I know the buffer thing has been ebat to death, and I DID search - for about an hour - but didn't get exactly the answer I was seeking.
Here's the issue.
So I have an SBR upper, and Ive been loaned for a week or so a differant upper to try. Here's the rub - it's an 11.5" upper from Rock River Arms. Yeah, I know - not really top of the chart - but for the price [read; free] I'll play with it.
Now, if I understand correctly, RRA tends to run their gas ports larger than mi-spec? Or perhaps I'm wrong on that?
If that is so, then theoretically, I should be using a heavier buffer - like say an H2... correct?
I have access to carbine and H buffers. But I'm wondering if shouldn't go ahead and buy the H2 for this, as I don't want to damage anything [since it's not really mine].
If I run too light of a buffer things will slam around and could potentially amage something right? or is the only drawback higher recoil?
I [I]think[I] I'm understanding this correctly, but once I got into port sizes I got somewhat confused.
Any insight or clarity anyone can offer would be greatly appreciated~
