Crosman M4-177 Review

Crosman M4-177 Review

Here's the deal: The Crosman M4.177 Air Rifle brings a lot of great features to the table, and if you’ve seen it in detail before, you’ll know that it looks pretty awesome too.

There’s a catch though: The M4 air rifle wasn’t made with a lifetime worth of servitude in mind, well at least not according to the thousands of reviews available online anyway.

After you’ve read our review, you should be able to make an informed decision of whether or not this rifle tickles your fancy.

The Crosman M40-177 Pneumatic Pump Air Rifle - Behind the Scenes


This is something that the Crosman M4 has going for it: it handles ammo like a boss. The rifle operates with a 5-pellet mag strip that runs into the rifle and then places the pellets in place with the bolt action. It’s a system that works, and works pretty well too.

Furthermore, the stock has a slot for 350 BBs that can be loaded into the chamber when you tip the rifle down, flip the switch, and give the gun a little shake to load the BB into the bolt. Odd? Perhaps, but it’s a cool feature nonetheless.

One thing that we appreciated was the fact that the stock is adjustable, so it’s good for being used by a kid and an adult alike.

Design & Build

Essentially, this is where things kind of fall apart. You can actually see where Crosman tried to trim down the price, and it didn’t come out too pretty in the end. The gun is made almost entirely out of plastic materials. Sure it’s not lightweight and flimsy plastic, but plastic is still plastic, and we all know that this material doesn’t hold up to applications we need it to.

Initially, we were impressed by the feel and the look of the Crosman M4, but after a few weeks of testing it out in the field, the air chamber springs started acting up. We were also limited to about 5 pumps per shot for the sake of prolonging its life, but ended up sacrificing a lot of power. All in all, the M4 blows itself out after a few weeks, and we weren’t too happy with the results.


Again we were impressed by the M4’s initial accuracy, just like all its other features. After using 10 pumps for a while however, accuracy just went down the drain. We have to admit that we weren’t using Crosman Brand Pellets all the time, and those tests were more than just a little wobbly. You might have better luck if you use and stick to Crosman Destroyers.

The Sights

This is something that we don’t really have a lot to say about. The sights are rather bland, and jiggle too much to our liking. The other issue is that it’s near impossible to find a scope that fits the M4, since it’s a non-standard design. Catch 22, right?

The Pros

  • When used with the right ammo, it offers        great initial accuracy and good enough            accuracy after extended use
  • The ammo loading options are awesome
  • It looks wicked
  • The design concept is great
  • It has a nifty “magazine” in front that               doubles up as a removable case for storing     small tools and pellet strips

The Cons

  • It’s not durable
  • It’s not accurate after extended use
  • Finding a scope or working sights for this        gun is very hard
Final Thoughts

We appreciate Crosman’s efforts in trying to produce a low-cost air rifle that looks the part, but we just wish it stood up to the demands they claimed it could. The Crosman M4-177 Air Rifle scored a below-average 4 out of 10 in our books. If you’re looking for a cheap option that’ll help you get into the swing of things and you don’t need it to last a lifetime, go ahead and buy yourself an M4. For all other intents, just stick to something more reliable like the Crosman Nitro Venom.
