Frequently Asked Questions
Will this buffer tube kit work with my AR-15 lower receiver?
No — this kit is specifically designed for AR-10 and .308-platform rifles. The buffer, spring, and tube dimensions are calibrated for the heavier bolt carrier group and greater operating pressures of the .308 cartridge. Installing .308 components on an AR-15 lower is not compatible or recommended. Always verify your lower receiver is an AR-10/.308 pattern before ordering.
Which A2 fixed buttstocks are compatible with this buffer tube?
This kit is compatible with standard A2-style fixed buttstocks designed for rifle-length .308 buffer tubes. Most mil-spec pattern A2 fixed stocks from major manufacturers will fit correctly. If you are unsure whether your specific stock is compatible, check that it is rated for a .308/AR-10 rifle-length tube before installation.
Do I need any special tools to install this buffer tube assembly?
Installation is straightforward and generally requires only an armorer's wrench to properly torque the buffer tube onto the lower receiver, along with a castle nut and end plate (sold separately if not included with your lower build kit). No advanced gunsmithing skills are needed, making this an excellent upgrade or replacement kit for DIY builders completing an AR-10 build.
