Absolutely, or Monty’s 14.7 CHF barrel. Adco or my personal favorite Marvin Pitts could both knock that out of the park....But it not just the barrel alone that makes the 12.5 so desirable - it’s the way Monty ported it. Many barrels on the market today run larger gas ports for a variety of reason, the least not being the larger port will cycle all kinds of ammo including lower pressure 223. The 12.5 is ported to run optimally suppressed. I’ll tell you it is hands down the smoothest shooting SBR I’ve shot and I will include my 14.5 Hanson’s in that list, which I thought were unbeatable in smooth shooting - and was until I got my 12.5 Centurion.
You could maybe run one of Clint’s (Black River Tactical) CustomTune gas port. I tried one on a DD 11.5 which was pretty freaking gassy due to a larger port size. It was like my gun got “fixed”. It went from a rough riding Bronc to a mellow mule. Still ran like a scalded dog, as far as slingin’ lead like any good DD CHF barrel would do, but it was a tame beast no doubt. Not far off from my 12.5 Centurion, which shocked the crap out of me.

Couple of questions. I’m assuming the Wolf Gold is .223?
The MEN XM193 is 5.56 right?
My experience with smaller port barrels is that they have a harder time cycling or locking back on lower pressure .223 ammo. Smaller port barrels are by design meant to run optimally with a can or higher pressure 5.56. As I write this I’m like, Fledge already knows this... but I had to learn it with my CA 12.5, trying different buffers and springs and testing with my normal ammo I stock. You could also open the port up a tad, but in my opinion that defeats the purpose behind the smaller port which (again imo) was to build a smoother shooting SBR that didn’t have as much recoil impulse giving you a faster on target response for 2nd, 3rd, 4th, etc. rounds on target. I’ve had this discussion with Monty from CA, but I’m pretty sure I want to run my SBR’s - regardless of the barrel man./length with a can full time and I’ve gotten away from almost all .223 except some heavy .223 I’ve ran in precision guns.

Yes yes and yes. . I was surprised MEN 556 didn’t lock back (both of those cycled rounds however). I listed those ammo types because they are popular and some would find the info helpful. If you are unsuppressed wolf gold only guy, you’ll want a light buffer with this barrel.
I won’t open up the port. I just need to decide whether to swap out the A5 for a carbine... or work up hotter loads... or always suppress it. I’ve got options and look forward to dialing it in.
Interesting, I got the slightly different results with my 12.5" Hodge. Test with/without Q Trash Panda
Unsuppressed:
Hornady 55gr GMX locked back on last round with A5H4 & Green Spring.
Remington AccuTip-V 50gr can't consistently lock back on last round with A5H4 & Green Spring; but has no problem with A5H3 & Green Spring.
Brown Bear 55gr FMJ only consistently locked back on last round when using A5H0 & standard spring.
Suppressed:
Hornady 55gr GMX locked back on last round with A5H4 & Green Spring.
Brown Bear 55gr FMJ locked back on last round when using A5H4 & Green Spring.
Didn't bother to check Remington as it's a hotter round than Brown Bear, so if even Brown Bear has no issue, I don't assume Remington would have any trouble.
So what would be your guys recommendation for gasport size and buffer? Here's what I plan for the build but some things might change. The ammo I'll use is Wolf/Tula Steel Case for cheap training, Hornady Critical Defense for Home Defense, and Green Tip for any SHTF stuff. So the barrel has a .750 gas port and I'll have an adjustable gas block. I'll be using the A5H0 buffer and spring. All with a Hodge Defense 12.5 barrel.
Do you see anything wrong with this? Do I need to get the gas port cut, etc? Thanks for the help thus far gentlemen!
Wolf Gold is basically M193, maybe a touch on the low side of a real 5.56 military load. Nominal 3200fps is what's expected, and the Wolf Gold pretty much gets there, while my IMI M193 gallops out at 3400fps or so. Pretty much loaded to the very upper end of a 223 load and it is reported it is overstocked Taiwanese military ammo. It is one of my primary training rounds
As of now no. But that might change in the future. I live in Canada so Suppressors are illegal. But lately a lot has been going well. Quebec just kicked out the Liberals. And that's saying a lot since the 2 parties in Quebec are Liberals and extreme Liberals lol. And one year from now is the federal election. So who knows? lol.
