I have 3-516's.  I think there are awesome. Soft shooting when suppressed and just generally a solid rifle.   Does anyone have both?  I like to hear some comparisons. Thank very much for any input

I have to agree about the 516.  I have several of them myself.  All have been 100% reliable, accurate and reasonable recoil for a piston rifle.  They are built like an Abrams tank.  Very heavy duty and solid.  Weight is the only drawback, imho.  No experience with shooting the LWRC although I have friends that have them.  I have handled them and they seem to be of good quality as well.  My biggest grip with them is that I simply can't stand that fluted barrel they use!
