Ordered this to replace the Vltor stock on my King Arms Tanker ( http://airsoftdepot.ca/catalog/product_info.php?cPath=102_146&products_id=2446 ) so I could fit it with a 9.6v. Its build quality is a lot better then I was expecting for $20. Fits the Buffer tube perfectly, better then the stock it came with. (Maybe a bit tight for some but no rattle or need for any tape shims) I did not like the look as much as the default but its growing on me.. Great Buy on a budget if you need the battery space. **note: if you use a 9.6v Nunchuk it will fit a bit loose, if you wrap a small amount of paracord (or tape?) around both sides of the battery and it fits perfectly with out rattle**
