The cheapest airsoft sniper rifles are aroung 100 USD or ~60 pounds. Besides that if you want a rifle that will not break after a few months you will need to pay almost twice as much.
If both pieces have the correct 20mm weaver rail, yes it will mount fine.
honestly i do not think it is, i am 13 and i weigh 73 pounds, and i am doing just fine but if you are under 60 pounds i would see a doctor about it
yeah, you may be a little under weight but 120 pounds is fine.
A fine rifle
It depends on what type of gun. If it is a small to medium sixed gun (handgun or small rifle) 10 year old children can fire them. If you're looking to shoot shot guns, assault rifles, or a sniper rifle you may want to be over 13 or 14. If you're an adult you're fine shooting basically any gun.
I have seen these fine made rifles selling in the range of 800-1200 dollars for a rifle exhibiting overall good to fine condition with the proper markings on the wood and metal,and a fine bore.
They produce a fine product.
From experience I have found that snipers are tricky things to shoot there harder than varmints to shoot. You need to sneak up on them and get in close before you shoot. at this close range even a .22LR with a 4x32 scope will be fine. I advise using a head shot as a wounded sniper can be very dangerous. If chased climb the nearest big tree.
It's a fine inexpensive rifle for youth. It is designed for learning how to handle a rifle safely and for plinking at targets. It is not a hunting or competition rifle, but is designed for fun.
Well, it depends how tall you are. If you are under 5'4 then you should probably lose weight. If you are above you are probably fine.
1863 was a civil war 58 caliber rifle. there is no history unless you fine the owner's family and the family knows details pertaining to the rifle.
You should have added you height. If you are 5'4"+ you are underweight, but not by too much unless you are like 5'7". If you are 5' you should be fine.
