You do have a good point. Rifles like the 15-22, and even the 10/22 can be problematic. They can be improved but the factory rarely gets it right. Most of the reliability issues with the two platforms are issues with the feed ramps finish, a rough/sharp throat mouth, rough chamber, and the extractor geometry.
Conversion kits and dedicated uppers can suffer from the same issues.
My cmmg went back for badly polished feed ramps. Runs great now but before it dependably failed to go to battery.
