I own an MR1.. looking for a place to buy aftermarket goodies for it. Live in Canada, so USPS is a GOOD thing, but I'll be damned if I haven't looked through the first five pages of this forum and not ONE SINGLE post regarding this gun... Anyone??? anyone? Hard to believe

I've got an MR1 .223. Looking for optics for it, but of course, doing my homework. Can I add an ACOG style magnifier in front of this unit as well? forgive me, I'm a bit new at this "aftermarket toys for guns thing" and I'm also Canadian, so the information is not so readily available for us regarding anything with the God forbidden word, "tactical" involved. I'm assuming that it will fit my rifle with the Pic rail? thanks for your time. Aaron.
