S&J Hardware AR-15 Low Profile Gas Block

$55.00 USD

The main issue with many aftermarket gas blocks is that they are too thin and when the gun is hot, tend to leak  gas, resulting in a higher chance of issues. But an overly large gas block will not fit under many free float railed forends.

Our low profile gas block is strong enough  to work with full auto carbines and small enough to work with many of the ultra low profile rails such as KAC, Larue and Daniel Defense.


  • CNC machined 4140
