Hey guys I recently ended up with two new black rifles, a Sig 556 Swat and a LMT CQB Piston Defender. My main question is concerning the longevity of each weapons gas system, which one is stronger and whatnot. I am quite new to the piston driven rifle scene so I wanted to enlist the help of those with more experiance.

From what I have found out, the LMT is one of the finer Piston Driven AR platforms available but how does it compare to the strength and reliability of the SIG?

Any info on either type would be helpful, as the LMT seems to be so limited in production that it has proven to be very difficult to find much info about it at all.

So guess my question is, which of these rifles would you pick and why?

Thanks guys
