Shot my new 10/22 for the first time and was dissapointed with how difficult it was to release the charging handle. I held the release button and could not get it to release several times. I wound up having to pull the magazine out turn the gun upside down and stick a finger in and wiggle the bolt to get it to release. seems to me like something is not lined up propperly. This was a brand new gun out of the box. any ideas.
