trevor1030 Posted September 18, 2022 Share Posted September 18, 2022 Hi all, curious if anyone else has a crooked front sight post? My Benelli M4 I just noticed today is way off to the left is there anyway to adjust this or am I just screwed? Thanks Quote Link to comment Share on other sites More sharing options...
StreetSweeper56 Posted September 18, 2022 Share Posted September 18, 2022 One of mine was off as well. You can adjust it with a small, specialized 3.5 mm wrench (available on amazon) but the threads are easily stripped on the OEM. I replaced it with a post from Blitzkrieg components. https://www.blitzkriegcomponents.com/benelli-shotgun-sight-posts.html The threads are not so delicate on the replacement. 3 Quote Link to comment Share on other sites More sharing options...
benelliwerkes Posted September 18, 2022 Share Posted September 18, 2022 It has always been a 5.5 mm nut on the front sight. Has something changed ? Thanks. 1 Quote Link to comment Share on other sites More sharing options...

You're right, I mis-spoke, it's 5.5 mm. I should have proofread my post. Quote Link to comment Share on other sites More sharing options...

Great work there, Benelli. Nice attention to detail. 🙄 1 Quote Link to comment Share on other sites More sharing options...
Evolution Posted September 19, 2022 Share Posted September 19, 2022 Yeah, the design of the front sight is such that you can move it laterally for windage adjustment first, rather than using the rear sight to adjust for windage. It moves laterally, move it to the right to adjust POI to the left and move it to the left to adjust POI to the right. The same as an M14 rifle or M1 Garand. Proper procedure is to first move the front sight to obtain windage zero and use the rear sight only if the windage zero cannot be obtained by moving the front sight laterally. Optimally, the rear should be able to stay centered-with all the adjustment needed to zero windage gained by moving the front sight first. The problem with the Benelli designed front post, is that the post itself can spin sideways on it's axis while you tighten the nut that secures it, resulting in a sideways tweek of the post.

trevor1030 Posted October 2, 2022 Author Share Posted October 2, 2022 Does anyone know where I can get another screw? I like Benellis front post design but I managed to strip the screw today trying to adjust it… I wonder if they warranty the barrel/sight.

Kahamu Posted October 2, 2022 Share Posted October 2, 2022 I would just email their warranty dept. I lost some pic rail washers and emailed them. They sent them to me free of charge. Quote Link to comment Share on other sites More sharing options...

RxArms Posted October 2, 2022 Share Posted October 2, 2022 Has anyone ever had an issue with the front post centered and the rear peep centered NOT shooting straight? Quote Link to comment Share on other sites More sharing options...

Benelli warrantied them. It seems mine was brazed in the wrong spot as well. However mine has aftermarket work on it from Agency Arms, so im curious if they will even warranty it. Because my front sight tower is definitely brazed in the wrong spot, no matter what i do it is off to the left almost canted if you will. Very bothersome as it was a very expensive gun. Thanks!

StrangerDanger Posted October 3, 2022 Share Posted October 3, 2022 Sucks to hear that. Benelli may play nice with you about it. They’re going to almost certainly want the whole gun back to check headspacing. I’m not sure what work you have done from Agency. You have some options available though. Take off 18.5” barrels sell for around 500-600 these days. You could also just ditch the front and rear iron sights entirely and run an optic clutter free. This is the route I’ve been going for the past 4 years or so. Quote Link to comment Share on other sites More sharing options...
