Does anyone sell a front side sling mount for the FP6 shotgun? It would look something like these. The difference is that the FP6 has the mag tube detent in the middle of instead of offset like the 870 and 590 so those will not work. I find it very strange that there is a rear sling attachment point but nothing in the front.

I tried looking at Brownells and did a google search but came up empty.
