Went out yesterday with a friend to try out the SSAR-15 stock and we brought along an M-16 to compare it to. I want to let you know that I am not a bump fire person and someone that is good at this would probably do much better than I did. Saying that, it is obvious that I had some problems with it. It took me 4 20 rd. mags to get used to it before I got a full mag dump on the 5th. Then after that it was hit or miss if I could do it. I'm sure with enough practice it could be reliably fired. The main problem I was having was knowing the correct amount of forward pressure needed to keep the rifle firing. The firing stoppages I was having were not a trivial thing either. When it would stop firing it was not as easy as just put forward pressure on it again to start firing, I had to manually cycle the bolt to continue to fire. When it stopped the hammer was not being locked back and was sitting on the carrier. This happened every time it stopped firing and I believe it was caused by too much forward pressure. For an accuracy test we had a 2'x2' box set out at 50 yards. For full mag dumps both the stock and the M-16 were equal in accuracy for the first few shots and then started spraying all around the box. All I can say is the M-16 had a smaller spray ring then the stock. Burst fire was more accurate with the M-16. As far as I could tell the cycle rate for both were identical. In conclusion: I have not made my mind up yet whether or not I will purchase one of these. I shoot right handed and pulling the stock towards my shoulder with my right hand and the front of the rifle away from me with the left is very unnatural. I WOULD NOT recommend this stock for any kind of life threatening encounters because of the stoppage problems. It is a novelty item that is fun to shoot at the range, once you get used to it, and will definitely lower your ammo supply quickly.
