Who makes the strongest upper receiver?

[kamrr4437]

I agree with you lr. I should have been a little more clear in my first post, as I definitely think a heavier upper reciever is beneficial, I just cant personally justify the cost of billet over, say, the heavy walled DPMS lo pro. that thing is a beast. Now, if I were going any longer than 24", I would probably go the little extra $. I think Ill be fine with the DPMS with a 22" at .800 diameter.(I hope )

Im confused i thought your barrel was 24 inches and you had a diameter of 1.3" on yours already? You must have 2.
