Hi guys! I have had a Marauder for almost a year and a half and I rarely had the chance to use it but had a good time when I did. I really stopped using it when it began to leak air. I am sending it in to Baker Airguns to have it fixed and sent back. How do I prevent my marauder from leaking in the future? Also, the zoom adjustment knob on my scope wont move. Unless this will hamper the performance of my scope in any other way, I would rather not spend any more money on a scope. Please let me know what you think!!Thanks.
