3mm Lock Nut for Benelli/Beretta Shotgun Front Sight
These lock nuts are an upgrade from the factory nut and lock washer on Benelli and Beretta Shotguns with the elevated front sight and aperture rear sight. These nuts are made as one piece with an external-tooth lock-washer integral with the nut which makes installation far easier. Threaded for 3mm x 1mm threads which is standard for these type of front sights and fits our Benelli/Beretta front sights. Save yourself a lot of hassle by using this instead of the factory lock nut. Made of Steel an attractive and corrosion resistant black-zinc finish.
We include one of these with our Benelli/Beretta front sight posts. But offer them separately in case you need more or want a spare.
Wrench needed to install these is a 5.5mm.
