Frequently asked questions

Does this tool work with both .308 and 7.62mm chambers?

Yes. The Star Chamber tool accommodates both .308 Winchester and 7.62×51 NATO chambers, which share the same bore diameter. It's designed specifically for AR-platform rifles chambered in these cartridges.

Can I use this with a standard cleaning rod?

Absolutely. The Star Chamber tool threads onto standard .308 cleaning rods and works within your existing Otis or compatible cleaning system. It's a targeted accessory, not a standalone kit.

What is an FFL transfer in California?

An FFL transfer is when a federally-licensed dealer like TacticCAL receives a firearm shipped from another seller and processes California's required DROS paperwork to legally transfer it to you. TacticCAL is your gun shop Campbell in the Bay Area.
