Is there any upgrades for the bt omega such as apex barrel or e triggers?

i have the omega the bt apex 2 barrel in bt4 threads should work. unfortunatly the the egrip just isnt in the picture for the omega. the reciver or where the trigger is, is an all aluminum caseing so without major modification ou wont be able to put one on. however if you buy a diffrent marker in the future you can always experiment by moding it to put an egrip on let me know if you do i'll be interested to see if it worked or not.
