The Armaspec Rhino R-23 in Gray is one of those upgrades that does its job the second you install it. It wraps around the mag well of your AR-15 and does three things at once: it funnels mags in faster, gives you a dedicated grip point up front, and helps you run the gun smoother under pressure. Armaspec built it from ultra-light, mil-spec reinforced polymer, so you're adding function without weighing the rifle down. It tips the scale at just 1.73 ounces.
The magic here is the 60-degree insertion angle. That widened funnel gives you a bigger target to slam a magazine into, which is exactly what you want when your eyes are downrange and not looking at your gun. Armaspec puts the average reduction in mag change times right around 48 percent, and folks who run these in 3-Gun and drills tend to agree the speed gain is real. Whether you're in a low-light situation or just trying to shave time off your splits, that funnel earns its keep.
Beyond the funnel, the Rhino gives you finger grooves molded into the front for a secure, repeatable hold on the mag well. That extra contact point helps you drive the gun and keep it steady, especially in close-quarters work or when you're clearing a malfunction. It's the kind of ergonomic tweak you don't think about until you've run without it.
This is a true drop-in setup with no gunsmithing and no permanent changes to your lower. It fits mil-spec M16, M4, and AR-15 lower receivers, and it handles most standard AR-15 magazines including Magpul PMAGs up through Gen 3. The two side panels clamp around the mag well and tighten down with the included set screws, so all you need is the provided hex key. Made in the USA.
It's built for mil-spec M16, M4, and AR-15 lower receivers, so as long as your lower is mil-spec it should clamp right on. It fits standard lowers without any permanent modification. Non-mil-spec or billet lowers with odd mag well dimensions may not play nice, so check your receiver spec first.
The Rhino accepts most standard AR-15 magazines, including Magpul PMAGs up through the Gen 3. The 60-degree funnel opening is what gives you that faster, more forgiving insertion. Aluminum GI mags, steel mags, and other common patterns feed through it just fine.
Not at all. This is a true drop-in design that clamps around your mag well with two side panels and tightens down using the three included set screws. Everything you need comes in the box, including the hex key, so you can have it on in a few minutes at the bench.
Almost nothing in terms of weight. The whole unit is molded from lightweight reinforced polymer and comes in at just 1.73 ounces. You get the reload speed and grip benefits without noticeably changing the balance of your build.
