Firefly Rev

My Nerf Firefly Rev-8 doesn’t work any more after I removed the AR.?

I removed the Ar’s, no other mods, and now the gun barely fires the dart, maybe 2 inches.
And no I don’t think I lost anything.

U sure you didnt lose any peices? thats probably why? i think theres this 1 VERY IMPORTANT peice thats in every Nerf and if u lose it, then your effed
