Go to Tiq's Foundry near Anchorhead. That Master Weaponsmith is great, I bought all of my carbines there. EE3, DXR6, Elite Carbine, and Laser Carbine. I'd also do the Nym missions a few times and build up a supply of Nym Slugthrowers too. I have 4 of them, and at 217 max damage, they are good to have.
So, send an in-game tell to Tiq, or to me Sethrak, and i'll send you the waypoint (hehe I can't remember without checking my datapad)
