Amend2 Priapus Pistol Grip For AR 15 AR 10 Polymer Construction Black Vertical Grip Angle PPGBLK AMPPGBLK UPC 749355071593
Product Description
The Amend2® Priapus Vertical Pistol Grip (SKU: PPGBLK / UPC: 749355071593) redefines shooter ergonomics for modern short-barreled rifles (SBRs), AR pistols, and long-range precision rifle chassis systems. Traditional 25-degree A2 pistol grips force unnatural ulnar wrist deviation when shooting with collapsed stocks or from prone precision positions; the Amend2 Priapus corrects this biomechanical strain with a true vertical grip angle that aligns the shooter's wrist, forearm, and trigger finger directly inline with the bore axis.
Injection-molded in the USA from high-impact, fiberglass-reinforced nylon polymer, the Priapus grip withstands extreme mechanical shock, sub-zero temperatures, and harsh gunsmithing solvents without cracking or deforming. Its contoured palm swell fills the firing hand naturally to eliminate fatigue during extended range sessions, while deep horizontal frontstrap and backstrap ribs combine with aggressively textured side panels to lock the rifle into wet, muddy, or gloved hands.
Weighing just 2.88 ounces, the Amend2 Priapus mounts directly to any standard AR-15 or AR-10 lower receiver grip tang and properly retains the safety selector detent spring on standard lower receivers. Whether dialing in a 90-degree vertical trigger press on a PRS competition chassis or maximizing CQB weapon control on a compact PDW build, the Priapus delivers unshakable retention and repeatable trigger finger placement.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Fits Mil-Spec AR-15, M4, AR-10 / SR-25 / LR-308 lower receivers, and bolt-action rifle chassis accepting standard non-beavertail or standard-tang AR-15 grips. CRITICAL HARDWARE WARNING: The 1/4"-28 mounting screw, lock washer, and hex/flathead driver are NOT included by Amend2 with SKU PPGBLK. Ensure you retain your existing AR grip screw or source a standard 1/4"-28 x 1" grip screw prior to installation. Torque to 35–40 in-lbs with blue threadlocker; do not over-torque or let the screw protrude into the receiver trigger pocket.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty before placing the weapon on safe.
- Place the lower receiver upside down on a padded armorer block, remove the existing pistol grip (if applicable), and carefully retain the small safety selector detent and selector detent spring housed inside the right side of the receiver tang.
- Verify the selector detent pin rests point-first inside the receiver channel, align the top spring blind hole of the Amend2 Priapus grip over the protruding selector detent spring, and slide the grip straight down onto the receiver tang without kinking the spring.
- Insert your user-supplied 1/4"-28 AR grip screw and star lock washer through the bottom cavity of the Priapus grip, apply a drop of medium-strength (Blue 242) threadlocker, and tighten to 35–40 in-lbs.
- Perform a complete mechanical function test by cycling the safety selector between SAFE and FIRE to verify crisp, positive detent clicks and unobstructed trigger movement.
