Anderson lower questions.

[rabidravens]

I am considering purchasing an Anderson lower from one of the various IP that is offering them. Does anyone have any experience with their lowers? I have never heard of them until recently.

I have several and have seen no problems with any of mine.
Fit and finish were excellent with mine.

Never heard of Anderson's Lowers, is like never hearing of Colt. They are great! Several online websites have them for around $50 to $75.

I have a lower and upper on a build I did. I like them alot and they look great.

Gotta have some fun...there's Lowers I never heard of. Especially when you doing research in who makes them.

i have one of their no f/a, no port door uppers coming sometime soon. ups claims delivery should happen tomorrow, which as we all know means i'll have door tags left while i'm ducking home (i got yelled at for naughty language so i'm using non-naughty words that you all understand) without a doorbell ring or a knock for a week, with them claiming they can't hold it for pickup because it's already back out on the truck.

but yeah, i should have it soonish.

lightweight build. going for under 6. shouldn't be too much of a problem.

I have several Anderson lowers. The fit and finish is terrific. I would, and probably will, buy more.

I did my first AR build on an Anderson lower. The. Cmmg lower parts kit and upper fit perfectly with with no wobbles.

How do the Andersons compare with Spikes? Thanks..

 

[armed ferret]

Upper is a cerro forge (keyhole mark). Wouldn't surprise me if the lowers also come from cerro.

Which means they're GTG.

Describe what you mean by "compare" to Spike's. Because really the only difference is the Anderson doesn't have dueling penises for a logo, and costs half as much.

The Anderson lowers i am waiting to pick up had the cerro forge (keyhole mark).

 

[armed ferret]

There's plenty of in-service mk18s out there with cerro forge uppers. I'd say there's nothing to worry about.

Consensus is that most of the forged lowers are made by the same company then stamped with company's names. IIRC PSA, Spikes, Anderson, and Seekins along with a few more are all made by the same company. Someone correct me if I am off base.

Sort of right, sort of wrong.

There are several forging houses out there, but all are GTG.

Not all of these are still in operation, but many are.

A (splintered) = Anchor Harvey Aluminum
AF = Alcoa Forge
C AF = Colt Alco Forge
C MB = Colt / Mueller Brass
Cardinal (stylized) = Cardinal Forge
CH = Colt Harvey Aluminum
Circle/Crosshairs w/"AR" = ArmaLite
CK = Colt / Kaiser Aluminum
CM = Colt / Martin Marietta
D (stylized) = Diemaco
DK = Diemaco / Kaiser Aluminum
E = Emco
EK = EMCO/Kaiser
E MB = EMCO/Mueller Brass
F keyhole = FNMI / Cerro Forge
FA = FNMI / Anchor Harvey
FK = FNMI / Kaiser Aluminum
FM = FN/Martin Marietta
FMB = FNMI / Mueller Brass
Keyhole = Cerro Forge
L = Lewis Machine & Tool
LK = LAR / Kaiser Aluminum
LM = LAR / Martin Marietta
M (under diamond) = Mueller Industries
PA = Capco / Anchor Harvey
PM = Capco / Martin Marietta

Well to use your words: "Sort of right, sort of wrong."

Cerro is a forge that makes the forging. So the outer dimensions and material peoperties are just as good in one as the other. But you still have to machine all the insides out. Anderson has a bunch of CNC machines so likely do their own. Places like Aero Precision machine lowers for other companies (IIRC they are a large machining business w/ firearms boing only a small part of their operations.)

W/ machining it there are still quality checks involved. How often to they replace worn tooling, how good are the fixtures, QC checks, etc. So just because a lower has a cerro stamp doesn't mean its similar quality as a another companies w/ the same stamp.

Fair 'nuff.

Speaking of machining...

Kinda swamped for a few days but I'll be in touch.
