If you do get the FV-SR, I recommend the SWR Spectre II can. The 22 LR is so inherently dirty that the stainless steel baffles and a unique sealed baffle snap system make cleaning a breeze. Search for it on YouTube and watch the comparisons and cleaning vids. PLUS it can handle all of the compatible calibers and it does well on both both rifles and pistols. Note: not all cans handle both equally on suppression. I will be dead before this unit wears out because it is so well constructed. I got a family trust going on my NFA application so my sons can inherit it without paying the stamp tax. PS processing was 5.5 months on mine but my dealer is talking 3 months transfer to him and 7 months processing due to the country going broke and needing to lay off people who process this paperwork. On a good note mine is Hollywood quiet shooting subsonic rounds!
