You have to ask yourself if your 13 x year old son can take the hits, as some at that age can`t and Cry with pain, I`m sure you must of known this anyway ? ALL boys want to shoot guns and as a father of x 6 sons .... I know !! with me, I waited until they were x 14, But a huge amount of Dads take their Sons as low as x 11 years of age, this as a Father is up to you !!
