Hi I have a question about the mount base. I got my ICS MP5SD6 today and I wanted to attach my mount base high-type (UTG), but it doesn't sit correctly. Now, what mount bases will fit? The owner of the shop from where I bought my ICS gun said, he also tried the TM mount bases and they also don't fit. Now, which mount bases will go? Those from ICS are too expensive, because you have to buy two pieces if you want a hi-type mount base (Sorry for my bad English) te4cup
