AEA Zeus (Gen1), Challenger Standard (unshrouded), and Element Max Barrel Band Installation

Black Arts Design Barrel Bands are designed to be a snug fitting part. There are rubberized bushings in the barrel section. They are designed to allow a very close tolerance fit as well as provide some dampening effect.

It is best to have an established zero prior to installation of the barrel band. This is the only way to verify any large change in windage or elevation. There should be very little change in elevation or windage. But, if any twist was instigated upon the installation there may be a significant windage change. If this occurs see notes at end.

**MAKE SURE THE RIFLE IS IN A SAFE CONFIGURATION BEFORE BEGINNING INSTALLATION**

  1. There is a silver sharpie arrow on the inner diameter of the air tube section. This arrow must point toward the muzzle end of the rifle.
  2. Remove the thread protector from the end of the barrel to aid in getting the Barrel Band slipped over the end of the barrel. Carefully ease the barrel band over the end of the barrel using a slight rocking and twisting motion.
  3. Once the top portion is on the barrel, align the lower portion with the air tube and slide it on. Make sure the 3mm cap screw is sufficiently loosened and push it past the gold colored cap at the end of the air tube.
  4. Now the barrel band can be pushed evenly down the length of the barrel.
  5. The location is up to the user, however, it was designed to be positioned approximately 2 to 3 inches from the end of the air tube. .
  6. The barrel band is tight enough to move and hold the barrel left or right of center even before tightening it down. Try to ensure you have not instigated twisting during installation. You can slide it back and forth several inches a few times to get it re-centered.
  7. Using a 2.5mm allen key, tighten the cap head screw found on the side of the barrel band. Large amounts of torque are not needed but it should be firmly snugged up. Too much force can damage the part.
  8. You are ready to zero the rifle.

If there are large windage changes to your zero, a minor change is not significant and should be adjusted with the scope, some twisting may have been instigated upon installation. If so, loosen the 2.5 mm screw, and gently re-center the barrel. Check the zero and then tighten the barrel band. Again, check zero.
