The same concept, manufacturing process, tolerance and quality, but with different dimensions. Privides better range, more accuracy & more flat trajectory.
Width fit to for most AEG chambers, however the variety of manufacturers, and their tolerance make some chambers too tight, you may need polish or sanding on the sides.
It also provides pressure more efficient than usual nubs, may need to modify you hop arm depending on which bb and velocity you shoot at.
Also works in GBBR rifles with similar nub concept like GHK M4.
