"This is a great budget gun, and it has a ton of features that you wouldn't normally get with other guns in its price range. I don't think the internals are Marui since it looks more like an S&T build. Regardless, it plays beautifully if used correctly. It has an ABS body which is durable to airsoft's extent, but will definitely break if you hit it against a tree, hard.
The charging handle is pretty flimsy, and with its tendency to break under constant usage, you can't really do the signature H&K charging like you can with full metal guns, although the real G36C is made of polymer. Remaining on topic, I would recommend switching out the inner barrel for an Angels Custom, or heavily polish it and don't abuse it with bad BBs. Staying with barrels, the outer barrel assembly was solid, but I would have loved to see a metal outer barrel because it DOES interfere with where your barrel points if you manipulate it enough.
Although it is a budget gun, this G36C is amazing to upgrade. Quick change springs are something you don't see much nowadays, but I can drop an M120 into this within minutes. Be aware that taking the gun apart will make it difficult to reassemble the trigger assembly without an extra set of hands since it IS a micro trigger. This is both a pro and con, the former being true if you don't intend on making gearbox upgrades.
The piston's cylinder is a bit weak, so I would suggest hitting up Angels Customs to get yourself a new, stronger, and more tight one. Outside of the gearbox, you have a high-speed motor. I highly suggest a high speed AND torque motor to replace, because the micro trigger and gears give it excellent trigger response granted you are using the right battery. You CAN HPA this gun, but some breaking down will need to be done unless you find the right V3 Fusion Engine.
I could use some 14mm negative threads underneath the plastic flash hider since I wanted to add a tracer unit to the end, but there were none since the outer barrel assembly IS plastic and would not make it a viable option. There are some full-sized G36 outer barrel assemblies that Evike sells in order for you to up your barrel length and versatility. These are a great buy.
You will get an RIS system around your handguard, which DOES have metal rails. These are a great addition that sets it apart from the JG G36C, even if you could purchase them (also at Evike). The top rail is a polymer, which was a slight disappointment, but it was durable. I found no issues roughly remounting sights onto it, and some wear is evident but doesn't hinder the affixing of your sight in any way. The folding stock does NOT have a rubber pad, but you can easily replace it with a Matrix one if that's what you want to do.
The G36 platform is extremely modular, so most aftermarket G36 parts WILL fit it. Essentially, this is a great buy if you know what you want to upgrade. The externals are beautiful and replicate this G36C's real steel counterpart. This gun IS LiPo ready, courtesy of my own testing. However, don't be fooled by the term LiPo read, because it is simply a term to describe durable gearboxes.
SCROLL DOWN HERE IF YOU DO NOT WANT TO REAL ALL THIS ABOVE
+Great accuracy and decent FPS out of the box, especially for a gun of its length. Perfect for CQC if you aren't intent on upgrading.
+Metal parts where it is necessary.
+Extremely lightweight and comfortable to operate with.
+Modular platform, it is compatible with other models in its family.
+Rear sight is adjustable for windage and elevation.
+Upgrading the internals is super easy and will not hinder too much for too long.
+Durable build won't mess you up, given you don't harshly treat it.
+Converting to GBB, EBB, and HPA is as simple as other guns, some easier than others.
+Hop-up is great, a bit better than an AK and M4 in some cases.
+This gun is crazy solid. You won't get anything around flimsy alongside the charging handle. (I do suggest buying an EBB charging handle to replace.
+Metal RIS and strong polymer upper rail.
-Charging handle will break on you after using it a lot.
-Mostly polymer build might break if you heavily abuse it.
-Stock pad is plastic, not rubber.
-Not really too much of an issue, but the top rail is polymer and not metal.
-Exposed wiring in the magazine well will require some slight adjsutment to protect it.
-Magazine pouches for the G36 magazines are hard to come across without getting overly large.
-Plastic outer barrel, and no threads beneath the flash hider.
-Internal gearbox grease job is rushed. I do recommend redoing it.
-Inner barrel isn't the best, grab a new one and flat-hop it for even better accuracy.
-You don't have one.
Whew, that took a while. Anyways, this is a great buy, and it can rank alongside Krytacs and its KWA cousin if you get the right internals for it.
"The gun itself is ok, the price is a little too high for the quality, but still acceptable.
The mag isn't really good though, mine fell on the ground once and broke comeplelty.
Overall I would say it's worth it to buy this
