I do not recommend for smith and wesson mp sport 2 optic ready - Sniper 2 Piece Drop In Quad Rail Handguards

Does not fit the smith and wesson mp sport 2 optic ready. This handguard is 1/16 too long to fit it correctly. Busted up my hand and my friends and to pull delta ring and no matter what it will not fit. If you insert delta ring side, the little extended picatinny(on handguard) will not allow it any farther by touching with the upper receiver picatinny. If you insert handguard towards muzzle end first, the delta ring section will seat crooked and not click in right. I do not want to waste my time chipping away the handguard by 1/16 so I will just buy a new handguard.

This handguard may work for your mp15 sport 2, but certainly not mine.
Dear, our busted up hands.
