The superlative arms piston kit is the best thing you can add to an AR platform, especially if running suppressed. It will get rid of nearly all blowback an is much much cleaner. I have 2 of these kits, one on my carbine and one on my target rifle. I will not build another AR without one.
Unfortunately they will not work on a 300 blackout yet. I called superlative arms and spoke with a guy named Tony, he said that he is coming out with a light weight kit for the blackout sometime spring of 2017. I also have a SBR blackout that I shoot suppressed, I tried everything I knew to try and could not get the thing to function reliably. The way these kits work I will definitely buy one for my blackout when they are available.
Y'all are correct on the handguards, as long as your handguard has a top rail ridge it will fit. I run the stinger supremacy handguards, they are a smaller diameter(small enough my 1 1/2 suppressor will not fit inside) but has a top rail and both of my clear.
If you are thinking about getting one of these kits, don't hesitate, they work really well. But hold off if you are going to try it on a 300 blackout, wait till the dedicated kit is available.
