Re: For you AICs stock conversion guys?
The one you linked is the spring version, and will have a large hole under the fore grip of the stock for the airsoft magazine to fit into. The gas version has the magazine in the same place as the real stock. The spring version also will not have any type of magazine cut out under the fake receiver of the rifle, but will be smooth. The gas version that you see for sub 100$ price tag in boneyards is a clone of a more expensive 500$ airsoft gun. Brand new, the clones sell for 200-250$, which is why they are found for 90-100$ when broken. The most common thing to break for them is generally the gas workings of the rifle, thus you will rarely receive one with a broken stock.
