It really depends on your gas system length and gas port diameter, but an AR15 rifle buffer and spring are one of the better options when looking at reliability across a wide range of rifle and carbine configurations.
I've seen the rifle buffer/spring combo in a rifle extension tube work reliably on:
* 24" RLGS
* 20" RLGS
* 18" MLGS with too large of port, but an adjustable gas block choked almost all the way closed
