The JP SCS (and knockoffs thereof) fall under the same reliability concerns for me as adjustable triggers/gbs/& bcgs. That's just me, though. I'd never tell anyone else it's wrong for them.
Adjustable gas blocks, only lower the port pressure the rifle barrel comes with. They require maintenance, to prevent carbon lock, unlike a standard gas block. Standard gas blocks can be just as un-reliable if the ammo doesn't match the port pressure the rifle was designed for. JP SCP's have been completely reliable in my rifles, with the benefit of smoother operation and the elimination of the buffer retainer detent and spring..
