12ラウンドマガジン、4パックラウンドマガジン弾丸クリップ ナーフライバル用

The spring in the magazine would constantly push out ammo. I loaded a magazine completely and watched as it ejected almost half of the ammo I put into it. Buyer Beware

They're alright and work well in every regard except for when you carry them loaded outside of a blaster. The catch at the top just doesn't hold the balls in that well. Get these if you're handy and have a 3D printer so you can design and print a catch that works, but I wouldn't consider these as a good choice for actually playing with.

Spring could be stronger, but is a great replacement and a cheaper option to nerf brand

I purchased these for the new Pathfinder. I tested tubes with out of the box new Blue Rival ammo and out of the box new blaster. They do not feed properly the retention mechanism is poorly made and gets stuck when the rounds are loaded not chambering the round. I bought 8 and not a single one functions the springs are too weak to beat the friction of the round in the tube. Just buy Nerf Brand for clipqzines

At $5.25/unit I had to give it a try. As others have stated the combination of release mechanism and spring length/strength resulted in the the clips not maintaining the 12 rounds if fuly loaded, often unloading about half of the clip because of the release acceleration. By slightly modifying the clips I found great success with them holding a full load of rounds for more than a day. Mileage might still very based on ammo tolerance; I found that the 3rd party ammo seemed a tad smaller and 'more slippery' than official Nerf ammo, causing it to be more likely to discharge as well. My modifications were shortening the springs by about an inch. In the photo the one on the left was a bit too much, middle was just right, and the one on the right I ended up taking a bit more off of. I also slightly melted the side OPPOSITE the release mechanism to make the hole slightly smaller. That was BY FAR the most effective way to improve the ammo retention. The clips worked fine with the Rival Challenger and Rival Mirage, but notably the clips are inserted reverse of each other, a bit confusing for younger users. I did experience a few jams with the Mirage, but I believe that was more associated with the design of the mirage than the reduced spring strength of the clips. This only occured on the final round of the clip, and arguably a 12 round clip is a bit much for that weapon anyways, but should still be noted. Overall at ~$5 a clip, it was very easy to modify them to be well working for my needs, and I would do it again if I needed more. It would be nice if they worked from purchase, and I don't know how durable my modifications will be long term, but still worth it to me.
