Manual

2. When attempting to free a jammed cartridge, do not use any type of tool that is likely

to act as a “firing pin” and discharge the cartridge should the tool impact on the

primer. Never use a cartridge as a “tool.”

3. After clearing a jam, inspect the gun mechanism to determine if dirt or debris might

be the cause of the problem. Excess lubricant or grease can cause cartridges to feed

sluggishly. An accumulation of grease, dirt or powder grains in the magazine can

contribute to cartridge feeding problems.

4. After clearing a jam, inspect all cartridges that have been removed from the gun.

Safely dispose of any cartridges which are dented or nicked or have bullets that are

loose or improperly positioned in the cartridge case.

5. If it appears that the gun and magazine are not at fault and that the jam was caused

by the type of cartridge being used, then try another type or brand of cartridge.

6. If the above procedures do not result in a smooth and reliable feeding firearm, don’t

use the gun until it feeds cartridges smoothly and reliably. The rifle should be

returned directly to our Newport Product Service Department for repair. See the

“Service and Parts” section p. 33, for packing and shipping information.

Another precaution: Form the habit of examining fired cartridge cases from time to

time. If fired cases have bulged heads or show splits on any part of the case, stop using

that ammunition. If the problem persists with different types of ammunition, return the

rifle to the factory for inspection. (See page 33.)

7. If a cartridge or shell is caught between the bolt carrier and receiver, put the safety on

“SAFE,” retract the bolt carrier using the charging handle, and lock it in the open

position using the bolt catch. Remove the magazine; then remove the jammed case.

8. If a fired

case is in the chamber, use a cleaning rod to knock it out.

9. If an unfired cartridge is stuck in the chamber, keep the muzzle pointed in a safe

direction with the safety in the “SAFE” position. Close the bolt, disengage the take

down pin, remove the bolt and carrier (see “Disassembly” p. 24, steps 3 & 4), and

remove the unfired cartridge from the breech-end rather than trying to dislodge it

with a cleaning rod inserted from the muzzle. Use a piece of 3/16” brass rod which

has one end shaped like a screwdriver tip. Insert the tip in the extractor groove of the

cartridge, use the face of the ejection port as a fulcrum and carefully pry out the

cartridge. Be careful not to strike the primer area of the live cartridge! Vigorously

brush-clean the chamber with solvent after clearing any jam involving the chamber.

TO MINIMIZE MALFUNCTIONS (“JAMS”)

Autoloading firearms of all makes and types occasionally malfunction when a cartridge

fails to feed from the magazine to the chamber, or when a cartridge (or fired case) fails

to properly extract and eject.

To minimize the possibility of such occurrences the gun user should:

1. Use ammunition of the correct caliber 5.56mm NATO or .223 Rem. and type which is

loaded to Industry Specifications. Avoid reloads, remanufactured cartridges, and

cartridges that are dirty, corroded, or deformed. (See “Warning - Ammunition,” p. 11.)

2. Clean and lubricate the gun in accordance with the instructions in this manual.
