Here you will quickly find answers to some of our most commonly asked questions.FAQ # 2451 : I have a M4 carbine. It has the 14.5" barrel, and with the Izzy brake it comes to 16". I want to to put a free float quad rail on it. However, I realized the brake is permanantly mounted onto the barrel. That means I can't get the front sight off of the barrel to be able to put the quad rail on. Is there a way around this problem? I know I could use a two piece quad rail, but I would really like to get a free float on there. Let me know if you have any suggestions to help me out.

Ie: easy installation. I noticed that the Model 4 is not a true flattop, so is it hard to find rails that will match up with the rail that comes on the gun? With so many options out there it is completly confusing and sort of frusturating. I guess I would like to see what my options for the Model 4 are and I would like to know if there is anything else I should be aware of that may limit what accessories I can put on my gun. Any information as to what and where I can purchase the right parts for my weapon is greatly appreciated!

If so, which adapter, and at what position do I mount it?http://www.bushmaster.com/faqs/?f=1681Sat, 27 Jun 2009 00:00:00 GMTFAQ # 1673 : This is an FYI to BM Gas Piston Upper Assemply (POF) owners. This should clear a lot of confusion about the Daniel Defense Piston Omega 7.0 Rails. DD Piston Omega 7.0 Rails comes in 2 versions, DD-10501(mil spec) and DD-10502(large diameter). DD-10502 measures 10/16 (5/8) of an inch. DD-10501 measures 9/16 of an inch. DD-10502 is for the BM GP Assembly (POF) DD-10501 is for the BM GP Retrofit Kit (Ares) I bought the DD-10502 but came with the DD-10501 upper rail. I talked to Daniel Defense Support and they took care of replacing the wrong upper rail with the correct one. DD-10501 doesn't clear the BM GP Upper Assembly piston housing. DD-10502 clears perfectly! BTW, the DD rail is top notch! -- Markhttp://www.bushmaster.com/faqs/?f=1673Tue, 23 Jun 2009 00:00:00 GMTFAQ # 1647 : I have a bushmaster carbon 15 97s pistol.
