Ok gang, I'm about to pull the trigger on a Palmetto State Armory M16A2 style upper with 1:7 twist. I'm planning to shoot 55 and 62 Hornady soft points loaded to .223 power level. Any reason why I should not buy it? I really want an old school upper with non-removable carry handle and 20" barrel, I have zilch interest in flat tops and red dots. Is the 1:7 twist going to work with 55 grain slugs? If it makes minute of coyote groups I'll be happy.
