I used it recently for a Deringer rifle build but I went with the gooseneck cock option. On mine the sear arm was not low on the plate as is normal. It was up about 3/16, maybe 1/4”. I made a new sear then had to make a new sear spring. It’s a very snappy lock now. If the high sear arm does not bother you (if that will not be a problem with your trigger) It should be fine.
