Angry Gun Super Recoil Kit for Airsoft GBB Rifles (Type: WE-Tech M4 Series)

"adds some weight but that recoil is VIBRANT.
Can be adjusted to shorten bolt travel which increases ROF (renders bolt lock non functional)
When the travel is shortened the blow back is much snappier and seems less prone to malfunction.
I like it. probably gonna drill some holes in it though :D

"it's amazing. If you are a collector of Gbb. You definetely need this.

I think no gogd for game, because it eats double amount of gas .

But Kick is hard as double
Like me Shooters at home. This is great. Once you try , You don't want to go back nomal Buffer ever.

"had one for a long time and can say its great. adds noticeable recoil and is smooth. would buy again.

"This buffer is designed mostly to increase your rate of fire than recoil, although it does both quite well so it is an excellent choice for a drop-in ROF increase as the secondary spring on the buffer itself is extremely stiff (works like shocks on a car) and rebounds the buffer/bolt really fast and also drastically decreases the shock on your gun coming from the impact of the buffer hitting. My only thing is the ROF was too fast for my preference (only have 30rnds in the mag) it truly is 300% (3x faster cycle than stock).

I experimented with taking the secondary spring off and that slowed down ROF too much (about 50% of stock ROF) and put way too much shock through the gun as screws started getting loose and backing themselves out after a few mags. I have since got the RA-tech buffer and it suits me perfectly.

Pros:
Increase ROF
Decrease shock (wear and tear) on gun
Probably the safest 'drop-in' upgrade for the WE M4

Cons:
ROF is too fast for 30rnd mags and cant be effectively slowed down

"This thing is heavy and really does add recoil, with one downside it will eat up more gas and slow down bolt movement because of the added weight, i found that the cool down affect was really increased and i would get horrible amounts of shots fired for one mag not even a entire mag from one fill, do keep in mind this was in cold weather.

In all its cool if its decent temperature out but do NOT use in cold weather you will cry.
