NERF Mega XL Dart Refill, Includes 10 Mega XL Whistler Darts, Largest Mega Darts Ever, Makes Whistling Sound When Fired

Only CON is that there isnt a pack with a higher quantity. Fun to hear them whistle in the air but a bit embarrassing to be hit by them because they should too be easy to dodge.

Work just like the originals

this is a good waty to get some mega xl ammo. the ammo whistles and its being used now in my big rig

I bought mine for aerial bombs for my R.C. plane...they whistle great coming down.

Kids love Nerf stuff

Made a grandchild happy

Based on the giant size I sort of expected these to be a bit flimsy. This is not the case! They’re heavy duty and pack a punch when they hit.

We use these blue ones in the Nerf Mega XL. The kids love them. Like launching artillery rounds. They whistle when they get close.

I personally picked these up for use with my old 98 Big Bad Bow and bow do they work well with the blaster. 50+ feet easily currently unable to fully test things as its freezing outside and thus I am unable to go out there for a while and put these through its possible paces. But from what I have gathered from using them in a narrow hallway they fly plenty straight and even whistle when shot off the stock barrel of my Big Bad Bow which has NOT been modified in anyway so the stock spring is working perfectly as well.

Huge!
