I have not used many other markers, so Im not sure, but I have used a stock A-5, and I prefer this.
Tippmann A-5 with the Spec Ops SAW Stock version of the EZ Air-Throught A-5A2 Kit.
(Anything you would put on an A-5)
Cant see throught the stock sights with my mask.
Broken down, its an A-5 with a cool air-through stock. Mine is a lot differant than the one in the picture, but in spec-ops eyes their all the same gun by name. My stock is a bit differant. Its nice as far as the air-throught. Some people might not like it but i love it.
I would buy it, or if you want, upgrade your A-5 with one of their many kits. Theirs many choices, and more coming from a great company.
