I just checked the Date code: I have a "CS" stamp which correlates to 2017 manufacturing so my best guess is they changed the size of the magazine tube bracket in the current production models.

Correct. I have metal to metal contact. Both the plate and the forend are the same outer diameter/dimension.

Sure thing. Here is two.

I have the condor 6 rd ammo card mount on my BM4 with the Velcro method. The hold is very firm and stays in place. Weight it at a minimum as it couldn't possibly weight more than an ounce or so. It works great for me. I had/have the mesa tactical 6 shell holder. Its nice but obviously adds a good bit of weight and size vs. the ammo card pulls off if I do not currently need it.

Happy to help.

Yes, it appears that the rail butts up to the magazine tube bracket and creates a gap preventing the barrel from going into full battery into the receiver. I have metal to metal contact and was just wondering if there is anything I can do before I go making mods to a $2K shotgun or chew up an discontinued surefire rail. kind of between a rock and hard place. Do you have any pics of how much to sand off the rail?

Hi yall. I know I'm late to the surefire m80 game seeing how they don't make them anymore, but was the fitting issue ever resolved or does anyone know how to make a non-fitting rail fit? I'm am having some fitting issues with mine I just got from a friend. Thanks.

Hi yall. First post here. About the RMR SYNC mount...I had an individual text me today trying to sell me his but I am looking for the Scalarworks BOR100 mount. He still had it if you want a nice used one. Great condition. Just text him. His number was 206-799-2816. Tell him I am the guy he text earlier today (he found my WTB ad on ar15forum.com). Hope this helps.
