Tippmenn A-5 with modified Barrel and stock and a few other things
-i shoot real guns, so this helps me shoot better
-if the screw on the stock comes loose it will wobble
As for the screw coming loose all you have to do is tighten it and it wont come unscrew for a long time. Another thing i dont like is it wont allow you to use your sights but it dont matter all it takes is a little getting use to to shoot just as good if you were using your sights. Kinda hard to clean paint off of the part the stock slides on. The pros deffinatly out way the cons though. It adds a great look and it really helps if your use to shooting a real gun. And it actually kinda cheap($) compared to the solid sniper stock which i have tried and didnt like it was way to heavy, this stock is very light. Over all agood product.
I recomend this product very good; -1 for cleaning probs and screw coming loose.
