TacFire MAR039 AR-15 Mil-Spec Castle Nut Steel Black

TacFire Castle Nut Features The TacFire Castle Nut is machined from steel to mil spec dimensions giving AR-15 builders a reliable part for securing the buffer tube to the lower receiver. Proper torque on this nut is critical to keeping the stock system tight and free of wobble and this castle nut is built to handle that stress without stripping or deforming. Its black finish matches factory hardware so it blends in cleanly on a build using standard finishes. Compatible specifically with AR-15 pattern buffer tubes it is a straightforward replacement or spare part for builders and armorers. At 1.375 inches long and 2.50 inches wide the nut is sized to mil spec AR-15 buffer tube threading and will interchange with most adjustable and fixed stock setups. Keeping a spare castle nut on hand is useful for builders who frequently swap stocks or buffer tubes between projects. Steel construction ensures the nut holds up to repeated torquing and removal without rounding off its notches. For AR-15 owners and builders in need of a dependable replacement part the TacFire Castle Nut is available for sale at ARMSAGORA.
