Builders have been adding the Battle Arms Development Engraved Ejection Dust Cover- Reaper to their builds on GunPartPicker since April 2026. All time, it ranks #27 of the 114 dust covers builders have added.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today the one retailer we track has it in stock. Prices barely moved in September 2026, holding around $16.99, so there haven't been real sales lately. Buying today, the lowest price is $16.99 at Optics Planet, which matches the best price we saw in September.
