I don't know much about piston ARs from personal experience, but after you're review I think I fully understand not only how the piston system operates, but also why there are advantages to a piston system in regards to carbon build-up. Looks like a nice rifle! Great review!

Thanks.

I’m glad to hear you enjoyed the review, and that I was able to shed some light on the differences between the piston driven AR, and the direct gas impingement AR.
