That picture is from the brownells website i believe. .154"
Any decent manufacturer is ok with me. Personally i think its way too much..but then again i tend to be a cheapass when it comes to some things...Oh did i mention i went to a funshow yesterday and i managed to piss of 3-4 people because they were trying to tell me 30rnd AR mags are getting rare and thats why used GI mags were still $20 each and 30rnd AK mags were $15 each
My ass!!I dont know why i go to this specific show every year its always lame and way overpriced, and yet table holders are bitching that they cant move any product and have to haul everything back out of the show
