What is needed to switch from classic body to Uli?

[Squirrel Bate]

Can I use the same body rail? Also, is their any work involved that I should know about if I get one when their back in stock? Is their any benifit to the cocker threaded Uli?

You can use the same rail. You'll have to take the twist lock pin out.

The benefits for having cocker threads? You can use almost every manufacturer makes barrels that are cocker threaded. Twist lock is dying out
