Just picked up my M-455 SAS w/Pics
I just picked one up last week. I can tell you it's made very well, solid, good finish. I've only had a chance to put a limited number of rounds through it and no time to see how it affects POI, I haven't got my scope zero'd yet! I,m very happy with it so far and don't think my opinion will do anything but get better about it. From all I can tell it's a great value compared to a lot of other cans available and I like the shorter length. I'm not convinced adding two more inches and only getting a few more DB in sound reduction is worth it. I'll follow up when I get some additional time with it. So far, I'd highly recommend one, pretty hard to beat for the $$.
