I am looking to get a can (soon) for a 14.5" SBR'd AR15. Now there is almost too much information out there-- all telling me which can is best (of course it's always the one that they make ). I would greatly appreciate some help from local can owners. Especially info as to who go to to purchase my new can. So far I like the AAC M4-2000 and the Gem-Tec Halo, but that is just from reading their published info. Another other help would be great. Thanks all.
