I'm creating a bit of an uncommon HD shotgun in a Winchester model 120 shotgun I picked up at a gunshow. Winnies are my preferred shotgun since I learned on a 1300 20 guage. This 120 has a 24" rifle sighted smooth bore slug barrel on it and wood furniture. I plan on getting the barrel cut down and shortening the LOP on the wood stock too. I put a tac-star extension on it today and want to put a clamp on it and a small picatinny rail for a TLR-1. This brings me to my question; I'm torn between the mesa tactical clamp with the rail on it or the tac-star clamp and maybe a separate clamp on rail for the light. Two parts vs. one and the mesa part would cost quite a bit more. So does anyone have any experience with these parts and/or suggestions?
