Battle of the Best 22 Survival Rifles: Henry AR 7 vs. Marlin Papoose

I've had an AR-7 for many years. The only failing I've found with it is the front sight. That piece of plastic will move from left to right and back with vibration. I've never looked, but I imagine some one makes a steel or aluminum replacement that can be secured.
