    I'm not into the polymer lowers.

    Maybe for a dedicated .22 lr build, for 5.56 PASS.

    with lowers available at $69 from PSA I would pass - but at $35 it may be worth testing out as long as you have a backup in the PSA

    I built one last year.
    Had the parts sitting around.
    Placed a 20 inch pencil barrel upper(5.56) onto it and took it to the range.
    Fired 300 rounds and not one problem.
    Service grade for accuracy.
    All of my mags fit, used four types/brands, steel, alum, plastic.
    All feed and dropped free.
    Have since built three more for other people.
    Two 5,56 and a dedicated 22lr.
    No one has reported any problems.
    My wife shoots ours :upeyes: once a month and still no issues.
    She likes the lite weight.
    Hope this helps...
    My SHTF weapon of choice is still one of the FALs:wavey:

    I agree with the above poster that mentioned caliber. For a .22LR, polymer fits the bill. For .223 polymer would be my last choice especially with other options like PSA being as inexpensive as they are.

    I put together a New Frontier poly lower AR last year. I had a spare upper and BCG.
    The complete lower with internals and stock was $79.
    It has worked perfectly through 500rds so far...I like it.

    For $35 I would buy several of them to play with. Polymer lowers are the wave of the AR future IMO just like the Glock was the wave of the future of pistols.

    BTW, I have a couple Cav Arms lowers which work well.

    Glocks were designed for polymer from the beginning. So was the SCAR.

    The AR platform was not. Look at all the attempts to make a polymer-framed 1911. They pretty much all suck.

    $35 for a polymer lower, $50-70 for an aluminum one made to spec(even if it has a cosmetic blemish). Not a hard ****ing decision.

    After seeing pictures of that polymer AR lower with broken receiver pin holes...I really lost all confidence in any and all polymer AR lowers. I have never seen an aluminum lower break.

    I have two. One is a dedicated .22LR and is great fun. The other is an ultra lightweight built for my 5'1" Irish Redhead (87lbs). Both have run flawlessly, several thousand rounds in the .22 and about 800 on the 5.56. I have a spare complete lower on a Spikes Tactical receiver just in case.

    hopefully, on your ignore list
    For $35, curiosity would get the better of me. Why not? You have other rifles if you ever find yourself in N. Dallas needing a Noveske and a Glock with a 30 round mag in a drop leg holster.

    If a viable plastic had been around at the time the AR probably would have been designed for it. It is really immaterial what it was designed for.

    How do you figure? The dimensions of the receivers were designed with aluminum in mind. Trying to replicate it in polymer is going to sacrifice size or strength. You can only sacrifice so much in size before you're unable to use standard parts.

    I'm so glad a mechanical engineer such as your self has chimed in.

    I shouldn't have to remind you that many things previous made and designed of one thing, i.e., wood, stone, bronze, copper, brass, iron, steel, aluminum are now made of something else.
