Hello everyone. I'm trying to decide between the Surefire 618FA replacement forend and the Streamlight TLR-1 (using this Picatinny mount: http://www.brownells.com/aspx/ns/store/ProductDetail.as...TINNY+SHOTGUN+MOUNT) for my Rem 870 Marine Magnum. I can get the Surefire for less than $30 more. Although people are always saying that the Surefire forend is the ultimate, I can see a few advantages to the TLR. It's LED, it's possibly brighter, longer run-time, and it can be easily removed whenever I want. Any opinions? Thanks.
