Problem with removing barrel from receiver

[SXS OHIO]

I just had this issue. The reason the gun would not release the barrel hook to remove the barrels. I think from sitting i a heated safe for extended periods the lube or oils dried up and froze two moving parts. The for end indicator shaft that protrudes out of the receiver was stuck in and the slider mounted to the belly plate was also not moving. SEE PICS This was an easy fix but correct screw drivers are a must and may need hand fitted to the screws slots so not to booger them up! SXS Ohio
