The Sport is an entry level gun.
I have owned Deltin and think they are a good value.
But it all depends on the price.
The Sport is their entry level comparable to the S&W 15 Sport.
I think its perfectly suitable to plinking and self defense.
I would only advise against it if you are a security contractor going to the middle east need it as a professional tool.
Basically in todays market you buy the AR thats a) available and b) affordable
Sometimes I wonder:
We spend SO MUCH money on guns to have redudancy "just in case" they get outlawed.
We spend SO MUCH on extra ammo so we will always have a stash "just in case" its outlawed..
If we just spent half of that money on supporting the NRA, we wouldn't have to worry about maintaining a stash "just in case"
