Review:
This is my first paintball gun I have ever had. After doing a lot of research, I picked the A-5 and ordered this car stock to go along with it. I practiced a lot in my backyard with the stock shooting bottles, and it helped a lot with my stability and overall aim; however, this was before I bought a mask.
Last week I got my mask - an NVader Elite. I put it on and brought the gun up to my shoulder, only to find that the mask got in the way of the stock, and I could not align the sights correctly. What a waste of money!
Since then, I pulled the stock off and reinstalled the original shock suppressor. I have been playing in fields and forests with my friends, and have been using my 20 ounce CO2 tank as a stock (flat bottomed) - lo and behold, it works just fine. Yesterday I played two 1v1v1 rounds, and came out with 4 kills, 0 deaths. You don't need this stock to achieve the A-5's peak performance - all you need is a 20 ounce, keen eyes and a steady grip.
I'm a fairly muscular guy, been lifting weights since I was 14 (i'm 19 now), so I have a very broad chest and shoulder area; I mention this because I'm not sure how well a flat-bottomed 20 ounce would suffice for smaller players with smaller chests and rotator cuffs. If you experience a problem because of this, I'd suggest trying out a tank butt stock, which would fit better on a smaller shoulder.
Conclusion:
This product is a complete waste of money and a complete waste of time. It makes the gun look great and helps aiming in competitive target practice, but has no field value whatsoever; and let's face it - that's the only place it really matters. It deserves the lowest grade I can give.
