Type: BB Rifle.
Manufacturer: Air Venturi.
Materials: Metal & plastic.
Weight: 5.2 pounds (2.4 kilograms).
Barrel: 14.5 inches, smooth bore.
Propulsion: 12 gram CO2 single cartridge.
Action: Non-Blowback - double action only.
Ammunition Type: 4.5mm steel BB's.
Ammunition Capacity: 18 rounds.
Trigger Pull: The trigger pull on the Air Venturi HellBoy M4 CO2 BB Rifle is a double action only trigger since there is no blowback action to set the trigger in single action mode. So it will be a bit heavier than a true single action trigger. That said the trigger is not bad at all and can be activated very quickly for tons of fast action shooting or at least until your 18 rounds are all gone :) I would say the trigger pull is between light and medium with a medium pull length and not that much take-up at the beginning.
Accuracy: So far I have only played around with the Air Venturi HellBoy M4 CO2 BB Rifle shooting at clay pigeons from various distances and it was surprisingly accurate for me off hand shooting like this. I could easily hit a clay pigeon from about 50 feet away with most shots. Watch my "Having Fun with the Air Venturi HellBoy M4 CO2 BB Rifle" video if you want to see how it did. In terms of velocity, I have seen other reviews that show it getting pretty close the 495 fps claimed so until I do my actual Field Test Shooting Video we will have to go on this info.
Build Quality: The Air Venturi HellBoy M4 CO2 BB Rifle is made in China, some people will not like that but I found it to be very well built in general, fit and finish are as good if not better than any Taiwanese airgun I have reviewed so quality control in the factory must be good. You are going to find metal parts where you would expect them to be on a real M4 (AR) like the receiver, barrel, buffer tube, magazine, carry handle, forward assist, charging handle, sling mounts, safety and magazine release. Plastic parts are going to be the rear stock, hand guard, and pistol grip.
Realism: The Air Venturi HellBoy M4 CO2 BB Rifle is a 1 to 1 replica of the M4 or AR platform and even has some interchangeable parts with real AR or M4 like the hand guard and rear stock. You can even take this gun down into the two halves, upper and lower which makes for barrel cleaning or BB jam removal pretty easy. Even though there is no blowback action or internal bolt, you can pull the charging handle back which opens the dust cover just like the real deal. Other working moving parts are the magazine release, selector switch, forward assist and adjustable rear stock.
- Great to have another full size Rifle available to purchase in a BB gun version.
- Metal where it is expected and good overall weight. (Metal receiver, barrel, magazine)
- Can be field stripped, carry handle is removable.
- Can swap out hand guard and rear stock with real steel AR parts.
- Full size drop out metal magazine that holds the BBs and CO2.
- Great looking replica of the real steel M4 AR, operation and weight.
- Variety of sling mount hook in points for varies styles of slings.
- Fully adjustable rear sight with duel apertures.
- Working, dust cover, forward assist, magazine release, selector switch.
- Price point is reasonable for this type of full size mostly metal BB rifle.
- Semi auto and double action only trigger only.
- Magazine only holds 18 rounds and a single CO2.
- No blowback operation.
I think the Air Venturi HellBoy M4 CO2 BB Rifle is a super addition to the replica rifle lineup. I know we all wish it had blowback operation and shot in full auto mode too but there are trade-offs here and you can still have boat loads of fun shooting the Air Venturi HellBoy M4 CO2 BB Rifle even in semi auto only mode. The fact that it does not have blowback allows for some generous fps velocity and more shots per CO2. It looks really great, feels really great and shoots really great all in a mostly metal build which is what everyone has been asking for and at a reasonable price. I think the Air Venturi HellBoy M4 CO2 BB Rifle is a total winner and recommend it 100%. You will not be disappointed!
