Id like to get a nice looking brake for my QB78 with 16mm barrel. I know there are tons of them out there, but where to buy from? I'd like to get one about 7-8 inches long a 3/4 inch diameter, made from aluminum with a screw-in brass end cap. My QB's pcp tube and barrel is bare metal and the tube has a brass end plug. I think a nice aluminum brake with brass end cap would go perfectly with the rifle. I'd really like to have a shroud, but think the extra length would interfere with the foster fitting on the tube.
