The Icarus Precision ACE magwell is a machined aluminum upgrade built for shooters running the Ruger Rxm and Zev Oz9 platforms with Icarus ACE grip modules. It widens and funnels the magazine opening so reloads drop in faster and seat more consistently under pressure. This is a part aimed at competitors and anyone who wants to shave time off a reload without changing the way the pistol carries. Note one thing up front: it fits the Icarus ACE grip modules, not the factory stock Ruger Rxm grip module. Pair it with the right module and it bolts on clean.
Construction is aluminum with a black anodized finish, which holds up to the abuse a competition or duty gun sees in a season. The funnel profile flares at the base to guide the magazine into the well, cutting down on fumbled reloads when your eyes are on the target instead of the grip. Icarus machines the part for a tight, wobble-free fit against the matching ACE grip module, so there's no slop where the magwell meets the frame. The streamlined shape keeps weight down without thinning the walls at the stress points. It's a focused, single-purpose upgrade that does one job well, and it pulls double duty across both the Ruger Rxm and Zev Oz9 once the ACE module is in place.
Most buyers reach for this when they're building out a match gun and want a cleaner, faster reload than the stock opening allows. It also makes sense on a defensive or duty pistol where a missed magazine seat is a real problem. Run it alongside an extended magazine release or base pad extensions to round out a reload-focused build, and browse our full lineup of magwells and magazine extensions to match parts to your frame.

No. The Icarus Precision ACE magwell is built to fit the Icarus ACE grip modules for the Ruger Rxm and Zev Oz9. It is not compatible with the factory stock Ruger Rxm grip module. You need the matching ACE grip module installed for this part to fit correctly.
It's machined from aluminum with a black anodized finish. The flared funnel at the base guides the magazine into the well, and the precision machining gives a tight fit against the ACE grip module with no wobble.
Yes, as long as the pistol is running an Icarus ACE grip module. The same magwell is designed to fit both the Ruger Rxm ACE and Zev Oz9 ACE grip modules, so one part covers both platforms once the correct module is in place.
The wider, funneled opening steers the magazine into the grip so it seats on the first attempt more often. That cuts fumbled reloads under stress, which is why competitors and duty shooters add them to reload-focused builds.
