12-Round Magazine, 2 Pack 12-Round Magazines Bullet Clips for Nerf Rival

Works just as it should, fits perfectly, functions perfectly and it's nice to see how many are left.

This is the best way to get cheap , high quality Rival and Dart magazines. I bought a few packs of 12 round Rival mags, and 6 of the 18 round Dart mags. They are very high quality and sturdy! Overall, I highly recommended them!

Verified function in a Rival Helios and a Rival Hera. Both worked fine with the Oimio magazines. The real Nerf mags have a rubberized end cap but these just use the molded clear hard plastic. Works fine. If you can get these for less than $8 each they are an OK value. A real Nerf 12 round mag can be had for $10 with 18 ammo, so that seams like perhaps a better deal.

Two off-brand magazines for the price of one of Nerf's... That's a pretty sweet deal if they work like the real thing. AND THEY DO! Apparently, springs and plastic aren't the most difficult tech to replicate because if it wasn't for the off-color orange, I wouldn't be able to tell them apart.

these work perfectly and are much cheaper than the brand name ones. We have several guns they can work in and use balls from several different suppliers, all work fine.

I tried these OIMIO magazines with two Rival guns: the Helios and the Apollo. The biggest issue is the way they were constructed. On the official Rival mags, the transparent plastic tube is injection-molded as one piece--on the OIMIO mags, they're manufactured as two half-tubes. In the attached photo you can see the joint where the two pieces snap together. That joint creates a significant convex feature that may catch in the mag well on your rival blasters. With my Helios, I had significant trouble removing the magazine after using it. The snap-together joint snags the inside of the mag well, and it requires several attempts to get it out (I don't want to force it and ruin the gun). With my Apollo, I can hear the snap-piece snagging, but it doesn't really make it hard to remove the mag. The Apollo did jam while I was using it, but I don't know that it was the mag's fault. I might've pulled the priming handle in an irregular way. After more use I'll update this review if I get more jams. I knew getting these mags was a gamble. I bought them because I got greedy and wanted more product for less money. I probably would've been better off buying the official nerf mags at 1 for $10 instead of 2 OIMIOs for $16. I can't really recommend these, because there's no telling whether you'll have mag-well jams. Best of luck. UPDATE (11/29/21): In response to a question on the product page, I also tried it with a Rival Finisher. It misfeeds at least 1/3rd of the time. For sure would not recommend with that gun.

My son bought these for himself, then had me return them because they were constantly jamming. Not sure if he got two defective ones since others here liked this product, but we returned them and are looking for something different.

When firepower matters ammo is everything. Extra rounds equal more firepower.

Used on Helios and functions well

Essential Upgrade: Clear 12-Round Nerf Magazines It's almost amusing to write a review for something as straightforward as these transparent 12-round magazines, but they're a game-changer. The standard Nerf magazines that come with blasters are orange and opaque, and most sets include only one — anyone who plays Nerf battles regularly knows how quickly you run out and how useful it is to have spares and instantly see how many darts remain. These clear magazines solve both issues perfectly. Build quality is excellent — we've had zero feeding problems, jams, or durability issues across multiple intense play sessions. If you're serious about Nerf, stocking up on these is a no-brainer. Highly recommended. 5 stars!
