"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.

"Very nice, works well with my HK 416! Only problem is that the fuse arrived blown and I had to wait a couple weeks for a new one. Still, it is only a minor problem that can be fixed. The pre wired design is also really nice so you don't need a soldering iron. A great purchase, but I would recommend to get a fuse kit.

"This is awesome. You can see the casting marks on the out side but it come with the 8mm steel ball bearings so it has that extra thickness and it's pre-wired. You'll want to by so lube for the bearings and evike has some great, free, how to videos also.

Pros;
-steel ball bearings
-pre-wired
-selector plate

cons;
-needs lubricating
-shows signs of weak alloy casting
