Mid length AR Gas tube

[aspiringsnd]

My father is in town this weekend and I'm helping him with his first AR build -- and wouldn't you know it, I don't have the right gas tube. Does anyone know where I can find a tube locally this evening or tomorrow?

I THINK high caliber sales in Carmel has some mid length and rifle, little high but had them. Plainfield shooting supply perhaps? Know he had carbine tunes.
