Albroswift Posted October 9, 2022 Report Share Posted October 9, 2022 (edited) Going back through some of the old builds, got to the 40SW Zombie Killer. Added a small block of aluminum on the mag release to hold the mag a little higher. Tried solder, muggy weld, one other "Aluminum" type solder/weld could not get a good bond. (After thinking about it later wondering if the AlOx media blast was imparting a oxide finish, go back to that later) Anyway, for proof of concept used JB weld. held solid enough to mill without coming loose. Gradually reduced the height of the block until magazine locked up in near contact with the closed BCG. Then set the ejector to just touching the top of the inserted mag, filed the top of the ejector until the BCG would clear. Threw a Cerakote black/ titanium stress and a CMC PCC SS drop in. At the gravel pit I could not find a round that would not feed, went through hollow points, flat points, round points, factory and handloads. 250+ rounds, little riser block still epoxied in place. No double taps with the CMC FCG. Need to learn how to weld/ solder aluminum but in the mean time solid shooter.
