polymer ar's

[UndeadViking]

Years ago, my friend and I each built one on plum crazy lowers and both experienced the holes for the hammer pins widening over time. After about 500 to 600 rounds the things became garbage.
Tried to contact manufacturer but never heard back. Chocked it up as a loss. Live and learn.

I now always go mil spec or better and never regret it. With the price of anderson/psa aluminum lowers, why go polymer?
I found the weight difference to be marginal.

If I may ask, what is your personal attraction?

was just thinking about a light weight 11.5" pistol build

i've a few of the first plums, both have over 1k or 2, and so far no issues, same with cav arms lowers, have a couple of those also, got in on the liquadation sale.

I too have a 1st gen plum and it has about 500 to 600 in it and I haven't cleaned it in 2 yrs. The basturd just keeps running. Mind you I shoot steel out of it as well and it's just the gift that keeps on giving.

while at the show last weekend I picked up a omni max & was surprised by the weight, I was looking for something around under 5lbs.

I had different intentions for my Plum lowers and am not disappointed yet.

As I stated, I put the walking pins on mine when I built them and I think it makes a difference in their overall longevity.

No problems yet, but I haven't ran thousands of rounds through them either.

If you are doing 80% lowers and can get them dirt cheap and I mean dirt cheap then yes buy them through them together and have them as a last resort rifle. That's cool. But if they cost the same as a Anderson lower and you are going to use it as a primary rifle dont do it.

Not an AR guy but from what I read on other forums it seems most feel the poly receivers are really better suited for .22LR builds.

Yup not an AR guy. You have no idea do you. Still loves to chim in on things he learns from others opinions. Most. Well I got to tell you. They make them for 308. 556, 9, 45, 10mm, and so on. Some are just poly. Some have steel embedded in their poly. I've seen a carbon fiber lower still with some steel plating. So poly is what you make it.

One of my CAV lowers is mated to my BeoWulf .50 cal.

It hasn't given any signs of wear or failure, and is tough as nails....

Im just giving my experience with a polymer at work while instructing. As I said personally I would spend a few extra dollars on a mil spec

Bit confused are we? You literally just posted they weren't good for more then a last resort, untraceable (80%) rifle and now are singing their praises.

You just can't help arguing the opposite of anything I post it seems.

I simply relayed what other guys who are AR guys have said about them.

[17-21-23]

Did you read the post? Or could you see it through your hate classes. I did not praise them at all. I just started FACT not something I heard from some guys that think they are AR GUYS. By the way Steve ,what makes a AR guy. Prerequisites please. I dont like them because in a combat situation they would not be my first choice. I would use them if I had to but not first choice. In my years of using AR15 and their variants I have put over 900,000 rounds down range. I would say I'm a AR GUY.

I wouldn't mess with polly uppers in any brand; too many failures but I'll vouch for the gen2 Plum Crazy. Literally 1000's of rounds. Was my first AR from a couple years ago. Stupid light weight.

[Elk34]

I have used them. Its hit or miss with the different brands.
