Samson does make an MRFS R 12" rail system anbd we have them in stock.
The offset will fit any MRFS rail systems and they can be mounted on either side.
I suppose it will fit an MRF, at least the early versions built by Samson. I don't know if Troy's supplier changed the design of the cooling fins or not. If they are the same, it will work.
This version will not fit other versions of rails that I know of.
Tactical_Operator,
The US Army did not spec it for all Soldiers. It was requested specificly by the MP BN that made the purchase. I photo shopped the unit number off the rail at the request of Samson MFG.
I am sure if you have a good ear to the ground, you will know who is deploying, so you will know who got them. I am not going to make a habit out of calling out unit number for our guys going overseas.
SOCOM did not order the offset as they are not currently using the MRFS.
They ordered the Quick Flip (left and right versions). They are also adding additional Aimpoint 3Xs to inventory.
