Has anyone else noticed the lack of unique weapons in new vegas?

A good example is the Laser Rifle...In FO3 there was like 4-5 unique variants of it.

There is only 1 in new vegas...Not much to choose from there.

Aside from the unique version of a weapon, you can mod a normal version...but your choices are limited there also...either you use the Mod or sell it

No choices.

I want to be able to choose from things like thermal scopes, longrange, and other things....All-In-All I want more MODS!!!

( a mod that increases your chance to collect spent energycasings would also be appreciated)
