I've written about, and photographed my Air Venturi HellBoy M4 Tactical .177cal. Co2 BB Rifle a number of times.
It is one of my favorite AirGuns, although, I wish I could upgrade it for .22 caliber lead roundball, instead of .177cal/4.5mm steel BB.
Presently, my HellBoy M4 has an aluminum alloy quad-rail handguard with my angled forgrip attached, and the stock has a US Army rubber buttstock recoil pad.
Any one of my gun lights work with this AirGun, and are much easier to use now that the quad rail is on the gun.
What is the handguard lenght?? 6'7 inches?
ReplyDeleteI'm thinking about buying a hellboy m4 and your mods serve as inspiration.
Kind regards from Spain.
Hi David, yes, you are correct, 6.7" is the handguard length.
DeleteThe aluminum quad rail that I installed is available from many different Chinese eBay sellers for around $20 USD, and it is excellent build quality.
Thankyou for your comment, I am glad that my blog has been helpful!
Can I assume a standard as found on amazon 7 inch handguard won't fit
