HFC full metal full auto beretta non working for spare/repairs

No magazines included

Lower half seem to work ok with the other slide on the other beretta i have listed so

i assume the problem is a faulty part in the slide half.

£35 including postage and pp fees or £20 each for a complete upper or lower half

or i would sell the two berettas i have listed with two mags in a hard pistol case

for £80 including postage and paypal fees
