Should I assume that the precision rifles don't break? What happens if they do break -- are they repairable with easy-to-find parts?
A first tier ten meter air rifle will give you a lifetime of trouble free shooting satisfaction if properly used and maintained. The major components of the rifle will rarely give you any problems. Seals, o-rings, and springs are consumables that need to be replaced from time to time to keep the rifle in working condition. Parts are easy to find in the internet.
