Years ago i borrowed an mp5 with a rotary hop instead of the TM style hop. I have never been able to find out what make it was and never been able to find a similar set up. Anyone know what make has a rotary hop?

 
ICS perhaps?

Just a guess. Every MP5 Ive ever seen or used (and its been a lot, I love them an unhealthy amount) has had the TM style sliding stick hop in the ejection port or a lever in the foregrip. Ive had TM, CA, Cyma, JG and some others, only one Ive not had is ICS and I know theyre a sucker for proprietary parts.

Nope ICS doesn't use a rotary hop in the MP5 range. It will probably be a unit modified to fit.

That's a damn shame, as the slidey hop in my MP5K goes off quicker than a politician's promise.  I've whipped a cable tie around the slide arm to put more tension on it, but it generally needs a lunchtime adjustment.

This is what puts me of AKs as well. Didn't actually know MP5s had one puts me off them even more!

MPX on the other hand.....

 
I think my Classic Army B&T MP5A2 has the rotary hop

(I'll post pics when I'm home later)

Its an old variant and not sure of the actual model because I bought it second hand.

I think its called the BT5A2

Its one of my better shooting AEG's too :D

Got an old TM Mp5k somewhere will have look when I get chance to see what hops can be modded to fit.

Never really bothered with the B&T mp5s but the few I have opened have all been normal affair. Will try and track one of that model down for a look.

Scratch that...  :unsure:

I was wrong, it doesn't have a rotary.

Sorry

 
Might have been an UMP.

On mine the fix that worked is something I read here, but don't remember from who. It's for the one that has a tilting arm next to the barrel, not the one where you have to remove front end and slide the arm forward or back.

A little piece of a bonding tape between the arm and the outer barrel does the trick.
