I've been going crazy with all the options out there for various parts that I'd like to add to my AR-15
Colt LE6940
From scopes and grips to lights and lasers, i'm trying to narrow it down, not go "over board" and avoid buying something that ends up sucking bad.
I dont have any "preference" as in distances I shoot, how often, etc. All i'm really looking for is "Cool" (I know...I hold my head in shame, but I gotta be honest with myself...it's what I want)
All of your opinions are absolutely welcome...please tell me if a "bayonet sounds stupid"

but at least tell me why
I'll give a list of each part im looking for, then a list within each part that i've considered buying. If any of you have had any experiences with the ones listed, please don't shy away from sharing it!
Bipod & Grip
(Perhaps combining them)
I haven't looking into many "grips" by themselves, but am certainly open to whatever. So far im leaning towards a combo item, but am not educated in the ways, so im not sure what are the pros/cons
I like
this one based on looks.
But
this one has a light holder (anyone find that useful)?
And I really like the looks of
this but not sure if it's worth the time?
Optics, Scopes, & Lasers
Basically targeting system(s). My initial thought was doing a short range/long range rifle by doing a laser with a long range scope. Don't know the differences between Holographics and Red dots, but have not ruled out using one of them instead. Listed below are the different options I was considering buying
K-15 Laserlyte Green Laser
EOTech EXPS3-4 Holographic Sight
Barska Illuminated Red Dot 3x Magnification
Mark III Tactical Scope
Miscellaneous
Bayonet
