1) Firing Pin Retaining Cotter Pin, (1) Extractor, (1) Extractor Pin, (1) Extractor Spring with Buffer Insert, (1) Ejector, (1) Ejector Spring, (1) Mil-Spec Hammer Spring, (1) Mil-Spec Trigger Spring, and (1) Disconnector Spring.
