This filter kit includes a 10" premium tube, 2 endcaps, 8 filter cups and 9 springs.
This filter kit is popular for medium to large caliber rifles and carbines. A longer kit to hold more cleaning cups. Folks who use lots of ammo like these kits. Here’s some details on each part:
- Tube: 10 inch Black anodized tube made from 6061-T6 Aluminum with 2.5mm thick sidewalls to withstand heavy stress. The tube OD is 43mm, ID is 38mm.
- Attachment cap: with 13/16" center hole. 18mm (3/4”) super-thick aluminum. 6061-T6 anodized black. Takes any 13/16 fitting, fast attach, flash hider, or concussion forwarder, as long as they are 13/16" by 16 tpi (threads per inch). This is a common size of many fittings on the market. This cap screws 1/2" into the tube for a very secure grip. Adds ¼” to tube length. Our fittings & fast attach fits nicely into this attachment cap.
- Solid End Cap: with center divot. 18mm (3/4”) super-thick aluminum. 6061-T6 anodized black. Center divot will assist when drilling the end cap for a drain fitting. Cap screws ½” into tube for excellent hold under pressure. Adds ¼” to tube length.
- 8 Cups: Two stainless-steel filter cup and 6 black aluminum filter cups each have a centered mini-hole for drainage thru the filter screen. The stainless-steel cups are cold stamped from a 2mm thick sheet by a 30-ton press with template. This ensures accurate cups. They go closest to the barrel. The black aluminum cups are 3mm thick sidewalls and 7mm thick bottom. Each cup stacks firmly inside the next cup. Both the stainless-steel cup and the black aluminum cups slide perfectly into the tube.
- Fitting: includes one black steel fitting :1/2"x28 or 9/16"x28 or 5/8"x24. This is steel in this critical connection, not aluminum.
- Springs: 9 high-tensile steel springs with corrosion resistant coating. This is the exact number needed for a tight internal stack of the filter cups. The compressed springs make a coil of steel inside the aluminum tube to make the correct headspace for your cleaning rod, fluid expansion & gas expansion.
- Printed Instructions: for step by step assembly are included with your order. Suggested drill bit sizes for adding a drain are included too.
