More noob questions,

First, how can you tell if a M1A flash hider is cast or forged?

Second, has anyone had their M1A "cast" receiver fail?

Thanks!

some cast flash suppressors will have a visible casting line, some won't.  some usgi fs were cast including h&r.  some people will tell you a cast fs will make a different sound when struck with a tuning fork - i don't believe it.  there is no easy way to tell that i'm aware of, all modern commercial fs in the original gi pattern are cast.
i have never heard of any failures - if catastrophic failure is what you mean - with sa cast receivers.

Thanks for the response. I have heard, from some purists, that only true USGI flash hiders are forged. All others are cast. I do not know if this is true?

I am also trying to understand why some prefer forged over cast, like there is something wrong with cast parts? Yes, I was speaking in terms of catastrophic failures of the receivers, again some look down on cast receivers. I just have never heard of a failure of a cast receiver and wanted to know if anyone else has?

Cast or forged is a moot point with flash suppressors. After the first year or two of production, all USGI M14 flash suppressors were cast, or so I'm told. As far as your SA Inc. M1A receiver being cast, don't worry about it. Heat treatment is the critical factor in durability.

Forged is better there is no doubt about it. The issue is wether or not forged is necessary. 95% of all civilian M14s/M1a's are cast receivers and they're just fine. If you're looking for the best rifle you can buy right now I suggest an LRB the build quality is much better than an SAI. There is nothing wrong with an SAI rifle as I love my scout, but time maybe running out on owning one of these so big the one you really want.

There is a step at the rear of the cast USGI FH sight base and none on the forged USGI FH sight base. All H&R FHs are cast, but SA (U.S. Govt') made both types. I have never seen a New-In-Can TRW FH & have never taken a  NIC Winchester FH out of the can for inspection. Different will have better info.

Exactly. But both forged & cast USGI FHs were all originally manufactured with a bayo lug.

So leid, it is your learned opinion that the bottom pictured FH w/bayo lug is USGI Forged, correct?

That FH has the external appearance of a forged USGI FH and it has a bayo lug. I would say it is a USGI forged part, yes. But I do not stay abreast of all the latest reproduction FHs. Different will have the best/ most current info available.

I hope you are right! If so, good news, that is the one I just recently purchased.

I think you did fine. I am looking at a cast H&R FH now and everything I see is correct on yours for a forged USGI FH. Both cast and forged USGI FHs have failed after a lot of use/abuse. But I will take a forged USGI FH especially if it is going to be reamed to NM specs. Just me.

Yeah, the main reason I started this thread was that I recently purchased a NIB (unfired) SA M1 in .308. This was a "new" production of the Garand by SA back in the late 90's and early 2000's. I have caught a lot of grief from the purists stating this isn't a "real" Garand because has a cast receiver (just like all the current production M1A's) and is not forged like the USGI WWII receivers. So, I was curious if anyone had experienced or knew of someone that had a failure. Doesn't seem like it has happened, not that it couldn't, but I've never heard of it. Funny though how it is perfectly acceptable to own a cast M1A but not a cast Garand. Go figure.

The trouble we have with it is that we don't see the sense in buying a reproduction when the genuine article is readily available and cheaper. The SA Inc. M1 might be new and pretty, but it isn't the rifle that saved the world from tyranny. It isn't the rifle that our fathers and grandfathers used to slay Fascists and Commies. It is the last U.S. military issued rifle that we will ever be able to buy and they are not making any more of them. If we could buy a USGI M14, we'd feel the same way about the SA Inc. M1A.

This.

Harrington & Richardson and early government Springfield Armory flash suppressors were made from castings.  TRW and late government Springfield Armory flash suppressors were forgings.

  I was waiting for someone to chime in and state that.....   From what I even read ( bad memory here). They  found it cheaper to make the Forged ones vs the CAST. I know I read it........ WarDawg
