survival air rifle

a normal air rifle or firearm (if legal in your country ) can be modified to be smaller and more compact with features such as a screw in hollow stock which can be filled with survival items or a folding stock with a compartment for survival items the measurement for a legal uk air rifle over 6ft lbs is 60cm overall length with a barrel of 30 cm minimum i will add to this post as i continue with the project ,the first thing i wil do is cut off the stock i .ll mark the stock with tape so the guns overall length is over 60 cm i,ll also make sure the barrel is over 30 cm then cut off the stock, now the stock has been removed you need to round it off then dril a hole which will be your pivot for your folding stock to make the stock you,ll need 2 peices of 5mm aluminium my measurements were 1 inch by 8 & a half inch long but you could make it the same size as what you already cut off you also need a small shoulder peice which could be the end of the old stock cut off take a look at the pics ,drill a hole through both bits of ali about half inch from the end to make a kind of hing then put a bolt through as in pics now you need to srew on the butt piece just a few holes then screw on now the easiest way to lock the stock in place when open is to drill a hole and put a pin through attached to the stock by a piece of paracord so as not to lose it
