O Dont worry, the spending has already started. I have had 3 different stocks, 2 different pistol grips, a new forarm freeflot tube...(but not before i bought the aftermarket plastic handgards by first samco((((crap))))). i also bought a flattop A3 upper reciver. rear flip up sights and now the front flip-ups. Most of this is before i found this lovely web site. This is the last place i needed to stumble across. I would be better off driving down the road and throwing money out the window.(I also am wanting to buy an eotech or aimpoint optic.) And all of this is just in the last year or so since my first AR purchase. AND yes, with all of the parts i have laying around i have thought about buying a stripped lower rec.(until i found out you had to register the damn thing... even if it is stripped...hey wishful thinking) And then i bought a blackhawk vest from a friend. the vest had a pistol holster so i had to go out and buy a Kimber custom II to put in it. (it just wouldnt be right without it!)Just in the last week i have bought the Kimber and a benelli nova tactical shotgun. And i am looking for the barrel which brings me to my question on which to buy. Also Eotech or aimpoint????? I like the eotech 512 i think. (the one that takes the double A's) this is probably like 3 new threads, sorry. but also thanks for all the help.-derek
