I'm looking for a flat (non-sloped) MIL-STD 1913 accessory rails that can bolt onto a US M240B. I am not looking for a riser. I am looking for one that can mount under the heat shield, so the factory bipod can be replaced by a Grip-pod (or any forend grip). Also, I think you can, but does any one know for sure if the factory bipod can be removed and the rifle still maintain 100% functionality?
The vehicle mounted variants don't have a bipod yet look to have an identical barrel/gas regulator setup. From my memories of the MAG-58, there's no technical reason I am aware of why the bipod couldn't be removed and the weapon operate perfectly normally (assuming it could be aimed of course...)
As to the Grip-pod, a Picatinny rail (or 2) would have to be fitted under the gas regulator (and perhaps remove the heat shield) as specwarries do with M249/Minimi's. This would need the removal of the bipod to accomplish, I presume? Such a handle would be a piece of cake to install if a Picatinny rail could be fitted and there are handles around that have their own little bipods stored within the handle...
A quick search on Google revealed that the US does indeed have an M240B "forward rail mounting system" program, presumably to address the same concerns as you have. Couldn't find a picture, but it'd be virtually identical to that of the M249 I'd reckon...
