/k/ 

The "Weapons" board of 4chan.
A regular poster on /k/ is usually referred to as a /k/ommando, and discussions usually involve modern weaponry, but this is by no means exclusive.
Like most other boards on the site, it is primarily likened to a river of shit with gold nuggets on the bottom. Whether or not it is worth panning is entirely up to you.

/k/ - a magical place

/k/ is the weapons board of 4chan. People from around the internet post pictures and have discussions about guns, knives, swords, and other military things like camouflage and vehicles. There are also cool stories of gun users and sometimes there are gun range meetups.

I went to /k/ today and found some cool pictures of guns.
