The gas block is a vital component of any AR-15.  That is why it is important to get a quality piece from a reputable manufacturer, such as Troy Industries.  Troy has been part of the AR-15 industry for several years and has a reputation for excellence.  Their commitment to excellent and innovative products have made them the go to company for many AR-15 enthusiasts.


The Troy low profile gas block is designed to be installed on an AR-15 barrel with a 0.750” gas block step.  0.750” is the standard diameter for AR-15 barrels.  However, if you have a thinner, “pencil” barrel, or a thicker “bull barrel” they gas block may not be appropriate for your application.


Once in place, the low profile gas block is held by two set screws located at the 6 o’clock position of the block.  By positioning the screw screws at the bottom of the gas block, this ensures that there is a snug fit between the gas block and the gas port on the barrel to prevent gas leakage.


The Troy low profile gas block is designed to be as compact as possible.  The small size of the gas block allows it to fit under a large amount of aftermarket handguards/rail systems.


To ensure the utmost in durability and to give you a long service life, Troy machined this gas block from 4140 steel.  The steel is pre-hardened and finished with a mil-spec manganese phosphate finish.  The black finish increases wear and corrosion resistance. 


Please note that the gas tube roll pin is not included with this package.
