Factory plus 2 Extension Part# 80087


Recommended Posts

Will the factory spring in my Benelli M1 work with the plus 2 extension, or is there another spring I have to use?

Thanks, Scott


The factory kit I got for a Benelli M1 came with a longer spring that had to be cut and came with instructions for a starting length and minimum length.

Fastlane, was that a plus 2, or plus 4 extension?



That's been a few years ago, but as I recall it was a 20.5" bbl and the extension was just a bit shorter than the muzzle. It must have been a +4. How much longer is your stock spring than the tube w/ extension? I recall they said to start with the spring cut about 16" longer than the magazine w/ extension and no less than 10"-12" longer.


As a side note, the recent Benelli +2 extension kit I installed on a SNT came with a long spring with instructions for trimming.
