BBs Stuck On Lips Of Bucking. Bucking Is Puckering Too Tight On BB.

Hello everyone. I have had this same issue once a long time ago but I dont remember how I solved it.

The bbs are getting stuck on the lips themselves. All the other hop ups I have require minimal assistance from the nozzle to push the bb forward. I can push the bbs forward manually with a light tough. This hop up is choking up on the BB so much it actually requires about 2 lbs of pressure to push the bb to the bucking patch. This happens on both the stock bucking and on after market buckings.
