I recently tried to replace the stock bucking on my JG ak-47S and it wont come off.....at all!! Its frustrating because I know JG has infamous QC. Also...thats not the worst of my problems. My biggest problem is that once I put it back together again the BBs will not load into the gun. Im useing the standard High-cap mag and if I take a lone BB and place it into the hop-up well and flip the gun up-side down it will shoot. Im worried because I want to start going to an OP in April.
