It looks like a real gun and is powerful

Make it a Bit bigger

By DaveApril 5, 2020

I made a simple box of ABS plastic card to slip over the Mag it has a funnel shape inside and all you have to do is put the follower on lock back and then fill the box with bb,s and rock it back and forwards gently and the mag fills in secionds

All metal receiver and barrel accuracy is quite good

Personally I really liked this airgun. Very accurate and a blast to shoot. Loading the clip is a bit of a pain, but worth the fun. However mine just quit working out of the blue. Airgun Depot made good and sent me a replacement. So we'll see

Very accurate. Blast to shoot.

Tad hard to load. Quit shooting and had to have it replaced in a short time of use

I’ve set my hellboy up with a quadrail front hand gaurd,tac light, scope, buttstock pad,cheek pad, and a comfort grip. Great gun for plinking and pest control. I recommend getting a co2 gasket to put around the co2 piercing needle as it limits the co2 loss during cartridge exchanges. Other then that minor detail I love the hellboy and all its ability to MOD.

Fully modifiable, powerful, accurate, and realistic!

Needs a gasket to help prevent co2 loss during cartridge install.

I have grand kids that are going to learn how to shoot. I want them to be familiar with the "Black Gun" right up front. It's important to pass on our skills and heritage. I have the good fortune to have a place to shoot but it's really handy to just step out in the back yard for a little inexpensive fun. It's great for dry fire. I would recommend this rifle to friends.

Reasonable price realistic function all metal reasonably accurate

co2 leakage when installing cartridge. elevation on rear sight will creep when adjusting aperture.

The first one I received was a dud and as the same day AGD received it back they shipped me a good one. Craig handled my RMA I think. This gun not getting into exact measurements is a great replica of what has been the AR platform issued across most of the U.S. Service . It has the look and fell. You can separate the upper and lower by tapping out the pin. The charging handle is just for looks. I do recommend opening the Dust cover when firing for in the rare incident of a BB jam. They are easier to un-jam when there is a place the BB's to go. The Sling Swivels hooks are cool. I also found that it will attach an M7 Bayonet. My M9 will not fit over the muzzle break. The gun bayonet sattachment doesn't match the exact M4 attachment I am familiar with What the gun consists of is a double action trigger striker, the Magazine where everything happens and a nice long steel barrel for a BB gun Now for shooting I don't have an chronograph so I don't know the real speed. Using mine on Days in the Low 80's F It is piercing steel coffee cans and Bush Baked bean cans at 10 – 20 yards. I have most always get 8 full mags out of a co2 cartridge and it runs out of gas. So that is 144 shots. Although you have to single drop the rounds in it is friendlier that other guns built to single drop the BB's only into . If you have all your fingers and decent dexterity that is nothing to write home about.

accurate hard-hitting efficient on co2 good for cheap practice and you don't need to use “ears� with this in your back yard

It would be cooler in a larger magazine capacity once I am really in the zone knocking targets away at targets its time to reload. Again I can refill the mag in approximatly minute. No big deal.

So I bought this just for a little project I was doing to see if I could use it as a training rifle... Turns out it was a great purchase. I added a real m4 quad-rail, it was kind of difficult to get on, but it fits and is solid, so I went with a SOPMOD Block 1 setup. I added a rugged mock combat ACOG, AN/PEQ-15, Bipod, crane stock, sling, 1-point stock mount ring, foregrip, and mock suppressor. It is about a pound lighter than the real SOPMOD kit, (there's no buffer or spring so that's why its lighter), but it is freaking amazing and solid to use as a training rifle. Minus the lack of a functioning "bolt carrier" and bolt release. It hit a way higher expectation for me than what I initially expected. Love it so far.

Like I said, its about a pound or more lighter than the real deal with my SOPMOD setup, and it also is pretty light out of the box. -No mock bolt functions. -The pistol grip is NOT compatable with any real AR pistol grips, only the one it comes with.

This BB gun is really fun , very accurate and decent range.

Accurate , Real Feel

Safety super weak , mine broke withing 3 days of use a small spring popped out , I fixed it my self with a rubber washer so is not easily switched on and off .

By HarryUSAJune 27, 2018

The gun is good, but the magazine needs some improvement, either the prob that pierce the CO2 cap needs to be 1/32 shorter or the shield should be 1/32 thicker, then the gun may goes up to 90 shots each fill. Good power out to 20yards, for money is worth. I try most of the steel BB, Smart BB and Dust Devil, it looks like the Smart BB works best. No other commend.

Light weight.

Improve the magazine, the prob is too long, some gas goes before tighten the cap. Either the shield is 1/32 in thicker or the prob is 1/32 in shorter, this can allow the cap tighten faster.

I just received my HellBoy M-4 from AGD. To start with I Chrono'd mine using both the 5.1 gr Daisy premium BB�s and the Dust Devils 4.35 gr. I had a high of 402 FPS and a low of 327 FPS, it averaged around 357FPS, which was totally unacceptable. The accuracy was absolutely horrific. At 30 feet you could maybe hit 3 out of 10 soda cans. The BB�s looked like curve balls coming out of the end of the barrel. One of the worse performances I have ever seen out of a smooth bore BB rifle/pistol. This gun has a 14 ½� barrel, if the gun is producing the proper Co2 release it should be getting 500-600 FPS. I have a Crosman Comrade AK CO2 Semi-Automatic Rifle that averages around 600 FPS, It has a similar length barrel but the accuracy and the power is beyond comparison.I truly believe this HB rifle is defective.

Dealing with AGD is always a pleasure. I received my HB M4 last night and tested it out today. I apparently received a defective model and AGD (Craig) immediately responded to my email and sent me a shipping label. I already shipped it off for an exchange. After reading one other review, (PA), that individual's rifle had much better performance which confirmed I received a defective model. I am hoping that is case and if so I will be happy to amend portions of this review.

I want to mention the loading of the magazine is a real PITA. Removing the cover is easy, but inserting the BBs is a chore in that you have to insert one at a time. The Co2 loading is really bad as well. You have to get the Co2 very snug, then you have to tighten the bolt very fast to make a seal, however, it will still leak Co2 in the process. I used a T-handle Allen wrench to speed up the process. The gun looks great but I do question the way the Co2 valve/trigger lines up with the barrel. If the BB opening in the magazine does not line up perfectly with the barrel it could cause major resistance with the BB as it transfers into the barrel, which causes an unconventional spin on the BB as well as drastically slowing down the FPS. This could be a design flaw, we will soon find out when I receive my replacement model. If the accuracy and FPS could perform as advertised, I will purchase an additional magazine or two.
