I like tinkering with piston systems.
According to the measurements, this should be compatible with more handguards than other offerings.
It seems it would fit with my LaRue rail, and it might even fit under many rails like a low pro gas block.
As an AR tinkerer, I think the saying goes "SHUT UP AND TAKE MY MONEY!"
PS: My CMMG kit I bought years back is still working great. Other than the too much extra weight it added, my AR ran smoother, softer, and functioned flawlessly with it.
Mind you, it needed tweeking over stock.
