If you own a Kel-Tec Sub-2000 Rifle you NEED to check out this Recall Notice... It is for “Some” 2017 and 2018 Rifles... The issue is with the barrel Heat Treating... Do NOT Fire the Weapon untill you check the Serial Number against the Recall Notice....
They heat treat them ? I always thought they they had a beaver chew them out some of those threads looked like teeth marks to me.
