SHS Rotary Hop

[Tactical Pith Helmet]

Are these worth getting?  I resent being asked £15 plus postage for a ZCI unit until AK2M4 gets some stock in.  Then again I'd not begrudge the extra if the SHS unit is crap.  

 

I particularly like the way the ZCI doesn't shift when adjusted.

SHS used to be decent but I have a distinct memory of them moulding the nub into the arm with a design revision, Effectively making the unit worthless. @ak2m4 Should know more than me.

I can confirm they use an integrated type B tensioner.

Definitely not an issue if you're not using a R-Hop or any other concave patched rubber (Maple Leaf and others of similar shape). In theory it works exceptionally well with PDI W-Hold rubbers.

 

Adjustment is SUPER stiff but once tuned, they stay there no matter what.

 

Before buying three Maxx chambers I had one of those (black) in my PDW and it worked flawlessly with a prommy purple.

as skara said it's got the molded nub on the arm now so not hugely beneficial for flat contact-patch buckings.  last few days I've been testing my new nubs and bucking with lots of different combinations of gearbox shells, chambers, nozzles - it really is a nightmare of a minefield.  If you do a lot of builds then it's really worth keeping a few different brands to hand.

It is still a good chamber!

You can also swap hop arms with similar shape units, I, for example, swapped the arm with a madbull one once.

Not the same dimensions but it fit nice and allowed me to use concave tensioners

But if I had (say) a ZCI rotary hop, why wouldn't I just use the whole ZCI rotary hop?

Yes, but what if you're replacing a cracked unit? You can still use the "universal" arm

Cheers for all the info everyone.  I may give one a whirl and see how it goes.  Definitely a good idea to get a few in stock I think.
