I'm happy with ar build, its a light weight build and I like that but I'm wondering how badly it needs a float tube. I seldom shoot at more than 100 yards so accuracy wise it doesn't seem necessary but it almost seems like it should have one anyway. I'd like to put a light on it so I bought a little rail thing that mounts on the FSB. Thats fine but now I'll have to put a tape switch on and find a way to mount the switch to the handguards. Wouldn't it to be easier to just put on a ring and a vfg in the right place for a thumb to the button? I've been looking at little rests to carry with me for working up loads but wouldn't it just be easier to have a place to mount a bipod on the gun? What do you guys think? Spend ~$150 on float stuff or a waste for me?
