M4Super90

Thanks for the info. Now that you mention it, the receivers are totally different, so that would make sense.

Will the SBE barrels fit on an M2? This bbl. is for the original SBE, not SBE II. Thanks for any info, I couldn't find a definitive answer through search.

I'll buy it, but I'm in Canada...........unless you ship north. How much?

I see, thanks It does work for that purpose though

New guy here, first post. I bought an M4 a couple of weeks ago, it has the collapsible stock. Before I get berated for legalities, I'm in Canada. I've done some searches on this site, but can't find an answer to this one: The stock on my M4 has 4 positions, which all lock in place. 1.fully collapsed 2.mid position 3. locks butt pad at 45' angle 4. fully extended I can't find any info on position 3. One fellow in another forum said it is for looking around door frames, which sounds like it makes sense. True? The manual says 2 position stock, and I know that's wrong. Thanks for any info. Awesome gun,BTW.
