I went through BRT’s drop-down options then selected the “BRT recommended” size - basically when you place the order they assess the specs you selected in the drop down options and send you the size they recommend. In the case of my SBR it was a .071. You also have the option of just picking your own size as well if you already know what it is that you want or need.
Hodge 12.5”. Mine is sub moa. It is hands down my favorite ar.
Keep in mind that the adjusted gas tube hole is not a direct translation to desired gas port size. Example: if you wanted a .067 gas port using the tube, you'd probably receive a .069 ported gas tube. I used the EZ Tune gas tube as well, and am quite pleased with it. Clint has his stuff figured out.
Yep they mention that on the site so hopefully anybody who wants to pick a specific size on their own keeps that in mind. Me I figured I’d just let them select the size for me because in his posts on here Clint seems to have a pretty good handle on which port sizes are appropriate for what.
Just ordered a 12.5 Criterion Core barrel. I'll let you guys know how it shoots.
Given that they designed it specifically for the applications we are all looking to use it for, I'd be very surprised with any issues.
