The Rob Roberts TSS Raptor Choke Tube (brand part no. 200307) is a 12-gauge wing-shooting choke built for the Mobil thread system and tuned to deliver optimal performance with premium tungsten super shot loads. Rob Roberts Gun Works machines the TSS Raptor from 17-4 PH U.S. stainless steel, a strong addition to the RRaptor series born from years of patterning development. Tungsten shot patterns differently than lead or steel, and this choke’s geometry is matched to get the most from those dense, expensive pellets. Among shotgun chokes, the TSS Raptor favors turkey and waterfowl hunters running TSS loads through Mobil-threaded barrels.

Frequently Asked Questions

What is a TSS choke? A choke with internal geometry tuned for tungsten super shot, which is denser than lead and patterns tighter, so the choke is matched to take full advantage of it.

What barrels does it fit? Shotgun barrels threaded for the Mobil choke system.

Can I use it in both barrels of an over/under? No, the manufacturer specifies one RRaptor choke per over/under; the design does not allow both barrels.
