WARNING: Keep the airgun in the “ON SAFE” position until you are actually ready to shoot. Failure to follow these instructions may result in serious injury or death.

2. Operating the Safety

The words PRESS FIRE and PRESS SAFE are on the top of the trigger guard. The	“ON SAFE”	“OFF SAFE”
PRESS FIRE and PRESS SAFE indicate the safety condition when pressed flush
with the trigger guard (Fig. 2).

A.To Put the Airgun “ON SAFE”:

• Locate the safety directly in front of the trigger.

• The safety is ON and the airgun is “ON SAFE” when the safety button is pushed from the left to the right (No Red Showing)(Fig. 1A).

B.To Take the Airgun “OFF SAFE”:

• The safety is OFF and the airgun is “OFF SAFE” when the safety button is pushed from the right to the left (Red Showing)(Fig. 1B).

• When the airgun is “OFF SAFE,” the trigger can be pulled and the airgun can be fired if it is charged (filled) and loaded.

Like all mechanical devices, an airgun safety can fail. Even when the safety is “ON SAFE”, you should continue to handle the airgun safely. NEVER point the airgun at any person. NEVER point the airgun at anything you do not intend to shoot.

3. Pumping the Airgun

WARNING: Always hold the forearm firmly when pumping the airgun. Failure to grip the forearm firmly while pumping the airgun may cause the forearm to spring back into the closed position and may result in injury.

WARNING: Never pump your airgun more than 10 times. Overpumping may leave a small amount of air in the airgun after it is fired and may allow the user to fire a second shot without additional pumping. Failure to follow these instructions may result in serious injury or death.

CAUTION: Never pump your airgun more than 10 times. Overpumping can cause major damage
to your airgun.
Note: You must follow the procedure described below for pumping, loading and firing your airgun
each time you shoot.
• Put the airgun “ON SAFE”. (See Step 2A)
• Place your hands in the same positions shown in Fig. 2. Improper hand placement may result in
pinching if you lose hold of the forearm and may result in injury.
• Firmly grip the forearm and open it all the way until it stops (Fig. 3) and then, with a smooth
stroke, return the forearm to its original closed postion.	Fig 2
• Use straight strokes while pumping the airgun. Twisting the forearm while pumping may cause
the forearm to break.

•Make sure to use at least three pumps (but no more than 10) to prevent a pellet from jamming in the barrel after firing.

Reminder: You must follow the procedure described above for pumping, loading and firing your airgun for each shot.

4. Loading and Unloading BBs
Your airgun was designed to work with Crosman branded ammunition. These include CROSMAN,
COPPERHEAD, and BENJAMIN. Use of other ammunition may cause your gun to malfunction.	Fig 3

• Tilt the airgun (barrel downward), pointing in a SAFE DIRECTION.
• Pull the bolt all the way back (two clicks) and then slowly forward looking to see if there is a BB on
the magnetic bolt.
• If your airgun is not pumped, follow section 3 on pumping your airgun.
• Point the airgun in a SAFE DIRECTION; take “OFF SAFE” (See Step 2B) and fire. This will
unload the BB from the magnetic bolt.
• Repeat this unloading procedure until no BBs are visible on the magnetic bolt.
REMEMBER: BBs will not transfer from the magazine to the barrel if the airgun is tilted upward.
To remove BBs from reservoir - open loading port cover, turn gun so the hole is facing down and
shake the gun until you no longer hear BBs in the reservoir.
REMEMBER TO ALWAYS TREAT YOUR AIRGUN AS IF IT IS LOADED.
5. Loading and Unloading Pellets
Your airgun was designed to work with Crosman®, Copperhead® and Benjamin® ammunition.			Fig 6

6 Aiming and Firing Safely A. Aiming the Airgun

•Always point your airgun in a SAFE DIRECTION.

•You and others with you should always wear shooting glasses to protect your eyes.

•Do not shoot at hard surfaces or at the surface of water. The BB or pellet may bounce off or ricochet and hit someone or something you had not intended to hit.

•Always choose your target carefully. For example, you may wish to shoot at paper bulls eye targets that are attached to a safe backstop such as the Crosman 0852 PelletTrap (available at crosman.com). A heavy blanket should be hung behind the pellet trap to prevent ricochet

should you miss the backstop.

• Your airgun is designed for target shooting and is suited for both indoor and outdoor use. Always remember to place your target carefully. THINK about what you will hit if you miss the target.

•Follow the instructions for pumping (Section 3) and loading BB (Section 4A) or pellets (Section 5A).

•The airgun is correctly aimed when the front sight blade is positioned exactly in the center of the aperture of the rear sight. The top of the front sight blade should be even with the top of the aperture in the rear sight. The bulls-eye should appear to rest on the top of the front sight. (Fig. 9)

•When you are sure of your target and backstop, and the area around the target is clear, take the airgun “OFF SAFE” (See section 2B) and pull the trigger to fire.

