Don't.

Around here you'll find little love for polymer lowers on anything besides a .22 and no love for anything from CTD.
I wouldn't use a poly lower at all when forged lowers can be had for under $100; there's just no reason to bother.

Meh, with the price of 'luminum lowers coming down, no reason to bother with a plastic one.  I was thinking of using one for a .22lr build, but I probably won't.

I was given a ati poly lower for free and am using it on a ultra light build I have, as a plinking rifle it has held up fine but won't trust it to my life as my first line rifle.

Good call. With the aluminum receiver, at least you'll be able to use it on your next 5.56 upper with no concerns.

GWAC is selling the Cavalier Mark II polymer lower..  I have heard very little negative things about it..

The Cav Mk II has an integrated buttstock - most of the other lowers take a standard buttstock and that is the weak point prone to breakage

And you Won't. We designed that lower with proper reinforcement. There was a reason the stock was integral to the design. We each had personal Full Auto lowers we used and would take to shoots and let others shoot away. I even parked my truck on one for pictures to shut some of the nay sayers up. I still have a lot of them in my personal collection. I have even shot my Beowulf upper on full auto with a Cav Lower. have a couple bug out KISS rifles built on Cav Arms lowers.

Had a PCF lower i used as an experiment on a lightweight build and it ran just fine for a plinker as the other guys have said on here though I wouldn't want to use it for something i'd be spending a lot of time with.

Polymer lowers are more of a "Good enough to get the job done" option. I have a ATI Omni lower and it is good to go.

However, forged lowers reign supreme compared to it's plastic cousins. So go ahead and buy a forged lower.






Also, to the naysayers. Quit shitting on a product and expecting it to actually surpass the performances of it's metal cousin. It's made out of plastic for Christ's sake!

How many rounds have you put through this lower?  How much actual use has it seen?

150 or so rounds, give or take 10. So far it has been to the range and back. Gonna put some more through it.



I was trying to say that it is a "Good enough" rifle, such as shooting at the range or for when you are in a spot of trouble etc etc.
It is not meant for long amounts of sustained fire or "punishing" uses like in a carbine class or so on.
(Just thought I would add that in to clarify what I consider good enough. Sorry if I caused any confusion.....)

i have seen the NFA poly ones used in full auto and have no problems. some people like plastic, some like metal.

I bought one right before Sandy Hook for like $30, IMO, they are not worth much more than that and I would not build one up as anything but a dedicated .22LR.  There are just too many cheap AL lowers out there for mess around with it.

I have two pre-raid CavArms MKII lowers.  It's a top notch product.

One of the MKII lowers lives on this AR.

I've got a Bushmaster Carbon 15 that I've put 800 rds thru with no problem. That said, I just finished a build with an Aero lower and PSA complete upper to have a REAL ar.

Happy owner of one original CavArms MKII and one new GWACS lower.  Both have been good to go, other than a tight fit of the takedown/pivot pins.  These are good, rugged lowers.

I would not buy any of the other poly stuff out there, due to the issues others have noted a million times already.
