Not sure if its the handquard or the barrel, but has anyone have trouble putting the knights Armament M4 MODS Rail on their 6,8SPC Upper. Ive tried and tried but seems like the top wont go all the way down, looks like its stuck on the barrel. Just want to here if anyone has similar problems and solutions. Thanks. Oh by the way i have a Stag 6.8 upper, If that makes a difference. |
