The Aim Sports ZHMGB01 Zero Hour Micro Gas Block .750" Low Profile is a compact, minimalist upgrade for AR-pattern rifles that need reliable gas delivery under modern free-float handguards. Machined from durable 1018 steel and treated with a black phosphate finish, this micro gas block keeps weight and bulk down while maintaining a solid interface with .750" barrels.

This model is ideal for streamlined builds where clearance is tight and a traditional front sight base will not fit. Its low-profile design works well with many slim handguards, supporting range use, training, and general-purpose rifle setups that prioritize clean lines and dependable function. Aim Sports backs this design with a track record of practical, value-focused firearm accessories.
