Frequently Asked Questions

What are the main components included in a typical A2 Fixed Buttstock Kit for an AR-15?

A standard A2 Fixed Buttstock Kit usually includes the stock itself, a buffer tube (receiver extension), a buffer spring, a buffer, a spacer nut, and a long screw for securing the stock to the buffer tube.

What tools are needed to install an A2 Fixed Buttstock Kit on an AR-15?

For installing an A2 Fixed Buttstock Kit, you'll typically need a 17mm wrench (or similar size), a screwdriver with interchangeable bits, and potentially a vice for stability when tightening the buffer tube.

What is the purpose of the spacer nut in an A2 Fixed Buttstock Kit?

The spacer nut, often referred to as a castle nut or end plate, is part of the buffer tube assembly. It helps to properly align and secure the buffer tube to the AR-15 lower receiver and provides a surface for the stock to rest against.

Are there any specific torque specifications for tightening the AR-15 buffer tube?

While there isn't a precise torque specification, the buffer tube should be tightened until it is snug. Overtightening can damage the receiver, while undertightening can lead to looseness and potential malfunctions.
