Luth-AR buffer retainer and spring are made to mil-spec standards and ready to drop-in to any of your AR15 or AR10 lower receivers to replace a lost buffer retainer or spring, or to finally complete a current build. The buffer retainer is designed to retain the buffer inside the buffer tube while it's under spring tension from the buffer spring. Buffer retainers are known for shooting out and getting lost when upgrading, cleaning, or assembling the buffer tube (receiver extension) onto or off the lower receiver. Always helps to have a few spare parts laying around and these are a must-have. Put into a kit with one buffer retainer and one buffer retainer spring for your convenience.
