Must have for suppressed sbr
This buffer spring is an absolute must if you are running a suppressed SBR. I bought this looking for a way to manage the excessive recoil I was experiencing when suppressing my 11.5 with the hotter M193 loads and 77gr loads. I was a little hesitant at first, because I did not want the lose the ability to shoot softer loads if it was all I could get my hands on. I dropped it in my rifle with an H2 buffer and it ran as smooth as anything I've ever shot. I tested it both unsuppressed and suppressed with very soft shooting 55gr .223 loads, Hornady Frontier M193, and IMI 77gr Razorcore. Every round cycled perfectly and I achieved bolt hold open on every last round test I put it through. I cant say enough about this spring in conjunction with an H2 buffer, I highly recommend it.
