FRONT BARREL ONLY!
The G2 front barrel for the Bolt is longer than our regular front barrel to accommodate the popular Pilot G2 refill. By simply swapping the front barrel and spring, you can now use another wide array of refills in your pen. We designed The Bolt to be fun to use and to be extremely durable and with this front barrel added, it may be the last pen you ever have to buy. Each pen is machined from solid material (aluminum or brass), in our shop, right here in the good ol' USA.
