B3 Archery Nemesis Pro Swivel — The Upgraded Single-Jaw Index Release Built for Accuracy
The B3 Archery Nemesis Pro Swivel is a roller sear, single-jaw index release with a curved trigger design and a blackened stainless-steel jaw. The Pro upgrades the standard Nemesis with a proprietary travel adjustment and a curved trigger profile that provides a more natural trigger feel and improved shot-to-shot consistency. B3's patented swivel stem connector rotates 360 degrees, adjusts to multiple length settings, and can be locked from rotating with a single set screw — making it as at home in a treestand as it is on the practice range. A straightforward, reliable release from one of archery's most trusted release manufacturers.
Key Features of the B3 Nemesis Pro Swivel
Curved Trigger Design
The Pro's curved trigger is the key upgrade over the standard Nemesis. The shape provides a more natural trigger contact point for the index finger, which translates to more consistent trigger pull and less unintentional torque at the shot.
Roller Sear Single-Jaw Mechanism
The Nemesis Pro uses a roller sear with a single blackened stainless-steel jaw. The roller sear provides a smooth, consistent break without the mechanical stacking of some competing designs. Single-jaw simplicity means fewer moving parts and reliable engagement every time.
Proprietary Travel Adjustment
The Nemesis Pro adds a proprietary travel adjustment not found on the standard Nemesis — letting you dial in exactly how much trigger movement you want before the shot breaks. Simple to adjust, and it stays where you set it.
Patented 360° Swivel Stem
B3's swivel stem connector adjusts to multiple length settings and rotates a full 360 degrees. Lock it in place with the set screw for treestand hunting, or leave it free to rotate for range work. It's a genuinely useful feature that makes the release fit more hand sizes and shooting styles without any additional hardware.
Who the Nemesis Pro Swivel Is Built For
- Bowhunters who want a clean, reliable index release with a tunable trigger
- Archers upgrading from a basic wrist strap release who want more adjustment without a complex setup
- Hunters who need a swivel stem they can lock for treestand use
- Anyone who prefers a single-jaw roller sear for its simplicity and consistency
