Arsenal RZR MAG3: The XL Platform That Refuses to Punish Your Back
Here's the deal most saddle hunters already know too well: the bigger the platform, the heavier the pack, the shorter the hike you're willing to make. It's been the dirty trade-off of mobile hunting since the first guy bolted two boards to a tree and called it a stand. Arsenal's new RZR MAG3 is a direct swing at that problem — and it connects.
Why Platform Size Actually Matters
Spend eight hours in a saddle during the November rut and you'll understand real fast that foot room is not a luxury. Shifting your stance, pivoting for a shot angle, peeling a leg when the circulation cuts out — all of that needs real estate under your boots. The trouble is, most XL platforms in this category push five pounds or more before you even clip your sticks on. That's a brutal number when you're three miles deep on public land.
The MAG3 is a direct response to Arsenal customers demanding an even larger platform over the previous-generation RZR MAG. They listened, and then they went to work with the CNC machine.
The Specs Worth Talking About
Arsenal pushed the overall width out to 16 inches and a 14-inch depth from front edge to back teeth, giving loads of clearance off the tree. That's a serious chunk of real estate — comparable to some hang-on stands — wrapped up in a saddle platform footprint.
The weight is where things get interesting. Despite its oversized footprint, the MAG3 weighs a mere 3.5 pounds while many competitors' platforms in this size category are pushing 5 or even 6 pounds. That's not a rounding error — that's nearly two pounds of advantage before you've even laced your boots.
The platform is CNC-machined from high-strength 7075 aluminum, allowing Arsenal to slim down the design without sacrificing strength or stability. Like all platforms in the RZR line, the MAG3 is incredibly slim, nesting down flush into an ultra-thin 1.5-inch profile. Slide it in your pack flat and it disappears. That alone is worth talking about.
How It Actually Hunts
The front edge incorporates a wide 3.65-inch, 15-degree taper providing excellent foot support if you prefer an aggressive leaning position. That taper is subtle but you feel it during a long sit — it takes pressure off your toes and lets you settle into a lean without cramping up after hour three.
Aggressive tree engagement teeth deliver stable platform bite with minimal shift under load, and noise-dampening bumpers reduce contact noise during transport and setup. On a quiet October morning, those bumpers matter. Nothing kills a hunt faster than metal clanking against aluminum while you're trying to dial in silently at first light.
The platform isn't completely flat — a slight slope helps reduce foot fatigue and encourages a more natural stance, a smart middle ground between traditional flat decks and fully angled designs. It won't replace a dedicated angled platform for hunters who love that style, but most guys will find it a non-issue after a few sits.
Who Should Run This Thing
Straight talk: if you're an ounce-counter running ultralight sticks and a sub-pound saddle on a quarter-mile walk-in, the MAG3 probably isn't your platform. It is still an XL platform — meaning it will never disappear on your pack like a micro platform would. Hunters who prefer a truly minimalist setup may still view it as more platform than they need.
But if you're punching deep into good timber, setting up for all-day November sits, or if you're just a bigger guy who has been squeezing onto undersized decks and paying for it in hip flexors — this is the move. If you've been reluctant to move into the large-platform category because of weight concerns, the RZR MAG3 is one of the easiest transitions available today. It delivers space where it counts without demanding a full commitment to the heavyweight class.
The mobile saddle hunting world has long defaulted to smaller is better as gospel. Arsenal is making the case that smarter is better — and the MAG3 is a pretty compelling sermon. Send it.
