My krytac shoots two bbs in semi as if it were in a two round burst mode just bought a krytac mk2 crb. I had maybe shot 10 bbs out of it before having evike replace the small Tamiya plug with Deans. I’m running a 11.1 20c Lipo. It’s the 350 fps version so maybe the spring is too weak? I haven’t been into airsoft for maybe 7-8 years any help would be appreciated.
