Thank u for your info everyone but iam not an LEO and i do not have an FFL. In fact iam soon to be a CA resident. In other words Iam F***ed. I like the pic and thanks again.
One thing you should think about is if u want to put a skeleton stock on your M4. The early model Benelli M4's with the rollmark L.E. have a different recoil tube that will either not except or fully collapse the skeleton type stock.
It took my brother and i about one hour or so. It helped me to grind one side of the BM-4 at a time, then take that side and place it on the shotgun to check the spaceing. It was hard to see were the BM-4 needed to be grinded when both sides were on at the same time. When both sides were the same i fitted it on the shotgun nice and snug then tightend it down with the screws. The top rail of my bm-4 is slightley off center and a tiny bit high from the one on my M4.
Thanks for the heads up!, but i think ive already been ****ed over. When i orderd my BM-4 i also ordered a UTG fore pistol grip for 15 bucks but it was not in stock so i didnt get it in with my order. I will have to check but they said my card was not charged for the grip.
I just bought a BM-4 polymer 4 rail forearm a few weeks ago from Botachtactical. It did not come with any instructions for installation. I have a Benelli M4 model 11717(desert cammo) and i could not get the BM-4 to fit on properley. I found a link by ATT tactical that had instructions to modify the BM-4 so that it would fit on the M4. I followed the instructions and got the BM-4 to fit. The BM-4 fits really tight and took a good beating at the range. I used a fore pistol grip which gave my M4 great control and comfort when i shot some three inch oo buckshot. My fore pistol grip actually broke off the BM-4 after a few shots. After i was done at the range the BM-4 was still tight and was not damaged by the fore grip breaking off.
picked up a Benelli collapsable stock +two shot extension for $925.00 on gun broker. three more going for about the same price without the extension.sellers market hope it helps give u an idea for selling price. one guy tried to sell one for $1200.00 but i think hes down to $900.00 now.good luck!
