Tippmann 98 Custom with a 12"J&J Ceramic barrel and the Proteams F/X Stock
The stock makes the gun so much more stable and improves accuracy greatly.
Depending on what kind of mask you have, it kind of gets in the way.
Overall, this stock is amazing. It seems like guns were made for this stock. My game improved tremendously thanks to this stock. My hands shake badly and this stock helped me stabilize the gun so i could actually hit what i was shooting at. Yeah, its kind of expensive and you have to press your mask up against it if you want to use your sight, but i still think it's awesome. It's worth it because the stock is SO comfortable compared to the plastic and bumpy backs of some other stocks.
This stock is perfect for snipers and for people who have trouble holding the gun steady.
