Richard B Posted August 18, 2021 Share Posted August 18, 2021 I picked up my Benelli M4 a few weeks ago and my front sight is loose. When I tried to find a wrench that would fit they were all too thick to fit and I used needle nose pliers but the sight moves when tightening. Suggestions? Surprised it didn't come with a cheap wrench. Not sure why the front sight would need to be adjustable Quote Link to comment Share on other sites More sharing options...

bigoo7e Posted August 20, 2021 Share Posted August 20, 2021 Too bad Snap-On doesn't make these any smaller than 10mm, it would be perfect have one of these to tighten down and/or swap sights out. 10 pc 12-Point Metric Flank Drive® Ratcheting Box/Speed Open-End Combination Wrench Set (10-19 mm) | SRXRM710 | Snap-on Store (snapon.com) Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted August 20, 2021 Share Posted August 20, 2021 The ratcheting or closed box wrench type won’t work since there isn’t enough room to slip the wrench over the end of the nut in the tight space under the front sight tower. I bought the Craftsman ignition set about a decade ago. 1 Quote Link to comment Share on other sites More sharing options...

Stamped out of flat stock it certainly wouldn't take a whole lot of engineering or tooling up. Kinda like the "SRO" tool, only one dimensional. My 2 cents.........
