M4 Sight Nut

I asked this before but have yet to get an answer, has anyone been able to get an actual specific size wrench for the front sight nut on an M4 shotgun? I can't get a hold of anyone at Benelli that seems to know this...

 

Looking for an exact size wrench, I am sure one exists, how would they put them on at the factory...

A 5.5mm (7/32") open ended midget wrench is what you will need.

That's a tad big. I just installed my mepro sights today and used that same wrench. It was a little loose so be careful when you're tightening it down. LOVE the sights though. :)

I used the 5.5 and haven't heard of anyone having an issue getting it on or off while using that size. If there was an issue, Brownell's has replacement nuts.

They are VERY easy to round, as the nut Benelli uses is very soft. I suggest buying a couple of them for a few $$ at the same time you order your sights. It is a good back-up if you round 'em. I consider it a 1-time use as stated due to the nylon insert.
