Hi ya all AR experts,
Because of Obama effect, I'm thinking about getting this AR 15 .223 lower,
But there are so many to choose from.
I have 20" Colt upper in 1 in 7 twist with flash hider bought it 10 years ago.
So I think it is about time for me to finish the project.
Are these upper shares the same parts ?
or is one better then the others ?
I thank you for your inputs.
