Searching for something to measure but I will post it.
The barrel is a legit heavy FBI profile colt sealed in a blue bag. I’m just hoping that it was ported the same as others in the market.

Got sidetracked with a few weeks of travel for work on top of packet weekends. Also got discouraged looking for pin gauges to measure. I’m leaning heavily toward just getting one of your gas tubes but I would like to know the actual size of the GP.

In addition to the excellent gas port advice above, check out the Vltor A5 H2 with Springco Green. I find it to be a very forgiving combo.

From personal experience AU is shady at best. The HRT barrels are not exclusive to AU.
Well to be specific they said the HRT barrel with the shaved FSP were exclusive to them. I have know idea if it’s true or not.

Thanks so much!
Interesting. So if that turns out to be the case with mine, what size gas port/tube would you recommend? Would like it to still be able cycle Brown Bear, etc.
If the Crane spec for 10.5”s is .070 shouldn’t 11.5” be a bit smaller? Thanks!

.069 is a good size unsuppressed.
50/50 mixed can be smaller.
