Problem: VFC SCAR-H with a mid-cap mag inserted, on semi and auto, four to six BBs will fall, or not shoot very far (like, 10-15 feet maybe) out of my barrel. This problem is usually corrected after the first 10-20 shots out of the gun and the rest fly out flawlessly. The BBs have been Evike brand .25 and Elite Force .20 running a 9.6 NiMH and a 11.1 LiPO, respectively. Of note, the gun was worked on by AEX Sacramento while I was in Bahrain to make it a true CQB set up (yeah, yeah, spare me. I'm no mechanic). Is it possible that had something to do with it?
