Quad Rail vs M-Lok AR15? #shorts
This guide compares the Daniel Defense RIS II quad rail and RIS III M-Lok handguards for the AR-15 platform. The RIS II is the classic 'cheese grater' with Picatinny rails, while the RIS III offers M-Lok slots with a similar robust build and weight. The comparison highlights that M-Lok on the RIS III doesn't necessarily mean a lighter handguard compared to its quad rail predecessor.
