So I have to thank you Hoss for pointing me in the direction of that AR upper, because the seller turned out to be Wade Rorich from Bushido Tactical (his Arfcom handle is SSA, and a "Team Member" whatever that means) Anyways I got the upper so I could properly mount my Comp M3 with a rear BUIS to get it ready for some courses that I was looking into. Well, BAM Wade hits me up in his last email with a "by the way...did you know that I will be teaching a few courses in the Sarasota area...are you interested?" I was just like......after reading the email. SO it looks like I will be heading to a Defensive Rifle / Carbine Readiness Course in December (13th - 14th) and then a Defensive Handgun Readiness Course in January ( 24th - 25th) So SEE, who says that just buying "useless" gadgets for your rifle is a waste of time. I purchased a flattop, AND got into some good courses at the same time. lol. I like the upper too: So if there are any Tampa Bay area or SRQ folk who want to join in on the fun, let ye be known that those are the dates of said courses. CLIFFS: I unknowingly purchased an upper from an instructor from Bushido Tactical, who then invited me to come take courses in my area, which I meant to do anyways. Crazy coinkidink me think.
