Actually, you CAN aim this weapon very well.
Attach a m-16 sling or shoulder strap to the rear sling lug in a "single" connection mode, leaving the front sling ring off. So one big loop or both strap ends connected to the same sling lug ring.
When you raise the weapon, you extend it out until the sling is tight and you are PUSHing forward to create stability.
At this point, you can raise it to eye level just like it was a rifle (but with not stock) and aim it
OR
Fire the first couple of rounds and "walk" it on to the target.
I find that you can be pretty accurate (not percise) with it this way.
Keep in mind, it is a very short barrel and I would only expect decent results at and under 50 yards.
Very fun to shoot ANYWAY you decide to shoot it. I love mine. More than the HK SP89 clone I have.
