CMMG AR-15 Survival Kit - Essential Pins and Springs Set

The CMMG AR-15 Survival Kit is a comprehensive assortment of pins, springs, and small parts designed to keep your rifle running downrange and at the range. Whether you're a competitive shooter, hunter, or just want peace of mind, having these essential components on hand means you're ready to handle field repairs without waiting for a gunsmith or a trip to town. Throw this kit in your range bag, truck, or gear locker and know you've got the small stuff covered.

AR-15 platforms depend on dozens of tiny but critical parts working together. A lost pin, a worn spring, or a bent detent can sideline your rifle at the worst possible moment. This kit includes the springs and pins you're most likely to need in a pinch—extractor springs, ejector springs, hammer springs, trigger springs, and the full lineup of pins from takedown to disconnector. It's not a complete build kit, but it's a survival kit in the truest sense: the stuff that actually fails or gets lost in the field.

CMMG designed this set around real AR-15 field failures and maintenance. You get multiples of the parts that wear or disappear most often—two ejector/selector springs, two disconnector springs, two takedown/pivot pin detents, two carrier key screws, and three gas rings. The kit rounds out with firing pin components, extractor hardware, cam pin, and receiver pins. It's compact enough to stash but complete enough to handle most common malfunctions or worn-out component replacements without swapping out your whole gun.

Frequently Asked Questions

What AR-15 platforms does this kit work with?

The CMMG AR-15 Survival Kit contains standard parts compatible with mil-spec AR-15 rifles. Consult your rifle's manual or a gunsmith if you have a proprietary or specialty platform, as not all parts may fit.

Is this kit enough to build or repair an entire AR-15?

No. This kit contains the small springs, pins, and detents most likely to wear, break, or get lost during field use. It's designed to address common failures and malfunctions—not to replace a complete parts kit or lower receiver assembly.

What should I keep this in?

The kit is compact enough for a range bag, truck glove box, or gear pack. Consider a small compartmentalized box or plastic bag to keep the springs and tiny pins organized so you can quickly find what you need.
