*POLL* The Poverty Pony vs. The Colt Cult: Is it REALLY worth the extra cash?

[cmshoot]

It’s a lower . Let’s have a show of hands ?

How many have had a lower completely fail ?

Anybody ? Mag fell out and the stuff just gave out

In a gun I’ve owned, built, or was issued.......never. I have seen what I would call catastrophic failures in lowers belonging to students.

Looking at those tensile strengths, according to my math, 7075 is closer to a 90% increase in tensile strength. I would imagine those numbers could differ slightly from source to source, though.

Colt lowers cost a lot mostly because of cloners, people who recreate military rifles. There are plenty of lowers as good as Colt.

Anderson lowers probably have the largest number of spec issues of every manufacturer you've heard of. Assuming it's in spec, the anodizing is thin and there's zero flare to the magwell. If you're a cheap bastard, buy an Aero .

General Mechanical Properties of 6061 Aluminum (T651 Bare)
Tensile Strength – 45,000 psi
Yield Point – 40,000 psi
Brinell Hardness – 95
Elongation at Break – 12%
Shear Strength – 31,000 psi
Thermal Conductivity – 170 W/m-K
Strength to Weight Ratio: 115 kN-m/kg

General Mechanical Properties of 7075 Aluminum (T651)
Tensile Strength – 83,000 psi
Yield Point – 74,000 psi
Brinell Hardness – 150
Elongation at Break – 10%
Shear Strength – 48,000 psi
Thermal Conductivity – 130 W/m-K
Strength to Weight Ratio: 196 kN-m/kg

Pretty much this but also 7075 to T6 hardness is mil spec. 6061 has more zinc which makes it easier to work with as far as welding is concerned but 7075 is desired for it's strength properties over 6061 even though it is harder to work with. On a forging I can't see where welding would come into play since the alloy is forged to a rough shape and then milled. There is no welding required. You can obviously see the difference are in favor of the 7075 in the chart above. It's much stronger all the way around. You can see why 7075 would be desired for a mil spec part.

And to hell with polymer anything. I want carbon steel, or stainless all the way every day.

I’ve built more AR rifles than I care to remember . I still have two left . Both Anderson lowers . If the hole is a little off then correct it . It happens . I get wanting a nice product but having a nice product but I’ve yet to see the magic that colt has on their anything . It’s the same crap .

That 70% ain’t a number that I made up off the top of my head. It’s a fact and it’s known in the industry. I used to do quite a bit of work in a buddy’s shop who is a Master Machinist, as well as a tool and die maker. Big difference between working the two. If you hacksawed a 7075 receiver in half, and did the same with a 6061, you could tell the difference without someone telling you which was which.

6061 is cheaper to produce. Also, it’s is softer and easier to machine, so you can knock them out quicker and cutters wear out less. Cutters wearing out less means you use less of them and have less down time replacing them. So, a manufacturer can produce a much cheaper receiver because they save money several different ways. Problem is, manufacturers that use 6061 are using it BECAUSE it’s cheaper, and they tend to cut corners in other ways as well. This can include looser tolerances, batch testing for QC, less durable/expensive finish, etc. it’s not usually just a difference in the aluminum used from one to another, it usually ends up being much worse.

There are companies that use 7075 that also cut corners and turn out a shoddy product.

It looks like Greg agrees with the data you posted so I agree with it also.

I apologize for questioning your numbers. I just really didn’t know that there was that big of a strength difference.

I admit that I’ve still got a LOT to learn about the AR platform, but with Greg in my corner I know I’ll be a champion one day.
