UFC G36 Extendable Folding Stock and Upper Sight Rail Set
(Color: Black)

"This set is very nice. The top rail, once installed, does not wiggle at all. The part slide perfectly on my KWA G36C. The stock however may need some modification for you. I had to sand a bit of the release button that allows the foldable stock to fold. the rest of the stock fits very nicely.

"Awesome pieces to add to your G36 rifle. Since this is based on the WE G39 series, this is not going to be a direct drop in for a lot of guns. In my case, I had to sand the back part of the gun just slightly in order to make it fit perfectly. However, despite being based on the WE platform, they improved the pieces from the original. The original rails were really flexible and easy to bend. however in this model, they added a metal rod to keep it structurally more stable. The sights are still not adjustable however. For the stock also concaves inward instead of outward like the original, however just like the original it is not rubberized, and they also made it so it doesn't split into two pieces if you adjust it too far. Unfortunately, if you hold it against your shoulder with an excessive amount of force (like if you were to bear hug someone) then it will collapse on its own. But from normal airsoft use I can't really see it happening.

Pros:
Looks unique
Lightweight
Stock has adjustable length
Stock has 3 position adjustable cheek riser
Improved from the original WE parts

Cons:
Sights are not adjustable
Stock collapses on its own if you use too much force
the pad on the stock isn't rubberized

anyway, it is still a great product and I highly recommend it if you want to make your g36 more unique and futuristic.
