Good morning, Phil.In November, 2023, I received a Stormrider Synthetic .22 that would not shoot. I received the rifle on a Saturday and could not talk with anyone at Pyramyd Air. On the following Monday, I got the information I needed to return the rifle and shipped it UPS. On December 1, 2023 the replacement rifle arrived. I don't remember the date in November I received the first rifle. So, I am going to answer your question about 'turn around time' by saying: It will likely take about three weeks for you to receive the replacement.
PhilWhen you started post on PA - I thought you had dealt with them before and Avator's reply#2 was about returning to PA.https://www.gatewaytoairguns.org/GTA/index.php?topic=212584.0Getting the spring out is easy but I do not know how difficult it is to get hammer out without watching You Tube on it.Good luck.
