ARMS 45 C RIS flip up sights

well i found that my magul flip up sight wont work, so what will work:confused::confused: i was looking at this http://www.armsmounts.com/default.asp?mode=products&sub=sights&id=[hsh]71L-R.
Any other suggestions ?

Do you still have the parts to just put your basic handguard back on? Then you could use your Magpul sight without spending any more money.

The ARMS 40L is a great sight, and works well with that rail.

well the reason i got rid of my old rail system was because of weight and i really do not want to go back to that

thanks stick, going to put in the order now
