The Lancer Systems SIG MPX Carbon Fiber M-LOK Handguard in 14″ (brand part no. LCHMPX14) drops roughly 50% of the weight of the OEM aluminum handguard while keeping the same installation process as the factory part. Made by Lancer Systems for the SIG MPX platform, the handguard uses an M-LOK attachment system for broad compatibility with aftermarket accessories like lights, grips, and bipods. A 1.6″ inside diameter allows the handguard to run over a mounted suppressor, and on the longer lengths the extended design clears most cans for improved ergonomics during use.
