I don't blame the guys on youtube or anyone who may or may not have shouldered one as much. But all these manufactures submitting "Is this ok" "how 'bout this, is this ok" and people who wrote the ATF for any further clarification are idiots. I mean damn, the friggin' box comes with a letter from the ATF basically saying shouldering it doesn't change the classification of it!! Y'all don't understand English?!?! You ever heard the saying "you could #$%& up a wet dream?" It was invented long ago by a very wise man after witnessing such dumbassedry as that.... Be that as it may, I still kept my braced AR "pistol." Feel sorry for all those guys who felt they didn't want to run any risk and took a big loss selling their braced pistols at 1/2 the price they bought 'em for though. Sorry to digress off the topic - Cool Shotgun. I posted before you can buy that receiver and everything to build that for probably $450. There's not really much to a 500 so by "build it" I basically mean drop the parts in and screw on the barrel
