WARNING – SUSTAINED FIRING

TO LOAD AND FIRE (WITHOUT MAGAZINE)

The rifle can be used as a single shot rifle in the absence of a magazine or for

safety or training purposes. To do so, follow steps 1 and 2, p. 14. Then, manually

load a cartridge into the chamber, and follow steps 5 and 6, p. 14, disregarding

the magazine. Note that the bolt will not automatically lock open after the

cartridge is fired and automatically ejected. The regulator may be set to “0” (see

p. 27) to require manual ejection of the spent cartridge (the spent cartridge may

be difficult to extract manually). Engage the safety between shots.

HOT BARREL CAN

“COOK-OFF” (FIRE)

CARTRIDGE IN CHAMBER

The SR-556 rifle fires from a

closed bolt. Sustained firing can

create excessive heat in the barrel

and can cause “cook-off” of

ammunition (heat-firing of the

cartridge in the chamber). This

“cook-off” can occur a substantial

period of time after firing has

ceased. Always unload the firearm

and unload the chamber

immediately after you have

finished shooting.

WARNING – UNLOADING

TO UNLOAD

WARNING: This sequence must be followed exactly as spelled out. Failure to do

so can result in the rifle’s chamber becoming unintentionally loaded with a

cartridge!

1. Keep the muzzle pointed in a safe direction at all times and keep the fingers

outside the trigger guard. Rotate the safety to the “SAFE” position.

So that the rifle can be used as a single loader, it

will fire whether or not a magazine is in the gun

if a cartridge is chambered. Removing magazine

does not unload rifle! To unload, first

remove

magazine, then

pull the charging handle to the

rear, eject chambered cartridge, and visually

inspect chamber. The safety should always be in

the “SAFE” position when loading or unloading

the rifle.

GUN WILL FIRE WITH

MAGAZINE OUT
