PP750 internal suppressor replacement

This is meant as silencer/suppressor replacement for SPA PP750 cal. 5.5 mm internal suppressor.
I accidentally lost the originals, so I did this one. I've also put cotton wool outside the K-baffles, works better than original imho.

Each of one baffles are different size to avoid whistling.

Works also with cal. 4.5 mm (.177)
