Why don't we use the 30 RAR upper for our 450?

[gtoboi65]

I was just doing a little research (still trying to educate myself on ar's) and came across the 30 Remington AR. It uses our parent case with a slightly larger rim (so we can't cycle and shoot it out of our 450 Bushmasters) and an AR 10/15 hybrid upper receiver. They did this to safely increase pressures with the 30 RAR. Could we benefit from this hybrid receiver, delivering even greater performance from our rifles?

Just a thought

Some one please educate me!

Might be able to, but just try to buy one of those receivers and the expense won't justify the little bitty increase you MIGHT get from your loads..

Never thought of that. Money is always the deciding factor.
