"We like to stack'em deep and sell'em cheap, so you can expect to find great prices on all the things you need."

This isn't a boutique operation. Centerfire moves volume—they maintain deep inventory across every major platform and ammunition type. Prices reflect that volume model. They're a resource for shooters who know what they want and need it fast.

For the builder crowd, they stock individual components: bolts, bolt carrier groups, barrels, handguards, buttstocks, fire control parts, muzzle brakes, gas tubes, springs, pins, and detents. They also carry build tools specific to AK, AR, and SKS platforms.

ProMag, Glock, and many others in stock. They rotate inventory constantly, with a separate "New Arrivals" and "Bestsellers" section updated regularly.
