Source coverage
Retailers tracked by Firearm Data Lab
Coverage is source-by-source. Some retailers expose clean feeds, some need browser-backed listing checks, and some prices require source-specific parsing.
Current source mix
The tracker currently includes Palmetto State Armory, Brownells, Bereli, MidwayUSA, Primary Arms, Etowah Firearms, and GrabAGun. Coverage depth varies by retailer and category as each source is validated for price, stock, URL, and category quality.
Why prices may differ by retailer
Retailers expose sale, MAP, cart-only, family-page, and variant prices in different ways. Firearm Data Lab uses source-aware parsers and spot checks to avoid treating a neighboring variant or display-only MSRP as the real current price.
Human review matters
New sources are sampled before broad trust. Staff review pages flag suspicious rows, source anomalies, risky deals, missing ammo parses, and dead retailer destinations so data quality can improve over time.
