I thought I'd show my latest attempt at a cheap cheek pad for the metal folder.
I got some 1/2" foam pipe insulation and a roll of veterinary wrap and took a 5/8" strip off of the length of insulation to make the proper diameter.
I used the adhesive strip to attach it to itself and then wrapped it with latex vet wrap.
Here it is with the whole reason that my virtual ears initially pricked up at the mention of some sort of 'CZ' AK-style rifle - a family heirloom CZ vz.24 pistol marked with Czech military acceptance proofs from 1936.
It feels nice and cozy and gives me a good sight picture. I was able to get 3 layers of wrap on without interfering with closing the stock. Previously, I used just the wrap on the folder and after awhile the many layers all fused together into one firm, rubbery layer so I'm thinking that once it 'cures' it'll make a nice, firm coating for the softer foam core.
The cost of materials used was probably less than a dollar but I paid about $5.50 total for the wrap and a package of 12' of 1/2" insulation.
