OK, thanks, I'll check that out. I've yet to fight a Sentry Bot, but I have one waiting that I can use north of Sanctuary, but it can only be used a few places.
I've dropped my sniper rifle I had (which was actually 51 damage I found out), because I found a Hardened Sniper Rifle that's 64 Damage. I think I may put a suppressor on it.
I'm currently level 16 and have been unlocking quite a variety of perks, though too busy to do any serious modding yet.
The last one that sucked me in was Lone Wanderer. It's quite nice to have 50 more carry weight and 15% less damage just for not being with a companion. I don't even need PA to carry PA weight.
It seems to me these level up games to a point make damage increasing mods a bit useless, because as you level up, so do the weapons you find.
I remember in Dead Island I was always finding better damage weapons not long after modding ones.
