I was in a local gun store today and the owner handed me a new Bushmaster AR-15 he’d just gotten in and said, “Check this out!”
THE DANGED THING HAD A LOWER RECEIVER MADE OF BLACK PLASTIC . . . instead of aluminum!
Is this a new development? It is surely new to me . . . then again, I’m just getting into the black rifle part of the sport.
Wow . . . a Tupperware AR 15!

Its the Carbon-15, they’ve been out for a long time. I think the company who was selling them before Bushmaster bought them was Professional Ordnance or something like that. They used the carbon fiber during the AWB to bring their AR pistol in under the weight restrictions on pistols under the AWB.
Carbon 15.
Treed.
Could also be Cavalry Arms, but I don’t know of any partnerships they’ve done with Bushmaster.
Carbon 15 and Cav arms lower are a different animal.
Were the pistol grip and buttstock integral with the lower? If not it’s probably a carbon 15 lower, and you need to steer very, very clear of it.
sabre defence also sells one with the cav-15 polymer lower, i found one about a month ago for 869$ and bought it. it came in a sabre-marked assualt case with two 30 rd. mags and a bore-snake kit in one of the pockets. it is an a1 stock, i beleive they called it a ar=lite, i gave it to my son-in-law,he’s crazy about it. made a fine gift for free,for sure. [along wih a dozen assorted mags, and 700 rds. of good ammo]
Polymer lower receiver = why?
Because booger eaters will buy it. People will buy junk like Kel tec pistols and Ruger LCRs or whatever the fook they’re called. The Carbon 15 is the biggest piece of shit I’ve ever seen. It makes an Olympic Arms rifle look appealing! :eek:
Back when I was still actively eating boogers I picked up some kind of AR thingy in a trade and it was in a CavArms polymer lower. The FCG popped apart after 25 rounds and I couldn’t get it back together. That was called a “clue.”
Usual arguments pro:
It’s lighter.
It is more corrosion resistant.
My response:
Has anyone ever had an issue with the weight or corrosion resistance of an aluminum AR lower?
:rolleyes:
It’s like a Glock AR! 
This thing should pick up lots of supporters really quickly and it should not be a surprise for anyone.
my thoughts was that even if the polymer lower did’nt work out,the complete sabre upper,mags and case was basically worth 869$. maybe it will be okay, if not i’ll get him another lower,
You don’t see the Carbon come up on this site much because most shooters here have seen the light.
But when people would ask about the Carbon on TOS (after falling in love with the light weight when the picked it up in the gun store), I’d offer to make them an AR out of Styrofoam.
The sabre gun is a far cry better than the Carbon. It don’t like a poly lower, but that one is the better choice by far.
My Cav lower has treated me extremely well. Fine company and great guys to do business with.
The lower is very light and cuts down on vibration/recoil quite well. This is the first time I’ve heard of someone having a problem with theirs.
Its been out for a while now, Probably before '95. They still suck to this day
If a plastic lower with an nonadjustable buttstock and pistol grip is your thing, then rock on brother! I can’t see a compelling reason for it. No comment on if the guys who run the business are the nicest guys in the world - to me that’s beside the point.
When you say it cuts down on vibration/recoil, how do you mean? Do you have vibration or recoil issues with a standard AR?
What is your experience with CavArms products, Atwood?
The original Carbon 15 ARs came out when I was till working selling guns. We got several in, and then back in, and then back in, and then back in… you get the idea. I do believe that BM has made changes to the original design, but the whole concept is flawed.
Cavarms is a company that’s run by good guys, and I have owned one of their lowers (past tense) one of their lowers without issue, but post-AWB they make little sense to me.
I don’t have “issues” with standard ARs but I do notice significantly less vibration and recoil with the CavArms lower.
Since I’m a non high speed low drag civilian, I don’t find my myself constantly adjusting a stock for armor, inside of vehicles, etc… The rest of you might have a more exciting civilian life perhaps.
I’m not saying it’s for everyone but my CavArms lower has treated me well with no problems whatsoever.
