Crafted from 17-4 PH stainless steel, this choke tube delivers the material strength and corrosion resistance serious upland and waterfowl hunters need, whether you're working in wet field conditions or storing your gun between seasons. Rob Roberts Gun Works reputation for quality machining means you get a tube that seats consistently and performs shot after shot.
The Raptor Mobil design reflects modern choke engineering—reliable, straightforward, and built to handle the demands of active hunting. If you run a 20 gauge and want a choke tube that won't let you down in the field, this is the kind of tool that earns its place in your gun cabinet.

This is a 20 gauge choke tube. Verify your shotgun's gauge before ordering—choke tubes are gauge-specific and won't fit other gauges.
17-4 PH stainless steel is chosen for its strength, corrosion resistance, and durability in field conditions. It's a premium material that resists rust and wear better than standard steel, making it a solid choice for hunters who use their gear regularly or in wet environments.
This choke tube is designed for 20 gauge shotguns with standard choke tube threading. If you're unsure whether your shotgun accepts removable choke tubes, consult your shotgun's manual or contact the manufacturer.
