"Didn't quite match picture(s). Mine came with bearings on the bevel gear and bushings for the spur and sector. Also came with a metal bearing spring guide, which I wasn't expecting, so was a nice surprise. Built w/a hodge-podge of parts and it runs like a top.

"I'm gonna keep this short and simple. I wouldnt buy this if I was building a DSG, but in an emergency (why I ordered it) it is just right. In fact, after a few months of use it seems just fine. Doesnt 100% fit in a JG M4A1 Carbine, but nothing a little modification wont fix.
