I assume you are asking about the "Daisy model 21 Side by Side BB rifle". This model went out of production in 1972 so it would be very hard to locate one. You could have a custom one built ( search the web for "Custom airgun stocks") or locate a shop that repairs air rifles. See the link Below.
I would start with Daisy air gun company. See the link below. contact Customer service.
I would do a web search for "air gun repair" or see the link below.
I got one years ago from Gun Parts in New York.
There is no law that says that.
daisy is older, daisy is 21, peach is 20 though peach has had mroe experience travelling the stars (peach is actually rosalina by the way)
Federal law is 21
Are you aware that the model 25 is in production again. There are 21 different variations of the model 25 before the new one came out. So here is what I suggest. Daisy has a service to evaluate older Daisy air guns. See the link below
No. You will need the correct nails.
Federal law = 18 for long guns and 21 for handguns
gun salute ? 21 Gun Salute21 GS
It depends on where you are and what you mean by "license." In the U.S. in most states, you have to be 21 to get a handgun carry permit. In most states, you do not need a license just to own a gun.
You are probably thinking of a 21 gun salute, not a 21 gun suicide. It only takes one gun to commit suicide.
