No. The A2 front sight on the Sport also serves as the gas block and secures the handguard. You would have to replace it with a gas block similar to what's on the Optics Ready or replace the handguard with a freefloat and low profile gas block.

If your overriding concern is the A2 front sight I would suggest looking at rifles with free float handguard and also longer in length to better accommodate the light you want to mount and anything else.
