Instead of spending your money on MBUS sites and a new gas block, how about you do some reliability upgrades first?
- make sure your carrier keys and castle nut are well staked
- swap out the carbine buffer with an H buffer
- install a BCM bolt upgrade kit
As for optics, I'd just cut down the carry handle instead of buying new MBUS sights and I'd shy away from cheaper optics. Save up for a few more months and get the real deal from EOTech or Aimpoint (my preference).
