Builders have added it to their builds on GunPartPicker. Since April 2026, it ranks #72 of the 2,068 upper receivers builders have added.

Availability is good: it was in stock at one retailer or another nearly every time we checked in October 2026, but today only Optics Planet has it in stock. It dipped to $264.42 at BattleHawk Armory for a stretch in October 2026, well under its usual $294.52, so sales do come around. Buying today, the lowest price is $288.99 at Optics Planet, above October's low of $264.42, so a better deal may come back.
