You may want to consider one of Huang's EOTech 552 clones. Works great on this gun, and you don't need to remove the rear sight. Drop down the front sight and you're good to go. If something happens to the 552 and it stops working, pop up the front right and you can use the iron sights right through the 552 without any problem.
