The M4-177 with the stock collapsed.
Recently Crosman Corporation brought out a new air rifle – the Crosman M4-177 Pneumatic Air Rifle. As the “M4” in the name strongly implies, this new rifle looks like a tactical carbine, the same look that a lot of powder-burning varmint rifles have adopted in recent years.
The M4-177 is a .177 caliber multi-stroke pneumatic air rifle capable of launching both .177 pellets and .177 BBs. Almost all the visible parts of the M4-177 are molded of engineering polymer. Not surprisingly, it weighs just 3 lbs 9 oz and stretches just 30.3 inches from end to end with the stock collapsed, and 33.75 inches with the stock fully extended.

At the extreme aft end of the M4-177 is corrugated butt plate that has slots top and bottom for attaching a shoulder strap. A lever underneath the adjustable stock allows to be slid in and out to adjust the length of pull (LOP – from trigger blade to butt plate) to the shooter’s preference. The LOP can be as short as 9.75 inches or as long as 13 inches.
Forward of the butt stock is the black polymer receiver which has a black polymer pistol grip attached below it at roughly a 45 degree angle. On the left side of the receiver is a tab that can be rotated sideways to allow a generous supply of BBs to be poured into the M4-177 and a BB retainer button.
The hole into which up to 350 BBs can be poured.
Ahead of the pistol grip is the trigger guard which surrounds a black plastic trigger and which houses a push-button safety. Forward of that is a magazine housing. The faux magazine can be dropped out of the housing, and serves as a storage place for the 5-shot pellet clip and the tool for adjusting the front sight.
The faux magazine serves as a storage place for the pellet clip and the front sight adjustment tool.
Forward of the magazine is the forearm, which serves as a grip for holding the M4-177 while shooting and also as a pumping arm for charging the multi-stroke pneumatic action. Toward the front end of the forearm, on the underside, there is a short section of Picatinny rail which could be used for attaching accessories such as a laser or a flashlight.
The front sight attaches to the Picatinny rail near the muzzle.
Beyond the end of the forearm, you’ll find the barrel, which has a plastic molding on it that provide Picatinny rail sections top and bottom. The post type front sight clamps to the top section of Picatinny rail. Moving back along the barrel, you’ll find another section of Picatinny rail on top of the receiver. The peep type rear sight (which has two different apertures and flips from one to another) clamps to this section of rail or a scope can be mounted. On the right side of the receiver, you’ll find the bolt for cocking the action and a slot for inserting the 5-shot pellet clip.

Adjusting the sights on the M4-177 is a bit unusual. For elevation adjustment, use the special tool stored in faux magazine to move the sight up or down as needed. For windage adjustment, you’ll need a screwdriver to move the rear sight left or right as required.
The rear sight attaches to the Picatinny rail on top of the receiver.
To load BBs into the M4-177, slide the BB loading port cover to one side, pour in up to 350 steel BBs, and slide the port cover back to its original position. Next, push the BB retainer button forward (toward the muzzle), point the barrel at the ground and twist and shake the air rifle to until the “visual magazine” on the left side of the receiver is filled. Push the BB retainer button back toward the butt stock to keep the BBs in the magazine. Insert the empty pellet clip into the breech slot so that the bolt will pass through one of the pellet chambers. Pump the M4-177 at least 3 times but not more than 10. Pull the bolt all the way back (two clicks) and push it forward again. The magnet on the end of the bolt will pick up a BB from the BB magazine and slide it into the barrel.
Squeeze the trigger. The first stage comes out at 3 lb. 13.4 oz. At about 4 lb. 14 oz., the shot goes down range. At ten pumps, the M4-177 launches steel BBs at around 650 fps. I found that’s enough to blow through both sides of a soup can at 13 yards.
Loading pellets requires inserting 5 pellets into the 5-shot clip (make sure the M4-177 is empty of BBs first). Pump the M4-177 up to ten times, pull the bolt back, slide the clip into the breech until it reaches the first detent, and slide the bolt forward again. Pull the trigger. At 10 pumps, the M4-177 launches Crosman Premier 7.9 gr pellets at about 625 fps and delivered a one-inch edge to edge 5 shot group at 13 yards from a sitting position under relatively lousy conditions. Good enough, I think, for terminating pests in the garden at short range.
In the end, I liked the M4-177. It’s fun to shoot and will definitely put a smile on someone’s face on Christmas morning. For an airgun that will probably sell for under a hundred bucks, that seems like a pretty good deal to me.
Til next time, aim true and shoot straight.

