XTS Complete Lower Parts Kit Features The XTS Complete Lower Parts Kit contains every component needed to finish an AR15 lower receiver from the trigger group to the small pins and detents that are easy to overlook but essential to function. Including a fire control group means builders do not need to purchase a trigger assembly separately simplifying the parts list for a first-time or budget-conscious build. A 301 rubberized AR grip rounds out the kit giving the finished rifle a comfortable textured grip surface right out of the box. The black finish matches standard AR15 hardware keeping the completed lower looking factory-correct. Because this kit is comprehensive it suits builders assembling a complete lower receiver from a stripped lower without having to track down individual springs pins and small parts from multiple sources. That completeness reduces the risk of a build stalling out due to a missing detent or spring partway through assembly. The included grip also saves an additional purchase and installation step for builders who have not already selected aftermarket furniture. For AR15 builders looking for a single complete parts kit to finish their lower the XTS Complete Lower Parts Kit is available for sale at GrabAGun.
