I have an AirSoft M4 which looks very close to my Bushmaster M4. It's an amazing in the similarity (except for that red flash suppressor). I have a couple of .177 caliber air rifles that shoot BBs or pellets. I guess those could be considered as weapons.
In the firearm category, I have rifles and pistols/revolvers of various calibers, shotguns, and muzzleloaders. That's usually all that's considered in "firepower", but if you include archery, I have two compound bows.
And then there's the edged weapons category, well, I have more of them than I can carry.
