Review on CUESOUL Koff AK6 Dart Stem/Shaft with Dart Flight Standard/Teardrop/Kite Set - Pack of 3 by Russell Ross

I really like this product. Worked great with most of my dart barrels. However, it didn't work well with my cuesoul barrels. It was disappointing. The stock was not fully seated in the barrel and when I pulled it back to see what happened I noticed that it was depressing the spring and lifted it. I would say the barrel just wasn't machined deep enough to accommodate the shaft with this spring. However, they are both Cuesoul products. Another thing that disappointed me is that I got two different shaft lengths. I double checked my order to make sure I didn't make a mistake with the order. My order says I ordered both of the same length.
