To eliminate the frustration that non-standard parts can cause, Slide Fire Solutions offers the proven Mil-Spec Buffer Tube assembly. This Buffer Tube is consistently machined along the horizontal axis and has been threaded so that, when installed, the buffer tube is precisely aligned with the lower receiver. This Buffer Tube Assembly provided the best fit and most consistent results in the numerous tubes used during research and development.
Included with each Slide Fire Buffer Tube Assembly is the Spanner Wrench that is required to remove the Castle Nut that holds the existing buffer tube in place. Once the tube is installed, use the Spanner Wrench to tighten the Castle Nut.
