When purchasing Faxon Firearms or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

These ultra-low profile gas blocks are perfect for use with any rail system and are an ideal companion for barrels from Faxon Firearms or any other brand featuring standard diameter gas journals. Constructed from high-strength steel, all Faxon gas blocks are designed with a matching black luster to that of their barrels.

For lightweight builds, the block features a drill through the middle of the profile, and the gas block clamps on to the barrel with the assistance of 3 allen keys located on the bottom of the block.

To ensure optimal performance, Faxon Firearms recommends using a thread-locking compound, such as Loc-Tite or similar, as gas blocks tend to get extremely hot. The choice of compound should depend on your intended use of the firearm.
