Type: Pellet/BB Multi-pump Air Rifle.
Materials: Plastic with some metal.
Weight: 3.6 pounds.
Barrel: 16.75 inches, rifled.
Action: Single shot - bolt action with manual advance magazine.
Ammunition Type: .177 caliber pellets & 4.5mm steel BB's.
Ammunition Capacity: 5 shot pellet magazine - 18 shot BB internal BB magazine - 350 round BB hopper.
FPS: Up to 495 in Canada and 600 fps in the US.
Trigger Pull: The trigger pull on the Crosman M4-177 is medium length and fairly light. The trigger mainly releases the bolt so no pre-cocking is required. It takes a bit to get used to where the release point since there are no real warning indicators. The trigger is plastic but seems to work just fine as there is no real load on the trigger when shooting.
Accuracy: I found the Crosman M4-177 Air Rifle to be a very good shooter, getting about a 3/4 inch grouping from 30 feet out in a semi rested position (sand bag up front, standing in the back). I also put 3 rounds through my Chrony Chronograph and the M4-177 averaged about 410 fps with the 10 pump maximum which is about what I would expect from the Canadian detuned version, keep in mind the US non-detuned version shoots up in the 600 fps range so it would have been nice if the Canadian version got closer to our legal non-registered limit of 500 fps.
Build Quality: The Crosman M4-177 Multi-pump Air Rifle is mostly plastic which some of my viewers will not like, but for a sub $100 Replica Air Rifle it hits the mark in terms of affordability and if it was an all metal airgun you would more than likely expect to double the price tag - if not more! Even though plastic is used throughout the Air Rifle, there are some internal metal parts where they need to be, the fit and finish is very good and I do not get the feeling that the Crosman M4-177 is cheaply made in any way.
Realism: The Crosman M4-177 is a respectable M4/AR replica. It is not exact in terms of true dimensions as the forward stock is a bit long to accommodate the pumping mechanism, (kind of long like the original AR but without the tapering). Crosman did a good job to add all the parts that you would find on a real M4/AR even if they are simply for show and are molded into the plastic. I particularly like the removable iron sights and full rail for mounting a scope or red dot sight. I am also really glad to see a Replica Assault rifle on the market as so few of them are available in pellet or steel BB shooters.
Available in the: Replica Airguns Store.
- One of the few replica Air Rifles on the market (MP5K PDW & Mini UZI).
- Very well priced.
- Excellent accuracy!
- Comes with detachable and adjustable iron sights.
- Fully adjustable stock.
- Picatinny rail on top for just about any type of sight system.
- Option of shooting pellets or BB's.
- Mostly plastic build.
- Lower rails you just can not use as the pumping action gets in the way?
- FPS is well below the Canada non PAL limit of 500 fps so maybe a bit too detuned?
The Crosman M4-177 Multi-Pump Pellet/BB Air Rifle is in my opinion a must have air rifle, simply because... why not? How many replica pellet and steel BB shooting air rifles are there out there and for under $100 to boot? What the M4-177 lacks in metal parts, it makes up in accuracy and fun factor. And the M4-177 really is not a bad replica in terms of realism as Crosman made it a point to copy the real steel M4/AR fairly closely. I know for a fact from the emails I received and YouTube comments that many people have been looking for an M4/AR styled Air Rifle and Crosman has now delivered one to us so what are you waiting for ;)
