This moderator came with my AI AT when I bought it off of this forum. I haven't used it so it is just gathering dust, It's seen a couple of hundred rounds through it from the previous owner and is in good condition. I'll post some more pictures when I get a chance.
This would fit an AI AW or AI AT with a 20" threaded barrel.
£150 face to face or £150 + RFD costs to ship it.
