Build history on GunPartPicker
Builders on GunPartPicker first added the SLR Rifleworks Sentry Adjustable Gas Block Set Screw to a build in July 2026.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today both retailers we track have it in stock. Prices barely moved in September 2026, holding around $141.64, so there haven't been real sales lately. Buying today, the lowest price is $141.64 at AR15 Discounts, which matches the best price we saw in September.
