I like how you screamed "WHAT?!" like Lil' Jon. YEEEEEAH!
Anyways, if you think your Magpul PTS products are built BY Magpul and to the same standards and quality of the real deal, you are sorely mistaken.
They are all manufactured by a factory in China UNDER LICENSE by Magpul to imitate their design and label. They are not built to withstand the abuse a real operator would endure, as these are not meant to save your life or that of another.
Did it ever occur as to why these PTS products cost less than the real thing? There's obviously a compromise somewhere...
