So the real question is.. are eye guards considered points or no. In like a spike only unit. Or a 3pt min, could he have a split main with a 2" browtine and be legal ?
Yes to both questions.
As long as the brow tine originates inside of 4" from the base of the antler, it has no effect on the spike ruling.
And yes on your example. In a 3 pt minimum area, a fork with a 2" brow tine would be considered a 3 pt, and legal to shoot.
