Looks pretty cool, would like even cooler if it had came with the front sights

The rear sights are super cheap plastic. Kinda like a toy kids toy and seems to have a lot of wobble when your pumping it

Mine arrived without the front sights, not sure why they didn’t have it already on there but it wasn’t. I have to send it back and wait again for a replacement. Shipping time was like 11 days the first time. I think the FPS may b exaggerated too

This review is for the M4-177 Kit. That's important for reasons I will mention later in this review. Unlike other replica airguns I've reviewed on this website, I have never shot a real M4 carbine. Having said that, I REALLY love this gun! It is essentially the tried and true 760 Pumpmaster but with a cool M4 outer shell. It has a rifled barrel so I don't recommend shooting BBs. Stick with Crosman pellets. The indexing pellet clip may seem awkward at first, but once you get the hang of it you'll see why Crosman has been using it for decades! Accuracy and reliability are outstanding, just like the 760. It's all plastic on the outside but it looks great. Real M4s are pretty much all plastic on the outside too, so it looks very authentic to me. My wife loves it and hit quarter sized groups on her first try! The basic version is currently $59. The Kit version with the carry handle, extra clips and other accessories is $69. I bought both with the wife's approval. Need I say more?

Nothing really. The manual could be a little better. I'm still trying to figure out what the little thumb switch on the underside of the buttstock (just behind the receiver) is for. I think it has to do with removing the buttstock, but I'm not sure. If anybody knows, please let me know.

The M4-177 is available in different packages. The Kit version comes with a carry handle which is why I bought it. It also comes with extra clips but no tool to adjust the sights. Why? Because the front sight on the Kit version is not adjustable, and the rear sight on the carry handle doesn't need a tool. The basic version has adjustable front and rear sights, both which require the tool, which is included in that version. Bottom line: The M4-177 is a 760 Pumpmaster with a 21st Century tactical face lift. It's super accurate, super reliable, and tons of fun! Buy extra clips and a lot of Crosman Match Grade wadcutters! One thing about all Crosman airguns: They really prefer Crosman ammo, lubes, etc... I don't use Umarex or Daisy products in a Crosman and vice-versa. The underside Picatinny rails are useless but the topside rails are great. I've tricked out my M4-177 out with a reflex sight on the receiver and a laser on the barrel. A Very fun gun and very highly recommended!!

@William: I found the 'clip' to be more of a hassle than an asset, but to each his own. ;-) FYI: Just in case you didn't already know, you can get extra 'clips' on ebay for a song, compared to what the genuine articles cost. I disliked the time it took to reload the clip every five shots (I shoot quite a bit), so I ordered sixteen, which keeps me shooting instead of re-filling clips. I suspect they've been 3D printed, as they are very affordable, but they still work perfectly after almost a year of use. I hope the info helps you out. Enjoy your replica!

DAAAAMN BUDDY YOU GOT THIS AIR RIFLE DOWN PACK TO THE T-BONE NICE I SEE YOU ENJOYING IT YOU MAY MEAN WANT TO PURCHASE ONE SO I WILL BE RIGHT NOW THANKS FOR THE BREAKDOWN

William Aug 16, 2020

One more thing: I finally figured out what the little thumb switch on the underside of the buttstock is for. Pull it back and slide the buttstock up which allows you to remove it. A cool feature which is mentioned nowhere in the manual. Do this with the rifle on your lap or gravity will take over and you'll end up dropping the gun. I learned that lesson the hard way! The gun is fine, but the fewer times you drop any airgun, the better!

After well over 1000 rounds, here’s my follow-up review of the Crosman M4-177 It’s excellent! Now, for a few observations: Don’t bother giving it 10 pumps. It’s too much work, adds little power, and only adds unnecessary wear and tear to the pump mechanism. My chronograph results are as follows: 10 pumps = 575 FPS. 5 pumps = 465 – 475 FPS. 3 pumps = 375 – 400 FPS. 2 pumps = 275 – 300 FPS. I used both Crosman Match Grade 7.9 gr. wadcutters and RWS Meisterkugeln 7.0 gr. Wadcutters. There was no noticeable difference between the Crosman and RWS pellets. The same is true for accuracy. Free standing at 20 feet I am easily able to shoot penny-sized groups with both the Crosman and RWS wadcutters. Long story short: If you’re shooting indoors at 15 to 20 ft., give it 2 pumps. If you’re shooting outdoors at 20 to 30 ft., give it 3 pumps. If you want to a little more horsepower, give it 5 pumps. Don’t give it 10 pumps. It isn’t necessary!

AR15 style body, good for a youth trainer. Also enough power and accuracy to take small pests.

The front sight rail is set lower than the upper reciever rail. So buying after market sights that would match up is slim to none, so you will be stuck with the factory sights.

Factory sights came to me molded in a way that they were BOTH canted slightly to the right. Although it does shoot straight because of the rear windage adjustment, it just bothers me that I couldn't use a different set of cheap flip up irons due to the difference between the front and rear rails. Furthermore, a simple bipod set will cut accuracy of weapon in a third, going from 1" at 15 yards to 3" at the same.

Accuracy, realism, and the 5 round magazine provides for hours of fun plinking.

Nothing.

This airgun is great for maintaining target shooting proficiency.

Pretty close to looking like an AR-15. Price point is a definite plus.

A proper carry handle with the hole for mounting rail adapters would have been nice.

The versatility of having a detachable carry handle seems like a great idea. However the handle as supplied forces one to remove it to use a rail mounted optic. Then remove the optic to use the handle with the open sights. A hole in the carry handle would allow the use of any one of rail adapters to be used to then mount an optic. This would give a more accurate appearance for the replica collector.
