In this installment of the Briefing Room, we talk about a vital piece to your AR15, the gas block. Mounting and having he gas block securely fastened to the barrel is a critical step of proper rifle assembly. Sadly there are still many manufacturers and even more builders that take short cuts when securing a low profile gas block on a barrel.

Hopefully this helps you in maybe your future build or knowing what to look for when looking at rifles.
