all they have to do is have a clamp and a low profile. Tell us what gun you have and well see if we can find a decent deal. I know what ya mean though it seems crazy to spend $35+ on a little metal piece. If you like your current one then keep it, the only reason to upgrade is for your hopper to be lower to your gun, and a clamp to hold your hopper better.
well there's NO way im gonna pay $65 for it...I think I'll stick with my little plastic feedneck for now....but yes, my gun is the MR2 in my sig. (still haven't gotten it in yet )...comes in wednesday.
