E200 alternative stocklock

I was printing the E200, but when I did the stock lock piece it wasn't looking like it was really going to work. One time I was trying to remove it but I broke the loop on the back half of there receiver so I designed this as an alternative to not reprint the whole thing.

I think this one might be a little more secure but I never was able to try the original one.

The size of 33 rubber bands can work but 11 works best for me.

SUPPORTS ON!
