I have decided it's time to add a piston AR to my collection. I pretty much just want to try something different; I have four DI AR's now, so i figured I'd give it a go. I have no problems with DI, I love what I have, not looking for something better or more amazing or miraculous... You get the picture. I don't want this to become a piston vs. DI debate. That all being said, I picked these two because they seem to represent the middle of the road in terms of piston gun prices. The M6-SL is one of LWRC's entry line, and the PWS MK114 is pretty much in the same price range. I appreciate both company's reputation in terms of quality and customer sevice. I've chosen both over your typical Stag, Sig, Ruger, etc options, but between the two I'm not sure which one I like more. I have never handled either, so that might make my decision easier. They both fall in my price range, and I'd like to not reconsider any options the next price range up if possible. I think I could get what I'm looking for in either of these two without having to spend more. What are your opinions? Recommendations? Anyone own one of these? Any complaints about either?
