Tweak:

My current upper is a 16" DISSIPATOR (given the gov prof treatment by KKF).  As you know, this setup uses a CARBINE length gas tube setup.  My question is this:  Should only 14.5" barrel users worry about using an "H" buffer because of the increased gas pressures generated by the shorter overall gas tube length?  And is my current combination (A1 length stock with standard buffer + carbine length gas system) reliable as it can be?

I have about 3k through her, but I've only done a couple of 3 mag dumps.  The only malfs i've had have been mag related.  I think i should do a couple of more mag dumps just to see what's up.

Thanks.

Oh and by the way, is there a link to show at what round counts one should change certain parts?
