Very easy to install. Comes with a front sight tool, in case you do not have one. Front sight installed very quickly. Rear took some time (using MAGPUL MBUS flip-up). They do not fit the rear Magpul screw dial, plumbers tape can fix that. Front green very easy to see, Orange takes some concentration. Good for no-light situations.
Pros: Easy to install
Cons: Orange not too bright
