I have a friend who is looking to get rid of an AK. It's a Saiga Composite AK47 w/ a pair of 30 rd mags & a single 10 rd. Says he's only fired about 100 rds with it. No frills, nothing extra. Just base model. What's a fair price on something like this? My window of opportunity is pretty slim, and I know very little about AKs.
