I sorry for speaking to soon.
I checked all the gun stores around me and they all got some in months ago but sold out quickly and will not get any more in due to the atf.
Here’s a side story though,
My bud at the Atlantic guns "where I bought my m4 and 2rd tube" told me he had 2 or three in not that long ago but one of the new young guys working there "he thinks" bought them one night when he wasn’t there and now he’s trying to auction them off for big $. I know it might be true, Also this store Received 4 m4's and sold them all but kept the chokes and tubes that were in the box as a set from benelli separate and only until later they put them on the shelf’s. I called them about mine and they said there sorry the new guy must have forgotten them but the don’t have them now please call benelli.
