Review of FAB BM-4

Recommended Posts

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.

Botach is owned by a Middle Eastern person who's company will charge your card and wont have item in stock and will take forever to get the item or refund the purchase...

I was ignoring the vendor chosen and choosing to only focus on the product being reviewed.

 

But yes, Botach has about the worst reputation you can possibly expect to never achieve. Avoid whenever possible.

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.

Sold me something for my 11017 when the part came and did not fit (it was for 1014) he told me he would not charge me for a restocking fee and would only give me credit.

 

Sorry not to answer question, but I couldn't help it.

I just got my BM-4 rail and went to the ATT-tactical site for instructions on how to "modify and assemble". How long did it take you to get yours to fit. Any suggestions on the process?

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.

Where would it say if it is a 1014, 11707, or 11717?:confused: None of those numbers are on my shotgun. All it has is M4 right underneath the breach.

It would say on the box.

 

Also, see if you have a milled recoil tube with notches cut in it.

 

Or see what year your gun was made in.

 

If its a new gun, more than likely it's a 11707, it's been their main model for 3-4 years now I beleive.
