Works for me

When I ordered this I was skeptical that it would shoot without key holing the bullets. I used 22 cb shorts and it worked fine. I mounted a laser on the barrel since it didn't come with sights. and it is consistent as long as you don't rotate the insert. For the price of a box of ammo how can you go wrong.

.22lr rifled scd

Kennesaw cannon made this insert a few year ago, i think runway just took the relay. I'm sure you guys didn't even buy the damn thing. It is very well made with quality polymer and a nice rifled steel barrel. although it is not comparable to a real .22 rifle it is a good survival tool to put in your bag.

Sub-caliber insert

By 'corrosion resistant' they mean it's made of plastic. Really misleading. The only metal is a thin piece of barrel insert that compares with an old car antenna; probably lasts only a couple of shots. Go for the other one they sell that's all metal and only a few bucks more. They should be ashamed to sell this piece of junk.
