"Plum Crazy," the famed polymer AR15 lowers manufacturer, is a r3VOL AND an InfoWarrior.
They were pretty much the only polymer AR lower in town, after ATF illegally raided (aren't all their activities illegal?) and shut down Calvary Arms who used to make really reliable polymer AR15 lowers. Post-seizure, the Cav. Arms' polymer designs got bought up by a company in Oklahoma.
Well, looks like Plum Crazy is either not in business anymore, or they relocated from Lake Havasu, AZ to LV, NV or sold off their designs to, and simply renamed themselves the New Frontier Armory.
The New Frontier Armory's polymer lowers look very similar to Plum Crazy's.
Sure, all AR lowers 'look similar,' but with Plum Crazy in particular, its 'D-esque' inverse-'C' shaped loop riser that protects the Mag release button is what made them more distinct; and the New Frontier Arms polymer AR lowers have the same 'C'-shaped riser, just like Plum Crazy. But I'm just speculating...
Either way, check them out, if you're in the market for a sub-$100 AR lower for your next build. As long as it's between 5.45mm Ruskie or 5.56mm NATO, to .300 AAC Blackout range, I would assume the polymer receiver should be able to handle recoils from those rounds; unless you intend on using your AR15 lower for some of the more exotic uppers like .450 Bushmaster or .458 SOCOM or .50BMG bolt action kits, it should be able to handle recoils from pretty much anything. Then again, who knows? Perhaps the polymer lower CAN handle the more heavier ammo.
The New Frontier Armory polymer lowers come stripped, or with trigger package. Personally, I'd spend a bit more on metal components and really good trigger like the Geissele SSA, as the stock kit the polymer lower comes with are plastic internals as well, like the trigger and hammer and even some pins, along with plastic safety latch (as many other manufacturers do). Just me perhaps, but I hate plastic components, other than structural encasing/shell, like a receiver, but not for moving internal components.
Predictions in due Time...
