Is there any way to tell difference between cast and forged? The reason I ask is I have an older DPMS and all the markings on the lower are in raised letters as opposed to the newer receivers that have them set in. I have heard people talk about the problems with these and I would like to know what I have.

Check out the Olympic Arms web site. They used to have a photo comparison of forged vs. cast. If your lettering is raised then yes you have a cast receiver. I don’t know how the DPMS cast receiver quality is but I do own a Oly cast “Plinker” receiver. Let’s just say it’s serving as a platform for my sons .22LR AR.

I find that both the action and feel of the receiver are rougher.

Slide a finger over it and it seems that a cast lower or upper will have a grain to it.

Mine does feel kinda rough.But other than that all the edges are crisp and no tool marks at all.It is a very nice looking lower.

Comparing photos of the DPMS cast receivers vs. my Oly cast receiver, the DPMS seems to be of a MUCH higher quality.

You more than likely will be fine with a cast lower unless you are abusive or buttstrike your rifle.

...or accidentally have it fall over 18" on to the stock! Skip cast lowers if you can. Otherwise, expect about anythig.

proof that cast is now inferior, especially for what forged ones are going for nowadays i dont see the point.

Agree with Eklik There must be a reason why Olympic went to forged on all there units including the "Plinker Plus" I think there used to be a thread on some cast catastrophy -Pardon that one. Olympic claims it is an improvement(cast vs. forged_

I've only heard of four or five times when an AR receiver cracked or broke in some fashion. each time I did see or hear about it, it was a cast receiver. Meanwhile, I dont know if I have ever heard of a good forged receiver breaking or even wearing out after many decades of use. Im sure it happens but... I'll pass on the cast stuff.
