Brownells Buttstock Screw, Black

The Brownells M16A1 buttstock screw is an essential component for enthusiasts and restorers of early AR-15 and M16A1 rifles. Specifically designed to accommodate the unique requirements of the original A1 rifle buttstock this screw is shorter than the more commonly used M16A2 screw. Its precise length ensures that it does not extend into the buffer tube, thereby preventing any interference with the buffer's movement. This eliminates the necessity for a spacer between the buttstock and the buffer tube, also known as the receiver extension. Ideal for use with original AR-15, M16, M16A1, SP1 and similar rifles, the Brownells M16A1 buttstock screw is a must-have for maintaining the authenticity and functionality of your classic firearm.Hardened steel, precision machinedMatte black phosphate coating with enhanced durabilityEquipped with a white thread locker patch on the threads to prevent the screw from loosening during operationThe central aperture facilitates airflow during firing and enables water drainage if the rifle is submergedIncompatible with subsequent, extended A2 buttstocks
