ICS MP5 metal upper no hopup screw points?
A question to everybody:
I recently purchased a replacement ICS MP5 metal upper from Hero's (yeah, I know, but weirdly enough they had it in stock and I received it within a week) to replace my old one where the front end mount fingers are broken. This NIB upper for some strange reason doesn't have the two screw-in mount points for the hopup unit/barrel.
Does anybody know when this change came into play and if this isn't a factory defect then where can I purchase the new version hopup unit if this is how it's now supposed to work? Also, the section that mates to the cocking tube part also now has a larger outer diameter. If anybody can provide some background info I'd appreciate it.
Thanks for any help.
