Phase 5 Tactical 15 Lopro Slope Nose Free Float Quad Rail With M-LOK Black
Build history on GunPartPicker
Builders on GunPartPicker first added the Phase 5 Tactical 15 Lopro Slope Nose Free Float Quad Rail With M-LOK Black to a build in February 2026. Builds with this handguard are mostly chambered in 5.56 NATO (67%, then 300 Blackout 33%), mostly on carbine-length gas (67%, then pistol-length 33%), and nearly all AR-15.
It was in stock most days in August 2026, but today only BattleHawk Armory has it in stock. The best price crept up from $124 to $150 over August 2026. Buying today, the lowest price is $150 at BattleHawk Armory, above August's low of $124, so a better deal may come back.

Reviewed on April 18, 2026Verified with Build
Phase 5 LoPro slope nose 15 inch handguard with M-LOK has the profile I wanted - sloped at the front to clear gas systems. Free float aluminum body. Quad rail option with M-LOK slots gives versatility. Anti-rotation tabs hold position.
