These .750″ adjustable gas blocks are suitable for the Tromix LIGHT-WEIGHT 458/375 SOCOM and 450 Bushmaster barrels.  They will NOT work with the Tromix standard Mid-Weight barrels which have .875″ gas block journals.  Standard bend profile gas tubes are used with the .750″ gas blocks, not straight tubes.  These gas blocks will fit and clear the inside of the Midwest Industries CRM hand guards used on Tromix uppers.

These gas blocks are adjusted from the front, using a six inch long 3/32″ hex key wrench supplied with the gas block.  Due to the 458 SOCOM producing nearly double the gas volume of the 5.56, these gas blocks function best in gas “Restrictor” mode rather than gas “Bypass” mode.  Great for fine tuning your bolt speed especially when running full power 458 SOCOM ammo, suppressed.  These gas blocks will fit underneath the Midwest Industries CRM 1.3″ ID hand guards.

In the event you are using a 12″ barrel with a 12.5″ hand guard, you will need the optional extended length (9″) 3/32″ hex key for adjustment.
