Brownells M16A1 Buttstock Screw

Description

Product Overview

The Brownells M16A1 buttstock screw is the correct short screw for installing an original A1-pattern buttstock on early AR-15, M16, M16A1, and SP1 rifles. It’s sized to stay clear of the buffer tube so it won’t interfere with buffer movement.

Key Features

• Short A1-length screw designed to avoid protruding into the buffer tube and interfering with buffer travel
• Eliminates the need for a spacer between the buttstock and the buffer tube
• Precision-machined hardened steel construction for durability
• Matte black phosphate finish for corrosion resistance
• Center hole supports airflow during firing and helps drain if the rifle is submerged
• Not compatible with later, longer A2 buttstocks

Get the right screw for an A1-pattern build so your surplus or reproduction buttstock installs correctly and functions as intended.
