H&K G36C Competition Series Airsoft AEG Rifle by Umarex
(Color: Black / Reload Package)

"January 11th 2026:
I am planning on giving this a better barrel and spring so it has better accuracy and higher FPS.
The only thing that has given out of me was the charging handle, which I was being a little rough with anyways and is easily replaceable.
I love the G36 platform, and this was my first airsoft gun. I now own this, and M4A1, AK74, M249, FAMAS, MG42, EV03 HELIOS, and an SVD but I love and use this thing as much as ever.
9/10

"Charging handle broke off and gun has problems wanting to switch to full auto now after 2 years of use. but still my go to primary weapon

"Things you need to know
The good
-Full steel tooth piston rack
-Non ported cylinder
-Quick change spring system that can be accessed by simply removing a receiver pin by hand
-Very robust gears and bushings
-Microswitch trigger system, can easily be replaced with a generic microswitch with minimal modification
-S&T mag and buffer tube adapter fit perfectly. The hole where the bbs come out of needs to be widened a little bit, but its an easy mod

The bad
-the original stock feels flimsy. but easily replaceable
-The charging handle is also very flimsy
-Inner barrel is aluminum

I threw in a high torque motor from an AK that I had laying around
I shimmed the gearbox
Threw in a M120 spring
Threw on the S&T M4 mag and stock adapter combo ($20, feels more sturdy now)
Threw in a G&G blue bucking

Im getting 370 - 2 fps

This is my favorite sleeper build. It sounds very nice. Pulls the spring with no effort. For $190 after parts. Considering that it came with that piston and cylinder (That's a pre installed upgrade in my opinion, considering that a lot of high end guns use ported cylinders and pistons with 1 steel tooth, which saved me money), its definitely a big bang for your buck, if what you like is great performance that will last.
