So you've purchased your first red dot sight. But the night before your first skirmish you realise "Hang on...what if this gets hit by a bb? Will it break?" The short answer is, you'll be lucky if you get away with a scratch.... But never fear I have come up with a step by step tutorial to make an effective (albeit temporary and ugly) clear scope protector!
Step 1: Find yourself some tinfoil / aluminium foil
First of all you will need about 25 cm of tinfoil / aluminium foil
fold the tinfoil / aluminium foil to double the depth you want you scope protector to be and continue folding it over itself until you cant go any further. Then simply fold it horizontally in half.
