Laylax EG Barrel Wide-Expanded HOP Window 6.03mm Inner Barrel

The Laylax EG Barrel Wide-Expanded HOP Window 6.03mm Inner Barrel is a new type of inner barrel produced by Laylax. It has a wide expanded HOP window. This means it is compatible with more HOP nubs and tensioners, allowing for more setups, including things like R-HOP and other extended HOP tuning techniques. It comes in a choice of lengths, perfect for most standard M4 builds with 11", 12" and 14.5" handguards. This barrel is compatible with V2 gearbox TM-compatible assault rifles; it will not work with NGRS or M14 platforms. Its stainless steel construction makes it far more rigid and less prone to bends than other brass and aluminium barrels.
