Caldwell AR Field Repair Kit – Essential Spare Parts for AR-15/M16

The Caldwell AR Field Repair Kit contains the most commonly lost or broken small parts for AR-15 and M16 pattern rifles. Designed for shooters who spend extended time at the range or in the field, this kit ensures you have critical replacement parts on hand when a detent, pin, or spring fails or walks off during maintenance. Prevents range trips from ending early due to a missing $2 part.

Kit includes buffer retainer, buffer retainer spring, bolt catch spring, bolt catch plunger, takedown detent, takedown detent spring, safety selector detent, and safety selector detent spring—the exact components that tend to disappear during cleaning or field stripping. All parts are stored in a compact, organized case that fits easily in a range bag or cleaning kit. No gunsmithing required for installation; most parts are simple replacements during routine disassembly.
