BLACKHAWK! ADJUSTABLE CARBINE RIFLE BUTTSTOCK - Manual (Page 2)

INSTALLATION INSTRUCTIONS:
1. With the rifle pointing in a safe direction and your fingers outside the trigger guard, remove the magazine, open the bolt and both
visually and by touch, make certain there is not a cartridge in the chamber.
2. WARNING: Prior to installing stock verify that you have purchased the correct stock to fit your receiver extension tube. Confirm that
you have either a “Commercial” receiver extension (Fig A.) or a “Mil-Spec” receiver extension (Fig B.). To determine your receiver
extension tube size simply measure the diameter of the tube. It is crucial that you have purchased the correct size stock. If you have
purchased the correct size tube it should slide fairly easily over the tube and not fit too tight or not have too much wobble. If the stock is
extremely tight DO NOT force the stock onto the tube. DO NOT FORCE a Mil-Spec stock onto a Commercial sized rear extension.
Forcing the stock onto the tube may damage the extension tube or the stock. If you have purchased the incorrect stock, contact
BLACKHAWK! Customer Service for an exchange.

extension. (Figure C)

length and release lever. Locking pin will automatically engage or “click” into nearest corresponding locking hole. To ensure engagement
of locking pin, push or pull on rear portion of stock. NOTE: At the shortest length setting, some different Commercial sized rear extension
tubes will protrude slightly out rear of stock. To avoid simply adjust the stock to next longest setting.
