I usually go for 60% of the average original sale price,More if something is broken or went through heavy usage.Take away the rough value of the sliding stock and sling plate from your sell price. I'd sell the mags separately,which I go for the 60% of RRP too.

If you're selling mags with it, that would make it up to approx the original value of just the gun. Take off the cost of a replacement stock.

it would of come with 2 mags - ics do this to most of their guns
