EG Breechblocks! Issues!

[G.T.]

Hi To all, I have quite a few EG post war made breechblocks, the are marked on the bottom with a part number, bo stamped or engraved, and another electro penciled on. Anyway, they look nice, and although you still need to fit the parts somewhat, they can be used, it would seem, as a nice replacement for the blown out blocks from past history. Well, it turns out, not so much!!!! The problem with them is that they will strip a round from the mag and feed it anywhere from half to two thirds of the way into the chamber and then it will stop, SOLIDLY, and that's it, a tight jam? If you swap out an original toggle train, or original breechblock, it will work fine, kind of, sort of, eliminating the barreled receiver, feed ramp possibilities. Anyway, if any of you have run into this, please feel free to join in on the discussion! In the meantime, when my hands heal up from the toggle pulls, I will revisit ... best to all, til....lat'r....GT
