A year-or-so ago I purchased a complete SG USGI housing for around $125.00...fully loaded and ready to plug-n-play. Today, these things are selling for north of $250.00 where I've been looking. My question is....how many cast trigger housings has anybody actually seen broken or can confirm that someone else has had one cracked or broken?

I let an early cast aluminum housing pass the other day for a selling price of $29. This was the very early style that mimics the looks exactly of the USGI. I am not talking about the Universals with the red and green dots on the housing, those were the second edition B4 they went to the box-housing. I think the next time I see one, I'll not let it get away. I'm just curious as to how serious the problem of cracked or broken cast housings can be? You can obtain a genuine USGI naked housing for around $100. Can it be almost 4X the quality of a cast replica?

Comments?

Okay, my *opinion* is that a *correctly* cast housing will be as durable as a machined (or braised) USGI housing. Heck, Ruger's been using castings for decades without problems. I even have three M2-style USGI housings that were cast by a company in New York for use in Vietnam.

Can a milled or cast housing crack? Sure. All it takes is a hidden flaw in the metal.

That said, I'd prefer a steel cast or milled housing to an aluminum one.

Cheers,
Richard

Thanks for the comments rg. I think it depends on who made it and how. I have an Iver Johnson that has a cast STEEL TH and it is made to exact dimensions as a GI unit. It also takes the same pins as the USGI. I know they made a couple of different versions and the one I have looks and fits the best. Universal manufactured at least two cast aluminum versions B4 they went to the box-style housing. The early Universal examples appear to be of the lowest quality among the commercials. I've seen one with a broken loop after it was dropped. I have seen one that was cracked when it was being removed from the receiver. Closer examination turned-up a flaw (void) in one side of the mag-well area....that's where it is thin...and it cracked. I've about decided to stick with the GI housings. I think it's too difficult to determine which cast aluminum housings may-or-may not be the "good" ones on these commercial carbines. We all know that alloys are now used all over the place in gun-world. Commercial carbine manufacturers just didn't get it right in some cases and I don't plan to spend anymore time on the issue.

Yes...I know Ruger uses casting and look at them. A reputation for building some of the strongest guns made.

Another *possible* problem with an aluminum housing is the hammer, trigger and mounting holes *might* become worn and loose. Steel pins are going to trump aluminum almost any day. (Many moons ago, I had a S&W model 39-2 that had an aluminum frame and a steel slide. It didn't take too many rounds before the rails became obviously rounded.)

Cheers,
Richard
