I am considering trying out a piston system AR type rifle for the first time and would like some input as to which company produces a better piston system. I would guess they are similar designs, but I'm sure there are some differences.

I already own an LMT SBR and it is an incredible weapon. I have held one of the LWRC piston rifles, but not fired it or taken it apart to look at how the system is put together.

Thanks in advance.
