I'm looking to get an SBR and put a can on it. My local shop advised me on the set-up with MPX SBR with a Rugged Obsidian 45 on it. He suggested the can b/c it can be used with so many calibers (45, 9mm, I've even heard it can go on rimfires) which would be a nice option. I wanted to see if anyone has this set-up and their opinions? Also, I'm not at all familiar with SIG Cans or handguns. Do any of you try to stay with a SIG can on a sig pistol or carbine? I'm brand new to this forum, but this has been a dream set up of mine for awhile. Closest thing to an MP5 I can think of, unless someone has a better example. If you have the MPX SBR suppressed with anything and are extremely impressed I'm all ears. Thanks for you help.
