I have two M3's and both of them have stripped one M3 thread in different locations along the top rail. The very first time I took apart my M3 and removed the top rail I immediately noticed how shallow those M3 top rail screws are. I make it a point to use my torque driver and only use 10 in lbs when threading those in. The top rail is 8mm thick with a 3mm counter sink. So the M3 x 8mm screws are only threading into the module under the rail with 3mm of M3 thread. That's not a lot considering the alignment of the entire gun is dependent on that top rail keeping all of those modules tight and straight. FX really could have gone another 4mm and used M3 x 12mm instead so that we can get some torque on those screws.
Anybody else run into this?
