Tactical Pith Helmet Posted October 27, 2021 Posted October 27, 2021 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.
Iceni Posted October 27, 2021 Posted October 27, 2021 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.
Skara Posted October 28, 2021 Posted October 28, 2021 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.
ak2m4 Posted October 28, 2021 Posted October 28, 2021 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.
Skara Posted October 28, 2021 Posted October 28, 2021 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

Tactical Pith Helmet Posted October 28, 2021 Author Posted October 28, 2021 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.
