CTAC AUG Version?
 

I recently just ordered a CTAC CTAU1 or an AUG in most cases.

I am having trouble finding a "decent" review or topics on it so i might as well see if i can try this out. I have a lot of questions on it on how compatible is it with other aftermarket parts specifically Lonex, Modify and Tokyo Marui as i have a lot of their internal parts laying around.
I know it's a Ver.3 Gearbox but im just not sure if other V.3 Gearboxes would fit. I had a G&G M16MAX Blowback one time and i "thought" i could fit a Modify V2 Gearbox in it turns out i couldn't it didn't fit even though the gearbox looked the same as G&G Gearbox.

So what do owners of this weird CTAC gun have had on it? Kinda lost on this one. :L

Usually, it can be wise to ask *before* ordering.

I doubt there is much info on CTAC. They usually rebrand low quality clones, then sell with a high markup, so you need to know which AUG clone was used.

If it's a standard AUG v3 that is used, then it should fit. The reason your other project didn't work is because of the blowback, I presume.
