Did a couple of searches and found nothing other than it's a multi caliber lower.

Does anyone have any experience with these lowers?

Thanks

Avoid all of the plastic lowers except GWACS, they break.

Hogwash.

I have four polymer lowers, none of them have "broken".

Good "broken polymer AR lower."

Yes, I have one. Bought it to mate up with an orphaned upper that I have (from a 458 Socom project).

I've put about 100 rounds through it on a couple trips to the range. Used four or five different types of magazines (Magpul, Colt, GI, etc).

No issues. Everything is snug, magazines seat and remove fine. I'm sure it could be broken but then, so can a crowbar if you work at it.

I have a New Frontier that I am pretty pleased with.Have only put a couple of hundred rounds thru it but so far it has been a good buy. I put an inexpensive 16' upper from Midway on it and it was a cheap build. I am actually impressed with the trigger and it is also all plastic.

Like zimbabwe, I too have a New Frontier Armory lower, mated to a DPMS .223/5.56 upper with a 16" barrel. I've got several thousand rounds through it now and it's still working as well as the first day I shot it.

I don't know about the upper you're talking about, but I'm definitely a fan of New Frontier lowers...

For a few dollars more you can use aluminum...