That safety thing . . . again
Thanksgiving is just a few days away.
For me, Thanksgiving is the time of year when I take stock of my situation, and – more to the point – all the things that I have to be thankful for. I have been truly blessed. I have many things for which to give thanks, and I hope that you do too.
One of the things that I am thankful for are the folks who read this blog. I am grateful for your readership, your comments, and your feedback. And when you like one of my goofy shooting challenges . . . well, that’s the icing on the cake. So thank you, and keep reading!
The year is rapidly rolling toward the holiday season, and with visions of new airguns dancing in my head, I expect that some of you will receive new airguns for Christmas, and some of you will give new airguns for Christmas. With that in mind, I feel honor-bound to remind all of you that as airgunners our first concern should be for safety.
The basics are pretty simple:
- Never point an airgun at anything you don’t want to see broken or destroyed, injured or killed . . . ever.
- Treat all airguns as loaded even when you “know” they are not.
- Keep your finger out of the trigger guard until ready to shoot and when you are loading your airgun.
- Shoot at a pellet trap or other safe backstop. Don’t use a hard backstop with BBs.
- Make sure everyone on the firing line is wearing eye protection.
- If you are hunting or controlling pests, make certain you know where your pellet will go if you miss. If you are not certain, don’t pull the trigger.
The following is special to parents or anyone else who is involved with children shooting airguns.
Airguns are not toys. They are real air rifles and air pistols and can be dangerous if not handled properly. Your child needs to understand the difference between an airgun and a toy gun is like the difference between a toy car and a real car.
Remember and observe the number one rule of airgun safety: never, ever point your airgun at anything you don’t want to see a hole in, including any person, any animal (except for hunting) or someone else’s property. When the airgun is not aimed at an appropriate target, keep it pointed in a safe direction, such as at the ground.
If you have any doubt that your children and anyone who is with them will observe Rule One, supervise their shooting. If you are not completely certain that they will always handle the airgun safely, supervise them, regardless of age.
Supervision means being close enough to control or redirect the airgun if it is pointed in an unsafe direction. It only takes a moment for a mishap to occur. Be close enough to prevent that from happening – no more than an arm’s length away.
Maintain control of the airgun when it is not being used, including at the beginning and end of each shooting session. Don’t load it and leave it unattended. Store your airgun, unloaded, where it cannot be used by curious youngsters or unauthorized persons. Store the ammunition separately.
Til next time, aim true and shoot straight.

The FX Gladiator Mk II – Part II
in Airguns
as air rifle, Airguns, FX, pcp, pellet gun
The left side of the Gladiator Mk II
To ready the Gladiator Mk II for shooting, attach the filling probe to a SCUBA tank or high pressure pump, slide it into the filling port at the end of the forward air tube, and slowly fill the Mk II to 220 bar.
The spring-loaded 12-shot magazine is self-indexing.
Next, load the rotary magazine. You’ll notice that the Gladiator now uses the same magazines as the FX Royale. Start by turning the transparent lid to the magazine counterclockwise until it stops. Put one pellet in the open slot on the rear side of the magazine so that the tip of the pellet is pointing out of the hole. This locks the magazine spring in place.
Turn the magazine so that the transparent lid is facing you. Turn the lid clockwise one slot at a time and fill the slots with pellets with the tip of the pellets facing into the hole. Lock the lid in its starting position.
When selecting scope mounts, make sure they are high enough to provide clearance for the magazine.
Next, pull the bolt lever all the way back and insert the magazine, black side toward the muzzle, into the breech from the right side. Now, this is where life got interesting for me while testing the Gladiator Mk II. When I mounted the first scope, the magazine hit the “saddle” of the scope (the bulge where the elevation and windage knobs are mounted) when I tried to slide the magazine into the breech. So, down into the workshop again and I mounted another scope. This one slide into the breech slot, but I couldn’t get the bolt to work properly. I called Airguns of Arizona, and Kip helpfully walked me through the process until I could finally figure out that the magazine was hitting the tube of the scope so that it couldn’t be seated all the way home (almost, but not quite). Finally, a third scope with higher mounts fit properly, and the magazine slid into place.
Push the bolt forward, flick off the safety, and squeeze the trigger. The first stage required only 9 ounces on the sample that I tested. At 1 lb. 2.2 oz., the shot went down range. This a phenomenal trigger, light and crisp, that feels a lot like a match trigger.
On high power, the Mk II launches 18.1 gr. JSB pellets at average of 855 fps, or 29.38 foot-pounds of energy at the muzzle; medium power, 655 fps and 17.24 fp, and low power, 499 fps and 14.42 fp. The good folks at Airguns of Arizona tell me that the Mk II will deliver 95 shots per fill on high power and an astonishing 190 shots on lower power.
At 30 yards, shooting from a casual rest, the Mk II delivered this nice group.
And the accuracy? Well, the accuracy is just fine. At 30 yards with JSB Jumbo pellets, I put 5 shots into a group that measured just .625 inch edge to edge. That works out to well under half an inch center to center.
Yup, if I were in the vermin control business and needed an air rifle that required a minimum of ancillary equipment for a day’s shooting, I think the FX Gladiator Mk II would be number one on my list.
Til Next time, aim true and shoot straight.
