I know that forged lowers are stronger than cast, but I have never heard of anyone having trouble with a cast lower reciever. I bring this up because a local shop has some DPMS cast lowers. I'm thinking of buying one to build my next AR from. If you have had bad experiences with cast, let's hear it. Thanks Gump |
I had an older DPMS cast lower that had misaligned rear pushpin holes. I had to dremel the hell out of a rear takedown pin, and still had to use a rubber mallet to get it in all the way.  FWIW, the folks at Lauer told me that the lower would hold their finish as well as a normal forged lower. I thought that DPMS discontinued cast lowers a couple years ago? |
but no problems with function or breakage. I also not that it doesnt hold KG gunkote as well
Cast will typically have a grainy appearance. The mold separation line will be thin where visible (usually the front of the mag well and inside the trigger guard) and unfinished. Lettering is usually raised rather than indented. Generally they won't stamp roll marks on a casting so the company logo and such will be part of the mold, hence the raise lettering. |
