After 6 month of usage and shooting more than 25000 twenty five thousand (vijfentwintigduizend) bb's with different weather conditions time has come to put my review of the replica.
Why KWA
For some one had military experiment it was hard to select the right replica which give me at lest the precise path to the target in (mid and short range) not to mention my old experience with (Bolt Action Sniper Rifles) was completely joke.."Since we're talking about war simulation replica"..
However today I am speaking about something else something officially considered as professional training platform at most security services institutions in U.S, and the reason for this because KWA industry mixed between the high quality materials and closely replicates the actual weapon. To deliver airsoft products perfectly fit professional training task and for some scenario-based training as well.
KWA origin
Having its origins in Taiwan is a U.S based company they're firmly based in Los Angeles County California.

My experience with KWA KM4 RIS
After several weeks of extensive research via the internet seeking what replica can reach my ambition i got to pick up the KWA KM4 RIS which recommended by everyone i met or ask online.
Now with long patience and suffering of waiting the KWA has been arrived to my home from U.S via the UPS service.
And between the legitimate right of worries and my happiness i opened the box.
Nothing was special or distinctive inside the box except black replica telling me you got what you paid for..
That touch feeling send me 12 years to the past.. The smell, the weight except the crane stock wasn't my friend from the beginning.
My firefox 11.1V 2400mAh LiPo battery already was fully charged and waiting to this moment as I am, and with a few minutes i loaded one of my KWA mid-cap magazine in 120 bb's and connect all of them together..
Time to rock and roll baby!
And such a beam, whole the bb's lined up it's way to that poor carton box make it center fly pieces such a small butterflies.. the magazine already empty but my finger still on the trigger enjoy listening to that symphony..
The most thing bring my attention where i had lighted candles top shelf start to play strongly due the air seal come out the barrel.
Anyway, now i have to downgrade my FPS due to the Netherlands rules and regulation which allow such this rifle 360fps.
I wouldn't open my gearbox and just keep it original stock, so i was searching on internet on how to downgrade your FPS with out open your gearbox, let me waste 5000 bb's just to comperes my spring to reach 360fps but at the end it didn't work and force my to replace my spring to guarder SP100 which gives me 340~350fps at the beginning later and with time reduced to 330~340fps.
The KWA KM4 RIS at the battlefield
Now it come to the serious test where the wide field and weather condition play multi-role affect your accuracy especially that day when i start back to play was frozen with light rain, however.
Since that time 17 of January 2016 till a few weeks ago i had no problem to mention with the KWA KM4 RIS the replica was perform extremely well and still.
All target between 60~70 meter was in my range and even superior by very responsive trigger system.
All target in critical angle was in my range and I've been able to achieved hit.
I have videos prove all these achievement and I'm not fan to KWA at all or any other but when it come to the reality i have to submit my view in neutral.
I know there is many good bran out there such as Krytac, Tokyo marui, CSI and just many others but this is my experience with KWA and this is what i have seen, no more no less.
Does The KWA KM4 RIS Requires Any Upgrade?
Absolutely no, the replica perform extremely well and ready right out the box.
But as i said above due to the Netherlands rules and regulation you must downgrade it to 360fps.
