I am down visiting for the weekend and I am looking for suggestions.

Does two river arms have an actual storefront?

I should have said I was looking for mainly AK stuff.

pretty sure Big Boys is their retail outlet.
call either for confirmation

Big Boys is retail.

Also, you could check out Cold Hand Arms on broadway ext just north of 63rd.  It's small but good.

okay, no, Two Rivers Arms does not have a storefront.
If they have what you want, i'm sure you could pick it up at their manufacturing  facility, which is a oil field era tin building on south Bryant..
at one time 2 Rivers' web site stated they were "a enterprise of Big Boys Guns and Ammo, which acts as   it's sole distributor"  it does not say so now.
in the past Big Boys have had 2 Rivers' Tabuks for sale in their store, to my knowledge the only retail outlet to do so.

ergo, i believe Big Boys is their retail outlet, i could be wrong.

you're probably out of luck till Tuesday anyway, except for H&H.

If you have time just stop by two rivers and they will shoot the sit with you and show you all the cool toys I go there all the time.
