We show that the phase spaces of a large family of line operators in 4d Chern-Simons theory with GL$_n$ gauge group are given by Cherkis bow varieties with $n$ crosses. These line operators are characterized by Hanany-Witten type brane constructions involving D3. D5. and NS5 branes in an $\Omega$-background. https://parisnaturalfoodes.shop/product-category/beard-balm/
