300 Blackout double cartridge bullet pen. Brass cartridges and gold pocket clip and copper nib tip components. The pen tip is a replica of a 30 caliber copper bullet.
Handmade in my shop, I use spent cartridges that are machined to accept standard pen components and ink refills. This is not a kit - I personally do all the machining. Spent once-fired cartridges will have slight imperfections including scratches and dings from being fired and striking the ground.
The photo showing 2 pens is for size comparison between this pen - 300 Blackout - and a 308/double cartridge pen. Only the 300 Blackout is included in this offer.
1/2 twist will extend or retract the standard Mini Cross compatible ink cartridge. Mini Cross refills are available through this website or at office supply stores.
Other calibers available. Other metal component plating colors and brass or nickel cartridges are available as well.
I've been professionally hand crafting pens for 16 years. Experience counts. Thanks for looking. I appreciate it.
