JohnWichReeves Posted September 15, 2022 Share Posted September 15, 2022 So I got night sights for the M4 and some new screws since they're one time use. My question how much do I tighten the front screw? It keeps turning but I've seen on various places that you can strip the screw if you over-tighten...maybe that applies to Metro sights only. Should I tighten the front screw until it is absolutely tight and ain't moving? Quote Link to comment Share on other sites More sharing options...
Unobtanium Posted September 15, 2022 Share Posted September 15, 2022 I typically will tighten that little nut right up until the point that the wrench begins to ever so slightly move the metal on the corners. I don't know the torque value for this, and it's very much a "feel" type thing. "Snug". YMMV, proceed with caution. 3 Quote Link to comment Share on other sites More sharing options...

Blitzkrieg components are more durable but regardless they don’t need to be tightened past the first bit of resistance.
