Plum Crazy Lower Rec?

[spleify]

I'll be curious to see your opinions of this.

Thanks

I wonder if its comparable to carbon 15 or cav arms.

I find these rather fascinating as well. You'll have to let us know about these once (if) it shows up.

Really interested in hearing how it holds up at the range with 1k+ rounds through it.

Well as has been pointed out, all the real stresses on the firearm are put on the upper receiver.

The main problem, according to my readings, is that since the design calls for aluminum, there is at least one weak point if you make it from polymer. Check out where you screw in the buffer tube and where it connects to the rest of the receiver. Pretty thin right? I reckon thats where it'll break if it does.

Now polymer lowers aren't a new idea. Bushmaster (I believe) made them before, as did Vulcan arms (which, like all Vulcan arms things, was shit.) I have heard (but have not confirmed) that the guy who is making these had some kind of hand in designing the Bushmaster polymer lowers, and has tweaked the design a bit.

Enough so that its a viable piece of kit? $99 for a complete lower rec would certainly help bring about quite a change in the economics of a DIY AR-15, but I dunno. We'll see I guess.

Vulcan/Hesse/Blackthorne have been making polymer lowers for years. They have universally blown chunks. Like Pancho pointed out, they had a tendency to break right around the rear takedown pin area.

Still not shipped. I am beginning to get irritated.

a dedicated 22 rifle can use a side folding ACE stock. be something akin to the Sig 522.

I do have one of these lowers. So far, it has worked out fine with 250 rounds through my Rock River upper. The upper was a bit snug on the rear lock pin. but it seems fine now.I was a little concerned about the polimer small parts, but they seem to be holding up fine. For the price, not a bad lower. I think I am going to get a stripped Rock River lower when something happens to this one.

Welcome to the forum, newbie!

with aluminum lowers at $70 I'd just get one of those
