What You Get When You Buy From Us
Real Texas Manufacturer
F-1 is not a drop-shipper. We CNC billet lowers in Spring, TX, and we test every barrel on a 100-yard range we walk to. When you buy F-1 brand parts here, they came off our floor.
Honest Stock Status
If the site says “in stock,” it’s in our hands and the label prints today. If it’s drop-shipping from a partner, the product page says so before you pay. We don’t sell vapor.
Discreet Packaging
Plain corrugated boxes, no F-1 markings outside. Receipt comes by email. We respect that what ships to your door isn’t anyone else’s business.
Real Warranty Support
If an F-1 part doesn’t perform like F-1 stamped on the side, ship it back — we’ll send a prepaid label. We honor manufacturer warranties on partner-brand parts and handle the back-and-forth ourselves.
Compliance, Not Negligence
We follow ATF and state law on every order. The cart blocks restricted items at checkout. Specialty fire-control products are reviewed by hand before they leave the shop.
A Phone That Picks Up
Call (832) 299-6101 Monday through Saturday. Real human in Spring, TX — not a Manila call center, not a chatbot pretending. We’ll talk you through any build question.
