Waltershumate2 Posted March 17, 2009 Posted March 17, 2009 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. Quote

Commando Posted March 18, 2009 Posted March 18, 2009 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... Quote
Duggan Posted March 18, 2009 Posted March 18, 2009 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. Quote
Waltershumate2 Posted March 18, 2009 Author Posted March 18, 2009 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. Quote
alisske Posted March 19, 2009 Posted March 19, 2009 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. Quote
huklbrry Posted March 19, 2009 Posted March 19, 2009 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? Quote
Waltershumate2 Posted March 19, 2009 Author Posted March 19, 2009 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. Quote
huklbrry Posted March 19, 2009 Posted March 19, 2009 Why the F**K would FAB Defense make a product that doesnt even fit the firearm that it is exclusively for??? I think my brain is freakin' hemorraging:eek: Quote

Waltershumate2 Posted March 20, 2009 Author Posted March 20, 2009 I did hear that the BM-4 was made in the early days of the Benelli M4 and that it fits the M1014 models but not the 11707 or 11717's Quote
huklbrry Posted March 20, 2009 Posted March 20, 2009 Where would it say if it is a 1014, 11707, or 11717? None of those numbers are on my shotgun. All it has is M4 right underneath the breach. Quote
Duggan Posted March 20, 2009 Posted March 20, 2009 Where would it say if it is a 1014, 11707, or 11717? 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. Quote
Amsdorf Posted July 15, 2012 Posted July 15, 2012 Sorry, for the necropost, but....have these gotten any better? Quote
jkewl999 Posted August 31, 2012 Posted August 31, 2012 HI could someone please send me the link of the instructions how to modify and install the quad rail on the m4 i waited to get this rail for like 6 months and thought it would be fitted on directly and only to see i need to modify. Please someone send me a link or good isntructions where exactly it needs trimming and how much i really want this on it. Thanks Quote
Sammy Posted September 12, 2021 Posted September 12, 2021 Day late, dollar short. Thank you Benelli Forums for wishing me happy birthday before anyone else. Regarding the FAB Defence handguard, I do feel it is one of the best options available due to weight, durability, and maintaining original handguard profile. I am very against polymer rails on firearms, however this handguard has proven several times over to hold it's strength. There is no question of it's difficulty of installation and it prevents me from cleaning the firearm. Just cleaned my Benelli M4LE 11721 for the first time in 16 years and working on the reinstallation of the handguard. For the sake of 16 years, my Benelli M4 has gone through thousands of rounds and never missed a beat. Thank you again Benelli Forums. SAMMY! Quote
