Ar lowers any leads?

So found a FFL close by who is still willing to transfer lowers, might as well grab more before its too late. Anyone have any leads on any lower recievers?

YES! Just ordered an aero precision lower, kinda pricey but a bunch of AR gurus on my local forum have them and they say they are top notch. PISSED cause i sold my psa lpk thinking I could never get another lower. Tailo you have a pm inbound

PSA has a bunch of different lower build kits in stock currently. I like the ACS-L build kit myself.

Rainier Arms has DRD Tactical billet lowers in stock. I have no clue about who these guys are or the quality of them, however.

What lowers?

Bill's Gun Shop in Robbinsdale has a stack of CMMG lowers, but they're CMMG. Not gonna happen.

Only problem Ive seen with the AP lowers were the finish. I have a way a slew of em for my wedding and the finish was thin in spots on every single one of them.

A guy on my local forum broke one of those polymer lowers right at the buffer tube threads, he said under "regular" use too.

Dont know about lowers but complete ARs are getting much easier to find at normal prices here in Florida.

Cant buy a complete AR since there banned in NY. It was hard to find an AR since 2010 in NY, always sold out.

I would not ever touch a polymer lower. Ever. The AR platform is not like the ACR or SCAR- you can't have a functional and durable polymer lower.

I don't know if I'd go that far, it just hasn't been done yet. Getting a polymer component that has the same strength and characteristics as a metal component is not that hard, I used to do it for a living. The catch is that it takes a lot of work and will cost just as much as a metal one.

Who said im building an AR

Technically we do have till next April to register "assault weapons". And you can build an neutered ar (not happening)

The comment is based on what's been presented to the market thus far. The problem is that current polymers used don't have the rigidity or strength of forged or billet aluminum counterparts. This is why polymer lowers break at the receiver extension/rear take pin area, or else at the front pivot pin area. The weight savings of polymer just isn't worth it. You are only saving a few ounces, so it's not a feasible investment IMO.

And that's fair. I agree that what's currently out there isn't really very good and mainly because I'm sure they are trying to do it on the cheap but with some good engineering time and designing with the right materials and a good mold, it's totally possible.

In the cost of doing this, it'll be 97% engineering time and 3% material cost. Once the mold and stuff is done, you can run it all day, every day for very cheap. It's the up front cost that's the killer but once that cost is recovered, you can make a ton of money.

All of the cycling components in the ACR and SCAR are housed in the upper receiver, so the lower receiver can be polymer for those. The rigidity of the lower receiver has no impact on the operation of those two weapons.
With ARs, the receiver extension plays a significant role in requiring lower receiver rigidity and durability, as well as the need to stabilize the upper using both take-down pins. I have concerns about this with current production offerings, as we've seen with polymer pistols. The fact that S&W deemed it necessary to put the chassis insert into the M&P pistol is indicative of the current state of polymer use for current weaponry. Most likely it's an issue of what they're willing to use, and not what they COULD be using.
