Looking at the pressure switch for the Eotech LBS (p/nCFL-053-4) runs $65-$70. I did run across an ad on GA listing the same p/n but they are calling it "  INSIGHT FLASHLIGHT SWITCH CFL-053-4 X SERIES PISTOL SHOTGUN 4" M3X M6X" for only $45. The seller said he wasn't sure if it would work with the LBC...but they look the same, and have the same p/n....am I missing something? Or are they indeed the exact same thing?

I had the exact same switch for an Insight m3x weaponlight and it worked perfectly. It would make sense that they would work. You might even find it on ebay for $20

Thanks for the info. Very much appreciated. I'll give ebay a look as well...
