They work as advertised. (Along with the other barrels I have.)
Now I just have to decide what my favorite combinations are...
Both of the new barrels I used worked great! Triple Mega has a nice tight spread with great distance when paired with the mighty mama. Mega XL works great and also fires standard elite and short darts. Amazing design work on these and amazing print quality!!! Perfect in every way!!!
The Mighty Mama is a fantastic little mounted blaster, I got mine with all the large barrels and swapping between them is a ton of fun. The triple mega barrel is a bit finicky and definitely prefers mega accustrike rounds, but the Mega XL/short dart barrel combo is PERFECT, and the 5 elite darts is fun, but 10 short darts is way funner
