Hello. So im new, anyway. I own an lm4 and have been using it for about 10 months and once every month i play with it only green gas, never propane hurts my nose, and .25 or .28 bbs. Now on AUgust 31st i flew to Florida for vacation played all day with my lm4 no problem. I went home cleaned it and oiled and put it away. IN beginning of December i went  lubed it again as it was dry and then headed out to play. With every mag i own the 2nd shot would jam. If i shot with 2 second intervals between each shot it would be fine, but shooting at a faster rate it would jam every time 2nd shot. The gun would act normal too no hiccups in the trigger. When i would pull back the bolt after a jam one bb would still be in the hop up and the second in trying to get loaded or cracked or stuck to the nozzle. Im not sure what it is because nothing looks broken and it rain perfectly last time i used it three months ago and im only using green gas so i cant even blame it on anything else. Im confused anyone with experience on this might happen or how the gun works let me know what to do. I can answer questions and post pictures to help too. THANKS!
