This gas block has been updated with double gas ports for use with 45 deg and 90 deg angled gas ports.
The front port is for 45 deg barrels and the rear port is for 90 deg barrels. The AK 47 gas block combines the front sight and gas block into one assembly. We have sold thousands of these assembly's. They have proven to be very reliable under combat conditions.
The combination gas block/front sight allows the front end of the AK47/74 to be lightened up and makes the handling of the weapon noticeably more efficient. The assembly also allows the barrel length to be shortened for you guy's that want to SBR your AK's.
The front sight is adjustable for windage with a simple screwdriver. For elevation the sight post is left purposely long so that you can zero your rifle and then use the rear sight as normal.
