The Sparrow catches a lot of flack these days with more well rounded designs out there, but honestly it has always done very well on rifles. No measured FRP on 16" and it came in just a hair quieter than the DA Mask in the old Suppressed Nation metering videos. This echos my observations as well, my Oculus 22 is an easy choice for pistols, but on rifles i can't distinguish it from my old Sparrow. I wouldn't buy one now over options like the Mask, Oculus or TBAC, but if you have one, it can live happily ever after on rifles without you giving up any performance to the new hotness options in that usage.
