Finally my SD chamber arrived from HK.maybe some of you guys remember that i have problem with guarder chamber,so i order a SD chamber to replace the guarder one.
but i have a problem with the SD chamber as well.dunno why but the hopup chamber to SD chamber fitting is wayyy too tight (around the area where SD rounds the corners).so i filed those area in the SD chamber just enough so that the hopup unit can be inserted and move forward and backward (as it should be able to).
The problem is that after i screw the outer barrel to the chamber,the hopup can’t move back and forth, it stuck. But if i unscrew it halfway/or just even a few turns, it can moves again just fine.
i noticed that even though the inner barrel aligns perfectly with the hopup unit, if i insert it to the chamber it looks as if the inner barrel is tilted a bit to the right.(looking from the end of the inner barrel/bb exit, chamber markings side up).and maybe if i attach the outer barrel, the inner barrel is not aligning properly with the outer thus creating the problem.
I’m afraid to file anything since gbb parts (especially metal parts) are kinda hard to get by here in indonesia.thanks alot.
