Please Help Need Advice About Buying an MP40

[MxReEfEr92]

Hey Everyone I have the chance to buy an MP40w es thats 10 months old, How durable are the wet sides? Because If this one breaks it would just be cheaper to buy a new one altogether. Any input would be fantastic.

Inspect inside the housing. New wetside is under a Hundo...

They are pretty durable if not physically broken from being dropped, but if the previous owner did not have it lined up correctly you could have heavier wear. A rebuild kit is $20. Very rarely you might also need the ceramic bearing for $15.
