I have a G&G M4 CQB-R and I recently purchased and installed a Daniel Defense Omega rail. However it doesn't fit as nicely as I wanted it to, the top rail isn't flush with the body and there's a weird gap where there shouldn't be. I'm looking to get a rail system that will give my gun the look similar to a HK M416, where the rail system is flush with the body and the rail is continuous from beginning to end. Can anyone help me out?
Here's a picture of my gun with the Omega rail system, you can notice the gap.
