Question: will this be good for self defense ?
Document: Hunting, not fair to whatever it is your going after. Home defense, if it ever became neccessary to break out this gun you'll absolutely hit whatever your pointing near. If you can't tell I have had a lot of fun with this gun.
This gun is NO JOKE. To be honest, I think I'd rather be on the wrong end of a &#34;real gun&#34; than this baby. Whatever your purpose happens to be, target practice, home defense or hunting (if you can even say that with a straight face) this bad boy will get the job done and then some. I mean I was shocked at the capabilities of this &#34;MACHINE GUN&#34;.
This is the most affordable AND 50-state LEGAL submachine gun I've ever fired!Load the belt with .22 pellets, feed the belt into the gun, and with a full tank of CO2 or HPA, you're good to go!No loud noise, sounds much like a paintball gun, very controllable in full auto, and accurate, too. If you've ever wanted a machine gun, and couldn't justify the price, or can't own one in your state, this IS the opportunity you've been waiting for!
First let me start by saying this is no toy! A good solid spray will destroy a squirrel, very messy! Also there are a few things future buyers should know. Its 590 to 620 depending on fill and pellet weight, however, with HPA and some real modifications I'm getting 700 704 fps. The mods I've done range from building a twin magazine and other internal reconfiguring. Such as the bolt spring and the small aluminum hole the air comes out of and into the belt.
isnt that enough?
installed a Green dot haven't missed a  target yet.....full auto is just plain fun!!!!!!! Highly recommend one if you got the cash!!!! !
WE'VE USED SMG22 REGULARLY NOW 18 MONTHS. GUN OPERATES FLAWLESSLY. ONLY ISSUE HAS BEEN &#34;FILLED&#34; 20OZ TANKS CO2 OFTEN ARRIVED &#34;EMPTY&#34;. ALSO CHRONOGRAPH BEST 955 (WITH 4&#34; CUSTOM BARREL ADAPTER.)
Under CO2 it worked great, no issues at all, under HPA you get less variance in shots compared to the C02 and at 1200 PSI, a small bump in FPS. I still really recommend this air rile
This will also up the fps. At 12 rounds a second I see no need to go any higher. So for the record this thing is beastly and now I'm looking at this new GMG full auto pellet rifle. Its only getting 600fps too, we will see how long it takes before I get both of them doing 900fps and destroying cinder blocks Ha!!!
This thing is awesome ! i lay waste in front of my yard and wait for peasants to come eat it and lay it down like duke nukem ! i use my left arm to fire the weapon and lay the belt on my right hand spread about 12" away from the body like tah dow! and when peasants come and grabble at my feet i lay the hammer down on them!but yea this thing is bad A$$ and worth the money !
Answer: yes
