I had asked around as well and didn't get much help (even Bud's online). Ended up going to a local gun shop (Wilcox in Newport News, Virginia) and he ordered one for me. He called me to make sure it was the correct part number 11711. Benelli says it is about 60 days until delivery. We'll see.
Well this was my first post and it didn't show up. I thought I did something wrong so I made another post.....hence the dual posts fellas. Anyways, so far I'm impressed with the M4. Wife will be shooting it next weekend. Here's how it looks now:
Thanks for the compliments and advice fellas. I shot it for the first time.....very nice with much less recoil than expected. Trying to post another pic.
I use it on top.
Not sure what your intent is, but there are several reasons to choose certain products. Many people prefer a red dot sight for their shotguns.....I have yet to make that final determination. I am trying several different options for my shotgun and will end up using what works best for me. Have a nice evening.
