This kit includes a 8 &3/4" tube with 2 endcaps: one solid encap with center divot and one 5/8 x 24 endcap. Inside the tube is 8 (eight) cone cups made of 7075 aluminum. The cone is 60 degrees, 1 & 1/2" wide and each cup has a lock rim to connect tightly into the next cup. These 8 cups fit perfectly into the tube from endcap to endcap, so there is no headspace room and no spacer. Usually, this could be tricky to use except this kit is 1 & 3/4" wide (OD) which make the tube a healthy size and the cups a healthy size too (D size cups).
Some folks like this setup for solvent storage, some folks like to drill the cups for solvent filtering. This kit is an attractive addition to your gun maintenance collection.
PS-we only have the complete kits at this time, no extra parts to sell. The individual parts on the webstore (38mm/1.75") do not fit this kit.
