Took the WE MSK apart at work when it first arrived nearly a month ago – forgot to post these until now.
Next 3 pictures show (non-reciprocating) charging handle operation:
Barrel length in MSK is slightly longer than WE M4A1, even though hop up chamber is identical. This particular one’s barrel was coated in some sort of black stuff – we already sent off a picture and note about this back to James @ WE.
Detailed photos depicting size of bolt stop face – should hold up fine based upon sheer size in comparison to the WE M4 (my WE M4 open bolt converted bolt stop has worn out countless times now).
Comparison of screw pattern for WE MSK butt pad (left) and PTS Masada folding stock butt pad (right).
No rubber plug on storage compartment in WE MSK folding stock storage compartment, unlike PTS Masada stock.
PTS charging handle in WE MSK. Not as precise of a fit as the original WE part, but it does click into place, and function exactly as it should.
