Frequently Asked Questions
Will this buffer tube assembly work with any A2 fixed buttstock?
Yes. This Luth-AR kit is designed to be compatible with standard A2 fixed buttstocks that accept a rifle-length buffer tube. It follows mil-spec dimensions, so it should fit most commercially available A2-style fixed stocks without modification. Always verify your specific stock's fitment requirements before installation.
Can I use this buffer assembly with calibers other than .223/5.56?
This kit is specifically designed and optimized for .223/5.56 NATO AR-15 builds. While the tube itself is physically compatible with other rifle-length AR-15 platforms, the included standard buffer and spring are tuned for .223/5.56 cycling pressures. For other calibers or special-purpose builds, you may want to consult a gunsmith to ensure appropriate buffer weight and spring tension.
Does this kit include everything needed to complete the buffer system?
Yes — this all-in-one kit includes the A2 rifle-length buffer tube, the standard .223 rifle recoil spring, and the standard rifle buffer body assembly. These three components make up the complete buffer system. You will still need an A2 fixed buttstock, stock screw, and lower receiver end plate and castle nut (if not already installed) to fully complete your lower assembly.
