For discussion clarity clarity, the thumb break should push the locking bolt assembly, part 49, forward to release the barrel Any ideas what may be blocking its movement Thanks Jack  |

captjack, welcome to the forum. The top snap (#25, thumb break) should pull, not push, the locking bolt assembly (#49) rearward or retrack it away from the barrel to allow the barrel to pivot open. Since you removed the two locking bolt plunger springs (#45 & #46) you should be able to manual pull the locking bolt assembly backward to allow the barrel to pivot open. It is possible that the screw retaining the top snap sleeve (#50) which locks the top snap to the locking bolt assembly has loosened up. If it has then the top snap sleeve will not rotate when the top snap is pushed sideways. Also, if the spring-loaded rifle firing pin is not fully retracting away from the barrel breech face can make opening the barrel hard and even prevent the barrel from closing.

captjack, glad to hear that you were able to get the barrel open. I assume that the screw for the top snap sleeve was loose. When you put it back in it is advisable to use some non-permanent Loctite to ensure it does not come loose in the future, especially when shooting 357 Max. All the best.

No, I actually tried to loosen the screw previously …it is at a angle so very difficult to get a common bit in there without messing the scre up
It is very tight so I left it alone

captjack, If I remember correctly, due to the limited access I used a flathead screwdriver whose tip was bend 90 degrees to form the bottom of an "L" to loosen/tighten the top snap sleeve. screw. So, what did you find that was causing the barrel to lock up and not open?
