Are they durable enough for SHTF considerations?

Any known problems with them?


UPDATE

The lower was pare of a trade I was working on. In the end the guy decided he didn't feel comfortable with the deal. I was offered a colt lower instead by the next person and made the deal.

Pyro 6988: If you want to try one of the Cav lowers, I have an OD green one, Armalite lower parts kit, only used with a DPMS .22 upper, $200 shipped.
If interested, e-mail trex38@hot.rr.com. Delete, has been sold.

The best deal going seems to be the CavArms lower sold by Armalite (Eagle Poly-15). $165 including the lower parts kit and buffer. Too bad Armalite is so damn hard to contact and get decent customer service from.

I would buy one simply for the light weight if they made one with a shorter stock.

Depends on what you consider SHTF.

I'm seriously considering using one of their lowers on my HD rifle.

But in a situation where I wouldn't have access to my other weapons, and a limited supply of spare parts, I would rather have an aluminum lower just for ease of repairing replacing parts.

I have CAV rifles and would buy more.

Shorter than what?
The MKII has an A1 length stock.

Thanks for the offer but I am considering a trade for one with another member.

I'm happy with mine, never had any sort of malfunctions or problems with it. Now, Im not sure how super durable they are, I've never tested an aluminum and polymer lower side by side in some torture test. But, I've never thought my lower felt flimsy nor had it break.


If you want to fuck with it and see what it takes to break one, I think its like a 30 dollar replacement fee under their warranty.


I think the only 'problem' with them is you can't put all sorts of neat stocks and grips. My wallet likes that feature though


The ergo's are great stock as it is. The only modification I've done is put a Houge Hand-All (Small IIRC) on. It gave the grip a little palm swell and some finger grooves.

I'm interested in the CAV Mk II also. Just a little concerned the mag well is so wide (for double stack M3 45 mags). Do 5.56 mags hold securely or do they wobble/wiggle around in such a wide mag well?

Thanks

It's only wide in the middle. Front and back are normal size, so the mag feels no different than it would in a 'normal' mag well.

Lots of people voting for Aluminum, but not many posts to that effect.

I've got one I have been using off and on with a .50 Beowulf upper, no problems. I like the ergos, weight, and the cost is great too. I plan on getting more.

I wouldn't trade mine for an Aluminum.

Whoever said stick with aluminum should explain themselves.

I believe they would be a lot better without the furniture attached to them.

It limits your options.

The stock and pistol grip are part of what makes it so strong.
The other "plastic" lowers, aren't as durable as the Cav lower.

Every time somebody suggests a telescoping version they say that making that work would negate the advantages of being polymer. If you need the options, get an aluminum lower.



Are they durable enough for SHTF considerations?

The only broken lower I can recall was a .45 that cracked from the bolt hitting it because the buffer was too light. I'd consider it durable enough for SHTF, but if your scenario includes limited access to spare parts you might want to stick to an aluminum one.


Any known problems with them?

Mine was an extremely tight fit on my uppers. In fact, I sent it back because I couldn't get any of my three uppers to fit. They said it fit all of theirs and sent it back. When I got it back I could just barely get mine to go on. Apparently the tight fit it typical. And that's not necessarily a bad thing.

The pistol grip shape is different from a regular AR, which you may or may not like. The distance from the back of the grip to the trigger is longer, which IMHO feels nicer, but the reach to the safety and mag release are also longer. I can just barely reach them, so if you have short fingers you might have trouble.

The only functional "problem" I've had is that 20-round mags are hit-or-miss on dropping free. The CavArms lower doesn't have the groove at the front of the mag well for the rivets on the front of the 20s, which I think is why they hang up. The 30s don't have the rivets and usually drop free.
