| I think the Superior Arms lower has a trigger creep adjust screw built into the lower that others don't but that should be about the only real difference from any of the other lower reciever brands difference. All of the lower recievers do the same job some are just "prettier" with a nicer/darker finish. But sometimes that darker/nicer finish can be bad if you care about upper/lower color match as unless you buy an upper with that same finish you can have a 2 tone gun. So basicly if you want the upper and lower color to match getting the same brand of both would be the best bet but if you just want a gun that goes bang the finish and color match doesn't matter. |
