Loaded Chamber

This upper in 6mm ARC had a combo block made out of a Superlative Arms piston conversion adjustable gas block and an A2 front sight. The A2 gas system and rear ring were cut and machined off. The rear of the sight was milled to fit the Superlative gas block and positioned where it would be on a standard A2 sight. The block and sight were welded and blended. The front of the A2 sight post was milled to allow gas adjustment and piston removal. The rail was machined for the new combo block. The block and barrel were coated in Graphite Black Cerakote.
