Can anyone that owns a GHK AUG take it apart and tell me what parts are composed of at least some iron (probably steel)? I am interested in what exactly GHK is using for materials in the rifle. I know that the outer barrel is some sort of aluminium alloy (a few manufacturers make a steel replacement, however). The frame is plastic, as it is on the real AUG. However, what about the trigger box, bolt carrier, fire selector, and upper receiver (including the integrated scope)?

I operate the Steyr and I am also an owner of the GHK.

 

The Steyr AUG uppers are "mostly" Aluminium with embedded steel bits at the load bearing parts.   The reason is because the barrel trunnion is actually on the upper receiver and is "floating", it is fixed in place in 3 points, the receiver locking pin (steel), the front gas block and the breech (steel).  The front gas block is steel holds the monopod, and locks in place onto the upper receiver.  If the upper is aluminium then those 3 locking points would have worn out very quickly.

That is very helpful. Thanks!

 

I find it kind of insulting that the GHK AUG lacks a lot of these steel parts. For the price, you would think it would have a lot of steel components?!! Are there any manufacturers that make a steel bolt carrier for it? Hephaestus and a few others I know make a steel outer barrel.

The GHK is on the low end of the price range for GBBRs,  I think most airsoft consumers are happy with it.  Weight wise its a 200g off the real steel so its not so bad.

 

There is no need for a steel bolt carrier at this stage.  The GHK bolt carrier is sufficient in design to take the knocks, (unlike say the SCAR bolt carrier), and as demonstrated with most guns an aluminium blowback nozzle is generally not the best idea either.

 

I do not think a steel bolt carrier would be wise given what keeps the bolt carrier in place is an aluminium upper receiver with no steel inserts.  To change the bolt carrier to steel you would need to change the cocking rod and Op rod also to steel which would significantly increase in the weight of the bolt, decreasing gas efficiency and wearing the upper and the FCG.   Remember on another thread, I had warned about over upgrading and not throwing money into solving a non-problem.

 

Steel barrels are definitely a welcome since that is basically why the GHK doesn't feel quite right, but what I am more concerned is the use of the field stripping lever increases the wear on the barrel locking lug, which is brass and is slowly being worn away by the upper receiver. 

 

The GHK Steyr AUG is, in my opinion, the best airsoft replica I have bought out of the box.  10/10 on Replicating the outer and the working parts, 9.5/10 on Materials used, 9.8/10 on performance and efficiency, and 9.8/10 on durability.  Its both an Art work and a technical masterpiece.  There are some that has come close, but none so close to perfection.  Just a shame its a Steyr AUG (and not an M4, or other more collectable rifles <FAL/G3/etc> )

 

I have had friends who have been playing airsoft and have had many GBBs also said the same thing.  Tis a shame the M4 style ergonomic platforms are still what most people are used to.

 

I haven't bought the GHK M4 atm, so my opinion may change.  The GHK G5, while not a replica, is pretty hard good also.  Just not their AKs.  Would take a WE AK and tune up, rather than a GHK.
