Much more serious though was the up and down play in the barrel lock up.
If fired with the hand under the barrel, thus holding it up, it shot almost 1" higher over ten metres than with the hand under the fore end.
The gun was sold to me as being in excellent condition with very little use (less than 100 pellets). In reality it had a marked stock and rust on the top of the barrel so along with the above faults I decided to send it back to the seller and obtain a full refund.
