I've currently got a dedicated fore-end light on my 870P, but would like to replace it with a fore-end that has a rail for attaching an M3 or something similar. Is there a product like this made? I just think this type of set-up would be more versatile, since I like the light for home use, but for hunting it's bulky and hangs on the brush.
Yes, Surefire makes the M69 tri-rail forend.
A guy in EE has them for sale.
He wants 109.95 for it.
On a side note, I picked one up at a gun show last weekend for 84 bucks. Brand new, still shrink wrapped.
