Clamp-On Magwell Funnel to get your Rifle 3-Gun Ready with Fast Mag Changes

Sometimes, the best solutions are the simplest.  For faster reloads under pressure, the R-23 Rhino Magwell funnel is the easiest way to do it.  This is a true drop-in solution, with no special tools needed to install.  In addition to increasing the area for magazine insertion, the R-23 also has finger grooves for a quick, secure grip on the magwell.

Faster Reloads

  • Compatible with all types of AR15 magazines, this adapter quickly and effectively funnels magazines into your lower receiver with a large margin of error

Simple Installation

  • Using the included allen wrench, simply back off the three bolts of the assembly and snap it onto your mil-spec lower.
  • Seriously.  Nothing goes inside the trigger guard, and no removal or dissasembly is necessary.

Cost Effective

  • You don’t need to invest in an expensive, specialty lower to enjoy the speed and functionality of a flared magwell.  Snap on the Rhino and you’re ready to rock.

Funnel your mag

It definitely helps feed the magazine, but it is a little large for what it does.

Jorge L Montero
Nice Grip

First time in a long time, I can put my hand close to the magwell. It's feels solid and comfortable. Thanks

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Installing is straight forward and comes with what you need. The magwell/grip is quite large and a 5 round magazine disappears inside of it. In use it disappears. I would buy again, and I did.

Like a glove

Ordered the R23 for my psa multi lower. Fit like a glove. No gaps no cracks no wiggle. Outstanding right out of the box. Had it on my rifle in seconds.
Accepts all 30rd mags I have. A bit snug on my straight 60rd mag, easy fix.
Great product. Shipped quick. Direct fit. No flaws. Functions exactly for what I bought it for.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!
