Postal Bob Posted June 15, 2015 Share Posted June 15, 2015 Does anyone know what size fiber optic rod, the JM Pro series shotguns use? Mine melted, and I need to replace it. I tried calling Mossberg, and they literally told me they don't have the specs for that, since they only sell the whole sight, and not just the rod.

BitchinCamaro Posted June 15, 2015 Share Posted June 15, 2015 I'm going to be in the garage messing with my 930 in an hour or so. I'll get you a measurement if I can. Did yours melt via shooting? Link to comment Share on other sites More sharing options...

Postal Bob Posted June 15, 2015 Author Share Posted June 15, 2015 Yeah, doing shotgun matches. Those barrels get burning hot after running a 28-30 round stage. I've got mild burns by accidently touching the barrel right after. Link to comment Share on other sites More sharing options...
Nickoli Posted June 16, 2015 Share Posted June 16, 2015 Just replace it with the hi viz. I just did this on mine and I like it a lot more than the factory front sight. They are a lot brighter as well, mine started to get dull after a couple years. Link to comment Share on other sites More sharing options...
