    Still not touching it with a 10 foot pole. No offense, OP.

    Interesting,.......do not believe I would ever buy one though.
    Had enough issues with Cav Arms.

    I havent replaced my AR15's with it. It will take some time before I would consider that. Needs time to prove itself.

    Well its interesting. And for under a 100 bucks if it stands up in the long run not a bad deal.

    Given the rather spotty track record of polymer lowers... a LOT of time to prove itself. I think it'll eventually be possible, but not yet. Hell, I think even the ACR has canned the poly lower and gone to magnesium on the newest models for LEO.

    And that makes sense,.....will be following this lower.
    It may well be the cat's azz! Only time will tell, but
    Bushmaster failed with the Carbon, Cav Arms failed with their's.

    Maybe I have a jaded opinion? :dunno:

    I agree for the most part. Neither were a good replacement for the anodized aluminum lower. I certainly am more cautious with this one than I would have been otherwise I think, and it is because of those examples you mentioned.

    That said, this seems to be decent. Time will tell.

    I hate basing my opinion on such little data, so this was more of a quick review of it with what little data I have available.

    My local shop has these for 99 bucks, complete lower with collapsable stock.

    That looks eerily similar to my Plum Crazy lower.

    So I just went to their website and watched the video on the destructive press test. To the layman it would look like they are comparing the strength of the forged lower to the polymer one. However, they are only testing the elastic modulus of the different materials i.e. how much elastic deformation the material can take and rebound to its original shape. It's a bit deceiving. Of course plastic is going to have a higher elastic modulus. Rubber can undergo an even higher amount of deformation and return to its original shape. However, would you want a lower made of rubber?

    I remember Plum Crazy posting some dubious tests before on Youtube that took alot of criticism as well. The 'ole butterknife' test as alot of people called it, because the owner of PlumCrazy was testing the durability of the metal and polymer lower by gently whacking it with a butter knife. He promptly removed the videos after all the criticism he got for it.

    To their defense, my Plum Crazy lowers have held up fine to the gentle range use and varmint hunting I've put them through. However, if Plum Crazy/New Frontier Armory wants to be taken seriously, they need to have a more serious marketing and testing approach.

    Saw one today, Plumb Crazy $135 I think it was. It felt odd to hold, not sure of it's overall quality but I prefer the traditional lower at this point.

    I have a plum crazy nut the upper is a AR 5.7. It is lighter and the round has little to no recoil or report to it. The trigger is much better than my Rock River( which is 5.56 on it). The plum crazy is lighter of course, but maily for plinking and varmint, of course i'm very careful knowing if I drop it, it will split , break or something. Never tried the 5.56 on it. It was a whim buy and really don't have any problems what so ever. For a 100 bucks my family and I have had alot of fun with it. Bought a 5.45 upper a few weeks back . considering trying it on the Plum Crazy also. Lowers are getting harder to find anymore seem to be going like hotcakes. Looking for another aluminum upper for the 5.45 tho.

    I wouldn't use a polymer lower with anything besides a dedicated .22 LR plinker.
    Definitely not the material you'd want for a rifle to stake your life on.

    Like I said I purchased mine on a whim and money factor. Personally I would Never put a 5.56 or larger on it.

    They did? Selling like hotcakes and very little (like hardly any) structural problems is a failure? There was a guy on AR15.com that kaboomed his Carbon 15 upper but it ended up being an ammo problem. :dunno: Just curious.

    Personally, I will stick to forged lowers, but the polymer craze is definitely appealing to the 100 rounds or less a month range shooters/plinkers.

    Well,.......the one I had was a POS. I've seen four with cracks.
    Two had the crappy shell deflectors depart upon the 1st firing. Three with mags wells that were out of spec. A guy had one
    in a Carbine class, ended up falling on it. Snapped the barrel from the
    upper receiver. With all those issues, I'd call that a failure in my book!

    Understood. Wife loves hers and it runs fine- that's my only expereince with one. Taking one to a rifle class is like taking a Chevy Aveo to a mud bogging event, though. Oh well.

    All that aside, they are popular for some reason. I can tell you that the only reason i ended up with a Carbon 15 was because I only gave $500 for it from a friend who was strapped for cash and I bought it brand new- unfired. That, and it got my bride into the AR game. Keep momma happy, right?

    Other than cost savings I see no point in going to polymer.
