Armaspec Rhino R-23 Features The Armaspec Rhino R-23 magwell grip and funnel is engineered specifically to speed up magazine reloads on AR15 and M4 pattern lower receivers. Its flared funnel shape guides the magazine into the well even under stress or in low light which is exactly when a fumbled reload costs the most time. Armaspec reports an average 48 percent reduction in reload times with the Rhino installed a meaningful advantage in both competitive and defensive shooting scenarios. Made from reinforced polymer the grip stands up to repeated magazine insertions without cracking or wearing down the funnel edges. Finished in Grey the Rhino R-23 attaches to standard AR15/M4 lower receivers without any permanent modification so it installs and removes cleanly if a shooter changes their mind later. The kit includes left and right side panels along with three socket head set screws and a hex key giving everything needed for a complete install in the box. At only 1.73 ounces and 4.14 inches long the grip adds negligible weight or bulk to the lower receiver. Competitive shooters and anyone running drills who wants faster more confident reloads will find the Rhino R-23 a simple effective upgrade.
