Tipmann A-5 with RT, progressive barrel, 20oz Co2 tank, CAR-stock
Gives you improved acuraccy
C02 tank gets in the way unless you have a drop forward
This stock wont stop moving unless you tighten the little srew up REALLY tight. The co2 tank also gets in the way unless you have a dropforward or a remote. And the velocity ajuster always changes. But if you fix those problems its a good stock that will give you much better accuracy and a more military feel.
if you want something thats simple, dont buy this. But if you want a colapseable stock. get this.
