Dart Accessory: Dart Shaft Tightener 2-Pack (Total of 12)

works exactly as intended and better than an o-ring. One down side is that once you take the shaft off it'll ruin the GOMU. So you'll have to constantly buy one to replace if you plan on switching your shaft often.

They keep our l style carbon shafts snug on the barrel. We haven’t had to tighten them once since we put these on. They also screw completely under the threads so you don’t have a gap or rubber sticking out the side of your dart like traditional o rings. Highly recommend!

I used to use the rubber o-rings to keep my shafts from coming loose on from my barrels but keeping the o-rings from bulging out was a huge pain. These alleviate that issue. However, they do not work with all the barrels I have tried them on but they have worked with most. I like them and have not had to retighten any shafts I have used them on.

Keeps my shafts nice and snug. Liking them so far! First pair on, so can't do five stars yet. But, no problems so far!

If you use the O rings, try these. So much better. Iv givin some to several buddys, they have switched to these as well.

Makes a huge difference and not having my shaft loosen up. I use carbon shafts and would always have to tighten them before throwing

If you play darts you need these. They may only be a one-time-use item, but they work perfectly until you need to change the shaft on your dart.

Work ok. Not as good as o rings.... after shooting with these for a year I do like them. They are better than Owings fo sho.. I haven't broken as many carbon shafts either so not sure if it is do to theese
