Recently an esteemed member Ryo brought something to our attention: he had noticed that it was harder to flick the LMT safety from Fire to Safe, and vice versa. While our selector is smoother and has less play while engaged in either position, ours required less effort to lock/unlock in Safe/Fire.
We had mentioned earlier that we made some improvements to the detent holes and detent groove, so here are some detailed looks:
The cast selector's detent holes are slightly wider and less precise than ours. The detent's diameter only measures 0.12, our detent hols diameter are not much bigger than the detent itself, thus it has less play while locked in Safe/Fire positions.
The detent groove on the cast selector is very shallow, so it does require more effort to rotate it (lifting the detent from its hole and onto the groove). Notice the far deeper detent groove on our selector and its ramp (from the detent hole leading to the groove), this arrangement makes it easier for the tip of the detent to be lifted onto the groove, it's smoother, not the rather abrupt and hard path without a ramp.
Battle Arms selector on left, cast selector on right. Notice the difference in contact area between the detent and the groove.
The finely machined detent holes and groove vs. cast, differences are easy to see.
Thanks to Ryo for bringing it up, we wanted to take this opportunity to display some differences and improvements we made that are largely transparent to users
