Does anyone have any experience with these guns? I would like to purchase a semi auto for my son.I looked at one at Cabelas today and I liked the way it felt. It was the 20 ga youth viper. It is a lot lighter then the Rem 1100 youth 20 ga. It was only $399. I searched the internet and saw very few reviews. The few I saw were mostly positive. Any one have any info on these guns they could share?
