This is such a radically new design, there isn't much in my opinon to compare the A-5 to.
R/T and Flatline barrel
Unknown at this time.
Right out of the box, this gun shot with amazing accuracy. My shot grouping was dead on at 25-30 yds. A quick adjustment on the rear MP5 style sight, brought my grouping to site picture at 40 yds and beyond. Also a fairly quite gun with factory barrel.
The rate of fire with the R/T is indescribable. Electro's with elect hoppers, shoot roughly the same but at a higher cost when you add all things together.
The flatline is truly a feat of engineering excellence. Unprecedented accuracy and range.
I think the bolt (cocking mechanism) is alittle cheaply made. It appears to be "toy like. Besides that nothing bad at all.
I recommend this gun bone stock for the player with outdated markers that what to step up and have a marker that will perform right out of the box. Many upgrades are available that will make this a truly favorite on the playing field. If you like throwing allot of paint, the R/T is a must. If you snipe get the Flatline. If your just out to have fun on the weekend, buy the stock marker and you should have trouble free/breakage free play.
