Their are a number of excellent BB hand guns. Walther, Umarex, Crosman, Daisy, Gamo and a dozen other manufactures make them. I suggest you do some research, figure out how much you want to pay and then make a decision on what you want. Go to the link below and look at the BB guns and read what the reviews say. This will help you decide.
Loud hand clap
The BB gun doesn't go anywhere it stays in your hand. The BB travels about 100 yards depending on wind, gravity and the weight of the BB.
I use a Daisy Red Ryder BB Gun.
Marksman 1010 is the cheapest and slowest BB gun on the market.
one that you can afford
Impossible to answer. You don't define what "best" means to you.
If its a BB Gun, Then Yes.
Nerf gun
A Daisy pistol model is a hand held gun like the model 15XT that shoots BB's
You get what you pay for.
There is none!
NONE! this is a pellet gun not a BB gun. Using any hard BB will ruin the rifling in the barrel and make the gun inaccurate. Read page 6 of the owners manual it tells you how to load the gun and says nothing about BB's. It should shoot pellets only.
