Armaspec Superlight Lower Parts Kit Features The Armaspec Superlight Lower Parts Kit includes 23 individual components needed to complete an AR-15 lower receiver built around key upgrades over a typical mil-spec parts kit. The Armaspec SFT 45/90 safety selector offers a shorter throw for faster manipulation between safe and fire a detail that matters in both competition and defensive use. Enhanced superlight takedown and pivot pins reduce weight at the receiver while stainless steel takedown and pivot detents along with their springs improve long term durability and smooth operation. A stainless steel anti-walk trigger and hammer pin set along with included hex keys for installation keeps the pins from migrating out of position during firing a common issue with standard mil-spec pins. An enhanced magazine release button paired with the magazine catch and magazine spring gives builders crisp reliable magazine changes while a stainless steel bolt catch and bolt catch detent spring and roll pin ensure the bolt locks back consistently on an empty magazine. A stainless steel buffer retainer and spring complete the buffer tube interface for reliable function. Finished entirely in OD Green anodize the kit gives builders a cohesive upgraded color scheme for a 5.56 or .223 Rem AR-15 build rather than mixing finishes from individual aftermarket parts. For builders assembling a lower receiver who want a complete upgraded parts kit in one box the Armaspec Superlight kit covers the full list of needed components.
