Build history on GunPartPicker
Builders have been adding the B5 Systems Modular Picatinny Stock to their builds on GunPartPicker since April 2026. All time, it ranks #205 of the 463 stocks and braces 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 $190, so there haven't been real sales lately. Buying today, the lowest price is $190 at Primary Arms, which matches the best price we saw in September.
