Spring kit?

[Brad in Idaho]

Took my granddaughter to the range Sunday. She likes shooting the carbines. The Rockola I took is a good shooter, but it started failing to go into full battery occasionally. Had to tap the bolt forward to be sure. It was clean, so I don't think that was the problem. I'm thinking just old age of springs? Where is a good source of springs and which ones would most likely need replacement? Thanks.

Old age usually doesn't bother springs. Over use will cause them to lose their "spring". With the carbine unloaded you should be able to tell if the bolt group goes forward with enough force to lock up. The recoil spring is cheap and an easy fix, and would be the first thing I tried.
