I've put this piston system in all of my AR platform rifles. Even in the AR 7.62x39 just dial in the best gas flow watch the ejecting brass look for a 3:30 to 4 o'clock brass flight and if you use a suppressor later you can adjust the gas flow accordingly. I use this system in my AR-15's (5.56x45mm) 55gr, 62gr, 68gr, and 77gr. Also my AR-7.62x39mm & .224 Valkyrie 80gr, 88gr, and 95gr... I've got a message from Superlative Arms informing me that they will be coming out with a AR-10 version or LR-308. They said it will be announced on Instagram at the end of a year or the next physical year??? When ever that is??? This piston system is a one piece bolt system it a work of art it's beautiful and a cleaner way to shoot. Remember to read the instructions remove the 3 gas rings!!!

I've got the Superlative Arms piston system in all of my AR platform rifles.I even put it in my AR-15 chambered in 7.62x39mm (123gr),(150gr).Also in a .224 Valkyrie (95gr)(89gr)(80gr)It work's flawless in all my AR-15 platforms In my 5.56x45mm I shoot (77gr),(68gr),(62gr), and (55gr) flawless shooting. It keeps my rifles cleaner and if and when I get suppressors it's easily adjustable to do so. It's adjustable for ejection timing it can be a softer or a harder kick. If you get the adjustable gas block only is the same function but a dirty gun is expected. I have a 7.62x39mm side charge rifle so I used a adjustable gas block "didn't feel like drilling and tapping the bolt carrier & voiding any warranty" I'm hoping Superlative Arms piston system will be made in LR-308 size??? I will be shooting .308 (7.62x51mm) in (170gr) to (200gr +) depending on the distances???