Note: You must follow the procedure for pumping, loading and firing your airgun each time you shoot.

B.Sight Adjustment

•The front sight is adjustable for elevation. Use the tool supplied in the storage magazine to adjust the front sight up or down by turning clockwise or counter clockwise. (Fig 10)

•There are two different rear sight options for the M4-177 depending on which model you purchase.)

Option 1- Removable rear sight (Fig 11)

•This airgun comes with an adjustable rear sight for windage (left or right movement) (Fig 11A) Adjust for windage by turning screw A in the desired direction.

Option 2- Carry Handle (Fig 12)

•This carry handle comes with an adjustable rear sight for windage (left or right movement) (Fig 12A) You can adjust for windage by turning screw A in the desired direction. Use large aperture (Fig 12B) for large or moving targets and the small aperture for stationary and bulls-eye targets. For elevation adjustment use the thumb wheel (12C) to move the sight up or down.

ADJUSTING THE STOCK

•Your airgun is shipped with the stock in the closed position and is capable of adjusting to different lengths.

•Before adjusting the stock make sure your airgun is “ON SAFE”, (see section 2A) and pointed in a SAFE DIRECTION.

•Push the stock release lever and adjust the stock until it locks into the desired position.

7. Removing a Jammed BB or Pellet

• Do not reload the air gun.

• Put the airgun “ON SAFE”.

• Point the airgun in a SAFE DIRECTION.

• If shooting BBs, unload the BBs from the visual magazine (See Step 4B).

• With the airgun “ON SAFE”, open the bolt by pulling it all the way back.

• While pointing in SAFE DIRECTION, hold the gun in the position shown in Figure 13.

• Insert a .177 caliber ramrod (not included) into the barrel and carefully push the jammed BB or pellet out of the gun. Do not try to reuse the BB or pellet.

• If you are unable to unjam your airgun by following this procedure, take no further action and contact an Authorized Service Station for further assistance and service.

8.Maintaining Your Airgun

•Before you attempt to oil your airgun, make sure the gun is “ON SAFE”, unloaded and the air has been removed (see Section 4B and 5B).

• Your airgun will maintain proper function longer if you oil it every 250 shots. Put one drop of

Crosman 0241 Pellgunoil® (available at crosman.com) on the pump
pivot pins and the pump cup in the pump mechanism. (Fig 13)

		ROD
• Close the forearm, point the airgun in a SAFE DIRECTION, take
OFF SAFE, and pull the trigger.
• A light coat of Pellgunoil® on the barrel helps prevent rust.
• DO NOT MODIFY OR ALTER YOUR AIRGUN. Attempts to modify	Fig 13			JAMMED AMMO
the airgun in any way inconsistent with this manual may make your						BOLT OPEN
airgun unsafe to use, cause serious injury or death, and will void
the warranty.

•If you drop your airgun, visually check to see that no damage has occurred to the gun. If anything seems changed, like a shorter or weaker trigger pull, this may mean worn out or broken parts. Call Crosman customer service for assistance before using your airgun again.

9.Attaching Accessories

A. Attaching a Scope (not included)

This airgun has an integrated top rail that is picatinny/weaver compatible for attachment of aftermarket sights, including scopes with picatinny/weaver rings. Adjust the rings on your scope to match the measurements of the top

rail. Then adjust the scope for your desired eye relief. Then tighten the hand knob or screw to make the rings secure to the top rail. DO NOT OVERTIGHTEN THE RING TO THE TOP RAIL. Over tightening the ring on

the plastic rail will cause stress damage to the plastic and may deform the top rail.

B. Attaching a Sling (not included)

• This air rifle has two sling loop slots. One slot is in the stock and the other is under the front sight above and below the barrel.

• To attach the sling at both ends push the sewn webbing loop end through the slot and pull tight. To remove the sling, fold the webbing to its smallest size and push back through the slot until the webbing comes free.

10.Reviewing Safety

•Never point the airgun at any person or at anything you do not intend to shoot.

•Always treat the airgun as though it is loaded and with the same respect you would a firearm.

•Always aim in a SAFE DIRECTION. Always keep the muzzle of the airgun pointed in a SAFE DIRECTION.

•Always keep the airgun “ON SAFE” until you are ready to shoot.

•Always check to see if the airgun is “ON SAFE” and unloaded when getting it from another person or from storage.

•Always keep your finger off the trigger and out of the trigger guard until ready to shoot.

•You and others with you should always wear shooting glasses to protect your eyes.

•If your reading or prescription glasses are not safety glasses make sure you wear shooting glasses over your regular glasses.

•Use the proper size BB or pellet for your airgun. - .177 caliber (4.5 mm) pellet or BB.

•Never reuse ammunition.
