White Label Armory Master Parts Kit Features The White Label Armory Master Parts Kit is built for the builder or armorer running multiple AR15/M16 projects at once bringing together a deep selection of small parts in one package instead of piecing together several smaller kits. This consolidated approach saves time sourcing individual pins springs and detents separately and keeps a well-stocked bench ready for whatever repair or build comes next. Every component is made in the USA reflecting White Label Armory s commitment to domestic manufacturing and quality control. For builders managing several rifles having a master supply on hand reduces downtime between projects. White Label Armory suggests verifying that the included components match a specific platform configuration before starting a build since AR-pattern rifles vary across generations and manufacturers. Checking fitment against an existing receiver and hardware ensures a smooth installation without surprises. Builders looking for a narrower starting point can step down to White Label Armory s Stage 1 Builder s Essentials Kit or Stage 5 Complete Lower Parts Kit instead. For a shop or dedicated hobbyist stocking up for the long haul the Master Parts Kit offers the broadest single-package solution White Label Armory sells at GrabAGun.
