Smooth shooter! - Adams Arms Standard Picatinny Block Piston Kit

I now have two of these Conversion Kit's installed. The first one was a 6.5 Grendel, and the last one just a few day's ago is a .223/5.56. I love the way they both function. I have another that I want to convert, but it's a side charge handle 7.62x39. They are cleaner operating with lower Maintenance. I have caught wind that the USA Military is also going to go piston. They'll love it!
