Prime introduced its latest flagship hunting bow today — the 2023 REVEX. The company’s engineering team set out to design a rig that would prove ultra-stable, smooth drawing, mechanically efficient, rock solid on the target and down range deadly accurate.
To that end Prime outfits their new REVEX with Center-Grip and Swerve riser technologies, wide-stance and offset split limbs and limb pockets, the new modular Core Cam, Nano Grip, a new String Stop and much more
The REVEX-machined 82X aluminum riser is built specifically to bring greater stability through the company’s Center Grip Riser design and integrated Swerve feature. By placing the grip in the center of the bow — as opposed to rigs that center the anticipated nocking point — a portion of the mass weight is shifted lower, which acts like a built-in stabilizer and enhances stability and improves aiming. The top cam is slightly larger than the lower cam to compensate for the offset nock travel.
Prime’s popular Swerve Riser Technology is back for 2023 and featured on the REVEX, bringing balance through a harmonized structure both above and below the grip. Swerve, which is the actual structural section on the bottom half of the riser, is designed to mimic the sight window structure in terms of movement and flex. The intent is to control lateral movement of the cams during the draw and shot cycles resulting in less movement and greater consistency. To prove their design, Prime physically measured and found lateral cam movement was reduced by 50 percent with their Swerve.
As with most bowhunting rigs, the REVEX has what is known as a reflexed riser, which places the pivot point of the limbs in front of the throat of the grip. With all else being equal, a reflex bow will have a longer power stroke, shorter brace height, and in turn will generate faster arrow speeds. For 2023, the company also built their new riser with smaller cutouts to add strength and stiffness to the platform. Stiffness in the bow riser is said to bring enhanced consistency. Also new this year is a rear stabilizer bushing for mounting back bars.
Prime’s Nano Grip uses NASA-developed Aerogel which serves as a buffer between the riser and plastic overmold grip, blocking the cold temperature of the metal from transferring into the grip. The result? Warmer hands in colder temps. The shape, angle and contour of the Nano grip is designed to produce a neutral wrist position.
A flexible mounting arm teams up with a set of rollers to create the Flexis-AR cable management system. While drawing the arm bends toward the bow’s centerline and then quickly moves back and out of the way when the bow is shot to allow vanes pass untouched.
Accuracy At Its CORE
Prime’s new Core Cam puts the company’s Cam Balancing Technology to work. This system brings the cables and string in line with each other during the draw cycle, which keeps the cams balanced and actively works to reduce cam lean. The Core cam is modular to produce the absolute best performance possible at every draw length. Modules have cable stops built in. Said to demonstrate their smoothest draw cycle to date the Core cam uses a string, power cable and take-up cable, all anchored exclusively to the cams, which is similar to a 3-track binary system. Prime, however, designed the cable grooves to shift the take-up cable over top of the axle’s center and in line with the string to focus the lion’s share of the force on the centerline. The resulting balanced load attacks efficiency, consistency and accuracy-robbing cam lean. Draw lengths range from 26.5 inches to 30.5 inches and letoff is set to 83 percent.
There are many features and technologies on the new Prime REVEX that work to tame the shot. First is the past-parallel position of the split limbs at full draw. This configuration forces energy from the shot in equal and opposite directions, effectively canceling each other out and producing the well-known benefits of reduced vibration, shock and noise. Another note about limbs and limb pockets; a close look at the machined aluminum limb pocket reveals a position just off center. Working with the Core Cam System this shifts the cables toward center while also maintaining the 7/8-inch center shot, typically found on the Company’s bow designs. The short and stout limbs that are set far apart to enhance stability through torsional rigidity. Limbs are available in peak draw weights of 40, 50, 60, 65, 70 and 80 pounds.
Prime also introduces an all-new carbon weave string stop that is said to improve on shock and vibration dampening over past models. The soft rubber stop quickly reduces string oscillation after the shot. Additionally, Prime places two of their Integrated Riser dampeners at the lowest point of the riser on either side of the lower limb bolt. The dampeners each have three weighted extremities that absorb vibration as they move during the shot. A weighted rubber wrap on the Flexis AR arm serves the same function. Last but not least, each set of machined split limbs are outfitted with the Company’s Split Limb Dampeners to kill any left over energy channeled through each limb piece.
Prime has partnered with TightSpot to design a quiver built specifically to fit the REVEX like a glove. A special Prime bracket is used to mount the Prime Shift-Lok quiver directly to the riser. Another partnership was formed with Hamskea Archery Solutions to design a new limb driven arrow rest — the Prime Epsilon Rest.
Test Range Notes
- Motionless at full draw — rock solid on the bullseye.
- Quick pause followed by the top of the bow slowly falling away after shot.
- Almost no detectable vibration.
- Medium “jump” in the handle.
- Comfortable and functional grip — no unwanted pressure points.
- Draw was consistent beginning to end — stout!
- Noise level was good — better than average.
