110 Tactical sling stud distance

[bnewt3]

Anyone know the distance between the front 2 sling studs on the 110 Tactical? Im looking at either a BT15 or BT17 rail and I want the shortest one that will use both holes.
BT15 C-C spacing 1.76-2.78"
BT17 C-C spacing 2.2 – 3.5″

For anyone curious, its very close to 2.5" So the BT15 would work, but I only found the BT17 in stock so that's what I got.
