    Alamo, lots of testing of port size available. Many want manufacturers to disclose the port size so they know what they are dealing with. Adj block works but adds complexity when it may not be needed. Even if you have one, it's more of a set it and forget it solution anyway. I've also read that regardless of buffer, an oversized port also erodes the port more quickly. Overgassing is a result of manufacturers not wanting John Doe know it all from eating up customer support resources cause he shoots the most underpowered cheap ammo he can find. A battle rifle, the philosophy goes, should be ported to the appropriate ammo. I prefer ports that at least work with quality ammo. I wish manufacturers would say which factory ammo has been tested so we work with it. Plenty on M4C have talked about this.

    18" barrel increases velocity. For my purpose it would be a 600m rifle for training. I'd rather spend 60¢ a round in 223 match than $1.40 for 6.5C match. Plus I think 16" to be the awkward middle. For all-purpose, ideally 12.5-14.5. For longer precision, ideally The 18-20. The MK12 is a case in point.

    The 16" Recce platform I think is a fantastic rifle, with a "Recce" set up being about my favorite there is. With a quality barrel and other components, you can reach 0-500m (I limit that because the optics are lower power) easily with marginal loss of velocity over an 18", and with a suppressor, I doubt there's much difference at all. I'm not arguing by any means, it's all personal preference. I have ARs in 10.5", 16", and 18", and shoot the longer ones much more, but my Recce gets the most trigger time. I do love my 18" SPR, but it is a good 2.5lbs heavier than my 16".


    Alamo, the gas port thing has been beat to death online. My WAR uppers supposedly only work with larger gas ports (between .084-.092") but I believe my Rainier gas ports are .080"-.082" (I emailed to confirm but haven't heard back yet) so it's not a deal breaker in this case. But the ideal gas port size for various barrel and gas systems, suppressed/unsuppressed, etc has been asked eleventy-billion times out there.
