Questions & Answers
is this the 300 Blackout handguard? i currently have the 5.56 handguard and i need the 300 blackout handguard to convert it. Expert Answer

This SIG SAUER Mcx Rattler Low Profile M-lok Handguard is the 5.56 model. Standard MCX handguards are not compatible with Rattler models and this handguard is not compatible with the 300BLK Rattler. Those handguards are listed separately on Sig Sauers site.
