I fired the "pistol" version of it last Tuesday, needless to say a "unique" experience.
1) Hard to acquire a solid firing position.
Can't be "shouldered" like an M-16 nor can
it be fired like a conventional pistol.
2) Lacking a "quality" sights. Peep sight was
adequate, but for the price paid they could be better.
3) Muzzle blast was incredible. Much more
than I've ever seen on a rifle caliber pistol.
All in all, a fun toy to have but if purchasing to fill a "need" there are other,
better suited, options available.
