"if you're looking for a hi capa then look no further, this thing is great I got the pre upgraded one and I can't be happier.

personally I put in a cowcow short stroke kit and a speed dual bearing trigger right away and I'm in love with it very fast and snappy with virtually no recoil.

for me this is a base gun for a hi capa build and it will be nice having a nicer barrel and hop up unit until I replace it later down the road the hop up unit appears to be made cast copper with a brass wheal.
I believe the inner barrel is 6.1mm but I may be wrong.

as always evike had great customer service and very fast shipping

"This gun shoots really nice. Very comfortable and accurate right out of the box. This is my first hi Capa. Only thing I didn’t like was the Look of the enhanced magwell. Just not my style. Super easy to remove, held in with a pin. The gun comes with the replacement pin to install after removal too.

"Absolutely love this gun! I highly recommend this pistol if you enjoy the traditional hi capa look without spending a ton straight out of the box.
PROS- high quality build, extremely smooth blowback perfect for fast shooting, super sensitive hairline trigger and fiber optics make for great for getting of target fast, very cumfortable grip good for big and small hands, very accurate and consistent!
CONS- gas efficiency for the stock mag isnt the best, not able to finish a whole mag, but the extended and basic replacement msgs seem to work better, out of the box decent accuracy but highly recommend getting a 6.01 tightbore, made a huge difference.
Overall solid build, very reliable, beast on the field when you have multiple and extended mags!
