All steel AR-15 receivers?

[River Jack]

Looking for an all steel (not aluminum) milspec AR-15 receiver. Anyone know where to get one?

[OCMI_Teddy]

I think DPMS used to make a few, why would you want a steel lower?

If it's milspec, it's not steel.

Uh......why?

Completed with steel pistol grip and steel buttstock? I've never seen one in person.

Boris the bulletdodger says "Heavy is good. Heavy is reliable."

Seriously, have you worn out an aluminum AR yet?

[tiger222]

There was a company making stainless lowers - can't remember the name, sorry. The only reason I could forsee using one is for 50cal- ish use....

[popeye4]

Uh......why?

"Milspec" stands for "Military Specification". That specification calls for a specific alloy of aluminum (T7075, I believe) manufactured to a specific method (forging).

The lower is a case for the trigger group and a holder for the magazine. You get absolutely no benefit from making it out of steel.

this.

AFAIK, No AR-15 receiver is mil-spec, since the Military never spec'ed out a semi-auto recevier. So, what most manufacturers do is make it as close to the mil-spec as possible with regards to forgings, materials, finish, etc, and then machine it as close to M-16 specs as possible, with the exception of the full-auto stuff.

you benefit if you want a stronger or heaver "case".

I want a steel lower so I can put my refrigerator magnets on it.

...you benefit if you want a stronger or heaver "case".

I think with AR15 lowers, harder is better than stronger. But yeah, anything can be a benefit if you want it. A case of "crabs" would be a benifit to me if I wanted to get more practice scratching my crotch.

The heavier the gun the more accurate and reliable it is right?

Heavier guns tend to make shooters more accurate. The weight of the gun doesn't affect ballistics, unless that weight is adding to barrel rigidity.

The reason I want to purchase an all steel AR-15 lower receiver is because I'm looking for a the perfect match for my lonely Bohica MK-III .50dtc upper. I know just about any off-list AR-15 lower will work, however have heard/read that eventually (after perhaps hundreds/thousands of rounds) that the pressure placed on the pins by the heavier recoil of the .50 cal. can result in the eventual stretching/loosening of the pin holes, which in turn results in a ruined hunk of aluminum that won't work for anything but a cool-looking parper weight. A steel lower would not likely be subject to this warpage.

And, ok, maybe steel technically isn't milspec, but I need a lower that is as close to the same specifications as any other standard allegedly milspec lower (some, not quite milspec lowers apparently don't fit too well).

And, yes, steel is heavier (at least a few ounces) and therefore will help reduce recoil (another plus).

So, are there any out there that are off list that I can obtain?

[rabagley]

The only non-alumium, non-bronze receiver that I know of is made by DPMS, and that's on-list.

I'd find an 80% bronze casting and complete it. Be careful to stay away from ar15plus.com
