I’m wondering if anyone out there has a Daisy Power Line 922 or maybe even the Daisy 22SG. I have the 922 and the 880 in .177 caliber, and the 880 has a small o-ring on the magnetic tip at the end of the bolt. I’ve noticed that the 922 doesn’t have this same o-ring, or at least mine doesn’t. While shooting it today I noticed that when I place my finger near the loading port I can indeed feel a puff of air when the shot is taken. I have run my 922 through the chronograph and it is hitting about 550 fps with CPHPs. I’m just wondering if I mine is missing something. I purchased the gun used and it was in great shape so I don’t thing it is missing anything but I thought I would still ask. I’ve also checked the parts diagram for this rifle but it is of extremely poor quality and I don’t see any part or part number for what I see on the Power Line 880.
