Just thinking out loud....

I see a subcaliber insert for a Carbine like taking a Ferrari and putting off road tires on it and using it as a rock climber. It is a poor use of a great weapon.

I have the Ruger 10/22, a very early one. I've put a nice military style sling on it like all of my rifles, Tech peep sights that look not so good but work superbly, a target hammer and slide lock and mag release that slightly extends the release. This would be the very last gun I would part with. Grab a brick and that rifle and you could eat well, protect yourself well and look cool at the same time. I don't understand why people don't think it is a close likeness of the carbine, it definitely is. Light handy, accurate and it just does not jam or FTF. It is a beautiful little tractor, easily one of the great gun designs ever made.
