*is a 10/22 nut*
Ok, first off I don't think those are Eagle mags. Those kits are quite old, and the Eagle mags back then, if I remember right, were clear and smoke colored. Those also don't look to be Ramline. They appear to be Condor, if I had to guess. Condor mags are notorious for having a short life span, though some people get lucky and get long lifers.
The kit itself, I have heard, has BAD accuracy and most kits need parts fitting. Nothing serious, but I have the QC is kind of bad. It may have changed, but that was just what I heard.
The kit looks nice, but I would rather make my own style kit. Then again, I also put $1200 into my first 10/22......
