I like the idea of having two set ups like swaping to the gbb internals in the summer, and switching back to the AEG internals in the winter.

I am looking at the Beta Project GBB convertion and I was wondering If It could fit an A&K Masada ACR. Is it better off to buy a G&P Skull Frog challenge kit and then buy a cheap AEG for the winter? Are there any other kits you would recommend? I have seen the GHK ones and they lack a bolt catch and the bolt release function.

Thanks
