The Phase 5 LPSN 7.5-inch Free-Float M-LOK Handguard (brand part number LPSN75MLOK) is the Lo-Pro Slope Nose update to Phase 5’s earlier quad rail design, built from feedback shooters gave the company about what a modern handguard should do better. The slender profile and longer nose section are paired with an easier installation process and a finish that goes through an extra de-burring pass for a smoother, snag-free feel in hand. It’s a strong fit for a carbine or pistol-length AR build, though Phase 5 notes that their Pigtail gas tube will not fit correctly underneath the LPSN.
