Inner barrel alignment
 

Recently I bought a JG Dragon. The gun came with a JBU M4 KURZ suppressor. I tried the gun in my garage at 20' from the target. The gun does not shoot straight.

I rapidly found why. The inner barrel is not in the middle of the outer barrel (see picture). This is causing the bullet to hit the silencer, which creates an erratic tradgectory. After few rounds I even see now a white stripe left by the bullets on the exit of the suppressor.

I tried to find how to adjust the inner barrel to be in the middle of the outside barrel, without success. Would someone be kind enough to indicate me the procedure to perform this adjustment.

Thanks

Well there's your problem.







In all seriousness, change your hopup rubber to start.

tape the inner barrel a few wrap that should centre it

add your inner barrel plastic case to make it staight with the suppressor.

it's work for me.

+1. I did that to an old old old springer I had that had a similar problem. Works well.
