Complete Upper 6mm arc Blackout defense 18"

Description

This is a complete 6mm arc upper in 18" from blackout defense. They make the sickest barrels I've ever used. Less than 5 rounds been through the barrel so this is very very new. Superlative adjustable gas block, Arca Swiss plate, CH, BCG, I'll throw in 4 15 rounder mags as well. You won't be disappointed with this upper at all. This is also a very expensive upper to buy from them directly. Text is best.
