Hi David
I had one made by jim baker, jim as started making moderators range of calibres and fittings,
I went to see him to test fired one and i must say the Sound reduction on my rifle(22-250) was ace
, i had a T8 on my rifle but this new one offers a lot better sound reduction.
It is made of stainless steel and is a sealed unit consisting of a series of welded baffles forward of the muzzle, with a large rear expansion chamber that sits over the barrel its powder coating on the out side , the powder coating can be done in any colours, jim said i could have a pink one
but the best part it will not rust out
, will not need cleaning
and jim said the more i use it the quieter it will get.
Length x Diameter (mm): 280 x 40
Weight (grams): 600gr
Length in front of muzzle: 140mm
Length back over the barrel 140mm
give him a ring
