Building or maintaining an AR-15 means keeping track of small parts that are easy to lose and surprisingly hard to replace when you need them. The CMMG AR-15 lower receiver pins and springs parts kit gives you 17 essential components in one organized package — everything you're likely to need to assemble a lower receiver or repair one that's given up a spring or pin to the workshop floor. Whether you're in the middle of a first build, restocking your spare parts bin, or dealing with a lost detent that disappeared into the void, this kit covers the common culprits.
Lower receiver assembly involves more small springs and pins than seem necessary until one goes missing and you're staring at a parts diagram trying to figure out which way it goes back in. CMMG's kit bundles the trigger spring, hammer spring, takedown springs, disconnector spring, safety selector spring, bolt catch spring, and all the pins and plungers that hold everything together. It's the kind of kit that pays for itself the first time you don't have to order individual parts or wait on a single missing component to complete a build.
Keep a kit in your parts drawer, throw one in your range bag, or grab it as insurance if you're sourcing components for an AR build. These are standard AR-15 lower receiver parts — not exotic or caliber-specific — so once you've got them, they work with any mil-spec lower you run. No guessing whether you bought the right thing; CMMG has already done the legwork of assembling exactly what you actually use.
