Survivor Systems Professional Collapsible Stock - Black - SSIPROBLK

The Professional Collapsible Stock by Survivor Systems, Inc. has all of the same ergonomic and tactical features of their Option Zero stock but in an adjustable version.

On-board extra magazine storage

This feature is unique to the Option Zero featureless stock and is a big reason why Survivor Systems has been chosen as a preferred supplier by large AR-15 brands and manufacturers. This feature is useful for any situation and allows you to legally double your on-board ammunition capacity. No other featureless stock offers this functionality.

Control and Ergonomics 

The wide, full length comb and full size over-molded butt-plate make this stock feel like a match quality stock. The ability to accept our butt-plate spacers allows for a wide range of length adjustment.

Durability and Ruggedness

Glass filled injection molded nylon along with brass and stainless hardware.

IMPORTANT: This model requires a “Mil-Spec” buffer tube for proper installation.
