T1x into a T3 Bravo

Hey guys,
Just after some comments about making a T1x sit in a T3 Bravo chassis. From what ive found its a matter of milling out a slot between the trigger well and the mag well? Seems pretty straightforward. Any other problems people have encountered?

Cheers

If anyone is interested, I got the t1x into the t3 bravo. It requires a bit of work but it’s working mint for what I needed.

Just zip tie and tape it in. Much of a ball ache to make it fit?
