RWA Agency Arms EXA barrel change

[Brettpixel]

Hey guys but of advice. 
Does anyone own the AA EXA glock ? 
looking to buy one and swap the barrel out with the RWA AA barrel to give it a more authentic look. 
For some reason Red Wolf says that these barrels will not fit anything other than a TM glock ? 
is there any reason why it had anyone managed to fit this to the EXA with some modding ? 
any help will be appreciated. I’ve added some pics too

It will just be one of those parts that at not compatible with other manufacturers…

Yup, the EXA is UMAREX spec (i have one) and the outer barrel is different, unfortunately unlikely to be compatible. ?
