I just bought a leather NATO strap(I don't got yet), but I just realized the spring bar between case space only less then 1.4mm. Now I worry I just wast my money to get the NATO. Did anybody know 1.8mm thick NATO can force fit the mk40? Otherwise I will just gonna buy another nylon one(1.2mm thick.) Thanks
If it won’t fit you could ask for curved 20mm springbars at your local OD. Probably will fit better then
Oh. I don't realize someone answer my question, I just sit to make curved my spring bar, and it's work! Now my mk40 have nice leather NATO strap!! Happy and it's look awesome!
