XTS Lower Parts Kit Features The XTS Lower Parts Kit supplies the small components needed to bring a stripped AR-15 lower receiver to life covering everything short of the fire control group and grip. The bolt catch kit and magazine catch kit handle two of the most frequently manipulated controls on the rifle so having correctly sized reliable parts in the build matters for long-term function. Takedown and pivot pin sets each with their detents and springs let the upper and lower receivers separate and pivot smoothly for cleaning and maintenance. A buffer retainer pin and spring round out the kit s coverage of the buffer tube interface keeping that connection secure under recoil. An ambidextrous selector with its detent and spring gives builders the option to configure the safety for right or left-hand operation without sourcing a separate part. Hammer and trigger pins along with the hammer trigger and disconnect springs are included for builders pairing this kit with their own fire control group. Finished in black to match standard AR-15 hardware the kit is aimed squarely at gun enthusiasts and builders assembling a lower receiver from scratch. It is a comprehensive cost-effective way to complete a build without hunting down individual small parts one at a time.
