I remember those POJs way back then, Never very reliable and the plastic frames were notorious for cracking, I Had the full size open bolt for a while and form twoed it The SMG had a Very fast cycle rate, 900_ RPM+. Definitely Not a go to war gun. The Carl Gustaf m45, Swedish K mags look close. Later from Texas.
I used to have a tec DC9, but it jammed so much no matter the magazine or ammo type I tried. And I tried them all. The only cool thing about it is the fact that it looks cool, looks like a sprayer. But the mechanics sucked. Eventually I traded it to a friend for a.50 BMG upper
@psp1921tsmg mine didn't so I traded it along with few dollars to a friend who gave me his Ferret arms 50BMG upper whitch sits on an AR lower, shoots great.
