What's your opinion on Polymer Lower receivers?

lhshooter · 01-02-2013, 07:53 PM

Just wondering what you guys think about Polymer AR 15 lowers? I personally am not in the market for one...but just wanted to generate some traffic...

On the one hand, you have Glocks, USP's, SigPro, etc. all handguns with a polymer frame...
As for polymer AR lower... the jury is still out on that one. I'd prefer the 7075-T6 forged aluminum lowers.

Bushmaster Carbon-15, anyone?

jb2925 · 01-02-2013, 11:59 PM

Had it, shot it, sold it! Loved the weight, Its about 5lbs. empty, but never felt comfortable with it. Wasn't impressed with the accuracy either. Not sure if it was the barrel, the polymer receiver, or the shooter. Seemed like when you got it heated up a bit, it was all over the place.

Not knocking Bushmaster, I had another M4 profile Bushmaster barrel, and that thing was accurate. Wish I still had it. A heavier barrel would defeat the purpose the Carbon 15 though.

I loved shooting the 22lr kit in it with a 50 rd drum. Nothing brings a smile to your face like watching a fist sized hole materialize in the paper as fast as you can pull the trigger.

Probably not going to matter soon.... we will all be posting "Hey remember those poly lowers.... "

i think it would depend on the application. a .22 plinker? a five-seven conversion? 9mm carbine? probably OK.. for the standard 5.56? pass get a metal receiver

It works, I know it works and the guy on the business end will know it works. I'm getting to the point in life where I don't chase every jack rabbit that comes along. If something is proven, works well and is in the "arsenal" it won't be replaced unless there's a real proven game changer that's needed.

Actually, 9mm has more bolt thrust momentum than the 5.56.

No polymer lowers for me. I like the feeling metal. I wouldn't be comfortable with it.

Well said!

I have a Plumb Crazy lower with close to 1000 rounds thru it.
Zero issues, fits tight and I like it.
Price was nice too.

No experience with a polymer-lower AR. My general experiences have been:
My little S&W M&P 15-22 has a polymer lower. Guns an eat-anything little tack driver.
My SP 2022; same.
My Keltec .380 ... got it as boot in a trade. It's function and reliability have surprised the crap out of me --in a favorable way.
Got the LCR in .38/.357M. No complaints at all.
Suppose it all depends on the gun itself; so far, I haven't felt screwed over at all. All of 'em, for the price paid, have been pretty dang sweet.
Next gun, though ... 1911. Going old school. Looking forward to it.
