The AMT Lightning 25/22 action is stainless. A 10/22 clone. If memory serves there were two different barrels. Mine started as the full stocked heavier barrel version but wasn't what you'd call heavy. Now it wears a threaded Ron Pence barrel with match chamber. Works perfectly just like a Ruger, and is very accurate.
The stainless Lightning AMT-Ruger clone pistol was also good. For years I shot ihmsa smallbore with one. The bore was rougher than you could imagine and looked terrible, but the gun shot extremely well. A friend had one and his was also very accurate.
