Your "Nylon 66" is a 22 caliber automatic rifle chambered for 22 caliber Long rifle cartridges only. Do not use other ammunition in this rifle.
The safety is operated by the safety thumbpiece located to rear of receiver cover. It is placed on the ON SAFE position when pushed rearward. In this position, the RED dot will not show. When the safety thumbpiece is pushed forward to the FIRE or OFF SAFE position, the RED dot will show and the rifle is ready to fire. The safety is designed to prevent the firing of the rifle when the trigger is inadvertently pulled and is not intended to justify careless or irresponsible handling.
Important- Use of 22 caliber long or 22 caliber short cartridges may cause jamming of cartridge in barrel chamber. Should this occur, special care must be taken in removing jammed cartridge because of the possibility of accidental discharge. Proceed as follows:
Push safety thumbpiece rearward to SAFE position. Turn ejection port in receiver upwards and drop long rifle cartridge into recess against the closed bolt (Fig. 1). Pull bolt handle back quickly and release. Cartridge will then drop into action and load into barrel chamber.
Load cartridges into rear of stock. Capacity is 14 long rifle cartridges. Push safety thumbpiece rearward to SAFE position. Hold rifle with muzzle downward. Reach into butt plate recess and turn magazine plug to unlock magazine tube. Pull magazine tube from stock. Drop long rifle cartridges into magazine tube bullet first. Replace magazine tube and lock in place by turning magazine plug.
Point muzzle in safe direction. Push safety thumbpiece forward to FIRE position (Fig 2). RED safety indicator will show to rear of safety thumbpiece in FIRE position. Pulling trigger will fire each round fed into barrel chamber. After firing, the autoloading action will cock rifle and load another cartridge into chamber.
Push safety thumbpiece rearward to SAFE position. Unlock and remove magazine tube from rear of stock. Turn muzzle upwards and allow live cartridges to empty from magazine. Replace magazine tube and lock in place.
CAUTION: After unloading, pull bolt handle back repeatedly to unload live cartridges from action or barrel chamber. A colored magazine follower should be seen from ejection port when action is empty. Check chamber of barrel from open ejection port to make sure no live cartridge remains in chamber.
Wipe bore with 22 caliber cleaning patch. Wire brush with powder solvent, if necessary, and wipe clean. Use lightly oiled patch after cleaning.
DuPont Nylon is self-lubricating and provides smooth surfaces for free movement of the action. Therefore, cleaning and lubricating is unnecessary for thousands of rounds of firing. After extended shooting or when rifle is to be stored for sometime, only partial disassembly is required for cleaning. Make sure rifle is unloaded. Cock rifle and follow steps one and two as directed on page 1. Remove ejector from exposed left side of rifle. No further disassembly is required. Replace bolt handle. Pull back bolt assembly and hold. Scrape shooting residue from cartridge feed guide and bolt rails in stock.
Clean face of bolt. The metallic action parts of the Remington NYLON 66 will perform best and remain clean longer if little or no oil is used. The nylon parts need no oil. Use oil sparingly on metallic action parts to prevent rust. Always wipe receiver cover and barrel with oiled cloth after handling. Fingers leave invisible "prints" of moisture that can rust steel parts unless removed. No special care of nylon parts is required. After exposure to wet weather, always wipe receiver cover and barrel with oil to prevent rusting. Abrupt changes in temperature cause condensation and wetness, therefore, special care to metal parts is required for rust prevention. When shooting in below freezing weather remove any excess oil and use dry graphite. After cleaning, reassemble parts in reverse order.
Your Remington "NYLON 66" may be adjusted for windage or range purposes by movement of rear sight. The front sight is of "fixed" type, not adjustable, and attached to barrel by two screws. Coin fitted slots assist operation of both windage and range screws. A stop prevents either screw from being removed from the sight. The receiver is designed with two dovetail grooves cut into top panel for attaching "tip-off" type of telescope mounts. The mount may be easily slipped into receiver grooves and tightened in desired position.
Turn range screw clockwise to raise sight. This will raise bullet impact at target or increase range. Turn range screw counter clockwise to lower sight. This will lower bullet impact at target or lessen range.
Screw windage screw clockwise to move rear sight to right. This will move bullet impact at target to right. Screw windage screw counter clockwise to move rear sight to left. This will move bullet impact at target to left.
Rifle should be checked periodically by a competent gunsmith to ensure proper inspection and any necessary replacement of worn or damaged parts
