Description

New from Hellraiser, the HellBoy, provides satisfying repeating shots fueled by a single 12-gram CO2 cartridge. Based on one of the greatest weapons platforms ever created—the M4 Carbine—heat up the range with blistering semi-auto shots and unparalleled realism for a tactical experience like nothing on Earth!  

Each HellBoy features a full-metal construction throughout the barrel, receiver, and the 18rd  BB magazine. Load up a single 12-gram CO2 and start sending BBs downrange at speeds up to 495 fps.  Just like the real M4, the HellBoy gives you a lot of choices for your optics. Shoot straight out of the box with included open sights or remove the rear sights to expose the 5.5" Picatinny/Weaver Rail—ideal for a small scope or red-dot sight. Its adjustable rear stock can be set to your preferred pull length with the press of a button. Each HellBoy is field-strippable, and includes integrated sling swivels for easy carrying options.

If you want a truly thrilling backyard shooting experience, choose the HellBoy and incinerate your targets.

All metal upper and reciever is cool for realism. Nice weight to it, I read it's only like a pound shy of the real deal. Very, very quiet, the quietest airgun I own which is cool for backyard and even indoor shooting. Very accurate(read below however).

Be able to hold more BBs, given the fact you need to remove the mechanism from the metal sleeve that acts like a magazine, only 18 rounds and have to remove the entire thing to reload.

My front sight leaned a little to the left so essentially the rear sight is useless. You won't be able to change the grip on this so keep that in mind however, you can change the buttstock and handguard. This has no blowback or recoil, it's like shooting an electric airsoft which makes it very accurate, but also making it feel weaker than it actually is. If you want this for the realism, keep in mind it looks the part, but doesn't have any functional buttons, switches etc other than the selector. If you want an AR/M4 with functional parts, get a Crosman R1, Bushmaster etc, if you just want a cheaper carbine that looks good and is an accurate plinker, than this is a good buy. So being metal and a metal sleeve that acts like a magazine, this is good...just wish more of the switches, buttons..etc really worked. Still a good buy if you can get it for a good price.

From what I know, this is the best airgun replica of the M4. With a lot of metal parts, it is good to hold and shoot. The 495 fps and being field strippable add to the authenticity and fun factor. This is an airgun anyone would love to have in their collection.

Three things. First, and this is minor, the gun is not very accurate out of the box (but the rear sights are fulling adjustable for elevation and windage). Second, the magazine holding the 18 rounds of BBs and the CO2 could have a less cumbersome design and hold more rounds (at least 30). Third, and most important of all, this gun ought to have a full AUTO mode like the real M4.

This gun is fun. The gun comes in a box with 1 magazine, 1 hex wrench, and an instruction manual. I suggest at least one extra magazine.

Really nice authentic looking setup. I like the metal receivers. Nice weight. Breaks down the way it should. Externally, this beats the R1/DPMS series. I like the fact you can use real AR components on this. I wanted pink furniture for one to give my daughter, but it seems everything I look at under $100 is sold out. Nice solid removable carry handle/sight assembly. Good accuracy.

Wish it had full auto, but no big deal. I am painting the furniture pink on one for my daughter for her birthday. Design the bolt carrier group and charging handle assembly more like how the R1/DPMS is. I just bought both of them. Make the magazine internals more like the R1 series. I prefer the external Hellboy magazine cover though. The only thing I really hate is loading the magazine. The BBs keep getting stuck and falling out of the loading hole. There is no blowback on this one as well. I guess that is more CO2 to push BBs.

If you are set on full auto and more realistic internals and blowback get a Crosman. If you want more metal, less plastic, and such get this one. Or just buy one of each. One this one, basically everything to fire the BBs is in the magazine. The trigger assembly in the receiver pushes against a air valve lever in the magazine that releases the gas. That may be why the trigger pull is the way it is. If I had the time and money I would buy one more of each and see if I could make a Hellboy R1!
