Secret

Hi all, I've had my MWS for a little over a year now and for some reason having issues with the cold this weekend. It's about 10 degrees C and I could only get through about 5 shots before the bolt was REALLY sluggish. It would chug through the last 30 (if it made it) and then be completely out. I've not done the gas mod and I was using Nuprol 3.0, stock buffer, bolt, nozzle etc.

Hi all, I just got a TM MP7 which shoots beautifully but I want to run heavier bb's- 0.3g and the stock bucking can't do it. I had a spare ML 60 degree bucking, I can't remember what one exactly, I think the autobot, which I tried putting in, but can't seem to hop the 0.3s. I'm using the standard barrel and nub so I'm not sure if this is where I'm going wrong (maybe window on barrel is too short) or if I must have installed it incorrectly. Any help with anyone else's experience with this would be greatly appreciated!! I'm using green gas, not sure of the fps as I don't have a chrono Thanks
