I have used a wide range of guns from low to high ends.
This upgrade will put the a-5 up there with the high ends.
20 oz. C02 (soon to be 68ci 4500 psi HPA system)
4 inch drop forward
Fast, relaible, good battery life, easy to install,
doesnt like heavy weather
hard to see speed and mode adjusters
I got this upgrade when i bought my a-5 and i must say, it is one kick ass upgrade. it is very fast and somewhat weather resistant. I also own a Angel 4 and the e-grip can almost keep up with it. the angel is a faster, but it is also fully electronic. the a-5 with a e-grip on it can be placed right up with the high ends and should be. i use this gun for forest, scenarios and speedball and it does excellent in all of the fields. BUY THIS UPGRADE RIGHT AWAY!!!! you wont regret it.
i would highly recommend this upgrade along with the flatline, it just makes the game so much more fun. buy it.
