The Q QSERT Handguard (brand part no. ACC-FIX-HG-QSERT-15) is a 15 inch handguard purpose-built for The Fix by Q, using Q’s own Q SERT mounting solution rather than a generic clamp-on interface. Because it is engineered specifically around the Q SERT mount, it keeps a slim, free-float profile with no added bulk at the receiver. Shooters running The Fix who want a longer rail for lights, optics offset mounts, or forward grips get a factory-matched fit rather than a universal adapter. It is a straightforward, purpose-made upgrade for an already purpose-built rifle.

• Purpose-built for The Fix by Q, ensuring a factory-matched fit rather than a universal clamp-on.
