I have on offer the following sound moderators for members of the site, A-TEC CMM 6.
They are made of steel and can be stripped, their performance is quite unbelievable for the size of the moderator. They weigh in at 475g depending on baffle configuration, length is 7" again depending on baffles.
A few stalkers use these on here already and they are a superb piece of kit.
Offer price is £190 posted
PM me please for further info.
