My understanding is that if I want to run my Zenith as a sear host, I need to weld a shelf over the pin hole in the receiver and then remove the full auto carrier block at the rear of the receiver. I know adding shelves are a common procedure, but does anybody have any experience removing the block?

It's just a couple of weld points i believe. Should be pretty easy to take out.

Be sure to install the shelf first before removing the rear F/A carrier block. Removing the sear block is easily done with any grinding tool. Welding, on the other hand requires skill and a Tig welder.

Wow, really interesting read. Do carrier blocks differ between Zenith versions? Does the SP5K have a block as well?

The ATF is such a mystery.

The ATF is such a mystery.

The earlier ATI MKE have different style carrier block than the Zenith MKE, but do the same thing. Even the SP5K will keep the F/A carrier from being inserted into the receiver except it has a small pin at the top of the receiver.

As far as those weld points go, I can see one at the rear of the receiver near the "nub" that prevents the FA carrier from going in. Is the other one at the bottom of the receiver?

This whole time I was curious as to what these blocks looked like so I took some pics as soon as I received mine. Here they are.

Anybody?
