ok i new on here and im sure this is an old topic but oh well, i need some 2nd opinions. ive been dng a little researech on piston ar and there seems to be alot of them coming out now. i plan on kinda waiting around leting the competition fall into place and see which one is the best in price and quality. nothing against di guns but i just dont mind handling around the extra wieght. But, i know sme piston ar have a carrier tilt problem ( herd and seen pics the ruger sr 556 does this) but seen the hk 416 on fututre weapons which was awesome , any news on a civilian model?? also been hereing good things bout LWRC,POF,and the sig55x series. although the sig isnt really an ar or ive herd that anyway. Opinions??? thanks.
