that's right, a real one will cost a bunch more, as there class 3 weapons
have shot both and owned a few of each over the yrs
there simple things that work well, with decent mags and ammo!
there much more enjoyable to shoot with a suppressor on them which you can hold onto

in semi form? there nothing special , and doubt either one would be more accurate than the other short barrels here?
as for what one will work better/be more reliable?
again, pick of the liter here, as well as you need good mags and then decent power ammo to cycle well!
never really had any issue's with either one being all too picky, but mags were at times a issue
sold(had gun shop) both semi and full auto's of these!
and to me neither is worth the money to buy!
