I agree with what others wrote and I would add that most of us probably arent too keen on this "for pointing at $@!t" concept, it's kinda vague and gives an impression of carelessness.
When I let others see mine, i tell them it has the same rules as a firearm; be sure of your target, make sure there isnt anything around or behind your target that you dont intend to hit, dont aim at anyone or any animals (or at windows that people can be behind or reflective surfaces etc etc). However their ammo which is the speed of light and has no drop/ballistic coefficient, only divergence. Also, the dot on many is too bright to look at close up without safety glasses, and some can set "****" you point at ON FIRE. Basically a 10 min lecture
Yadda yadda yadda so you get the point, it's not exactly for "pointing at ****" per se, not to jump down your throat about it.
Y'all talking air guns without me?
I have considered that air arms SMG .22 but I dont want to go through pellets that fast and it isnt as powerful as I would like.
The lcs sk19 sold by airguns of arizona comes in .22 or .25 caliber, much like my huben k1. Pretty sure they reverse engineered a huben actually, they are so similar. One difference is that the lcs sk19 has a selector switch for semi AND full auto. The .22 can make 60 FPE at the muzzle and the .25 can make 70 FPE IIRC. Airguns of arizona told me that lcs is working on a .25 cal version that has a barrel made for slugs (like I like) and will be capable of 100 FPE at the muzzle. I'm selling my huben and buying one of those if they do that. Heck they shoulda reverse engineered it to shoot slugs like the huben k1 from the start, that's arguably the most unique feature of the huben, besides being hammerless and semi auto, but I digress.
If I had to get a full auto bb gun that used C02 (I prefer PCP airguns as I have a 4500 psi compressor and a large carbon fiber tank) I would probably go for the umarex legends MP 40 replica.
As for gasses used, I know that some people are shooting big bore airguns filled with helium and they are getting around 50% more muzzle energy with it. Something about it being a thinner gas, I'm not sure exactly. I wonder what my bushbuck could do with helium. On air it makes just over 600 FPE with a 470 grain slug. It's going 780ish FPS to do that, but I kinda like shooting 250 grain slugs out of it as they're cheaper and fly at like 960 FPS, so less energy but more expansion and a flatter trajectory
