The story of my overgassed DD MK18 & DD CS

[Naphtali]

It really felt like a new gun, with the same Springco Blue, and H2 buffer. It shot amazingly different.

Other than less gas to face, do you mean there were other improvements in the carbine's performance? I have 2 DD Mk 18s with the oversized ports, but with Surefire SOCOM suppressors, there are zero gas blowback problems with mil-spec ammo. So I was thinking there was no reason to swap mine for the smaller port size... though I have heard there may be reduced recoil or other benefits in doing so.

So what other benefits, if any, did you notice? And would you consider those benefits great enough to be worth the hassle / risk of swapping parts for a smaller port size in a gun where overgassing is not an issue?
