Doublestar Corp. Field Repair Kit – AR-15/M16 Essential Maintenance

The Doublestar Corp. Field Repair Kit provides critical replacement parts for AR-15 and M16 pattern rifles when you're at the range or in the field. This compact kit contains commonly worn or broken small parts that can sideline your rifle—firing pin retaining pin, extractor spring, extractor insert, gas rings, and ejector spring. Keep one in your range bag to address minor mechanical issues without cutting your session short or heading to a gunsmith.

All components are mil-spec and manufactured to Doublestar's standards for fit and function. The kit comes organized in a small container that fits easily in a pocket or pack. Installation of these parts requires basic armorer knowledge and punches—gas rings require bolt disassembly, while pins and springs are straightforward field-level replacements. No professional gunsmithing needed for shooters familiar with AR-15 maintenance procedures.
