Build history on GunPartPicker
Availability is good: it was in stock at one retailer or another nearly every time we checked in October 2026, but today only BattleHawk Armory has it in stock. It dipped to $140 at Optics Planet for a stretch in October 2026, under its usual $150, so sales do come around. Buying today, the lowest price is $150 at BattleHawk Armory, above October's low of $140, so a better deal may come back.

Reviewed on April 18, 2026
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.
