Rifle Scopes Steel or Aluminum Rings?

Re: Steel or Aluminum Rings?

If you use an aluminum scope body you want aluminum rings so long as they are from a quality manufacturer so you have no concerns of weakness. Either will work though really. Same with the base. Steel would be ideal since the action is steel but either would work if from a quality machine shop.
 
Re: Steel or Aluminum Rings?

i have Badger Ordinance marine corps 30mm rings[which are steel] excellent quality but very heavy and my guns are already on the fat side[Accuracy Int. and a Sako TRG22].I have a set of Seekins on my TRG [aluminum]34mm.also excellent quality but much,much lighter.if weight is a concern i would get the aluminum.i would love to swap them out for a set of Seekins

The better quality aluminium such as the 7075 are as good as lower grades of steel, but much easyer to machine and much cheaper.
Weight of alu is about a 1 /3 of steel.

I use steel rings from traditional guns where the traditional looks are important, and alu for modern solutions where the possitiblitys are important

Here are my .358 Norma, my main hunting rifle, a typical example of where I prefer steel rings. The rings here are from Recknagel and Apel, and it is a swing mount.

On a modern gun for different use I prefer a modern mount, such as my own mount here. There is also much other possibilitys in alu. To produce this mount in steel or even worse titanium would rise the production costs with 3-4 times, at least.

Re: Steel or Aluminum Rings?

The explanation about steel for bigger calibers and alu for weaker calibers doesnt hold up well.
There is steel qualitys that are less good than the best alu qualitys, as well as there is manufactured extremely poor alu items as well.

For rings, there is a number of good manufacturers that is fine for .50 BMG as well.

Generally spoken the best aluminium are very difficult to extrude, and thus very expensive to extrude and there is also a lot of things that cant be extruded in a high quality aluminium as there can with a low grade alu.
Therefor to keep the costs low many companys who extrude their products uses lower grade alu-alloys for that.

Re: Steel or Aluminum Rings?

Aluminum is quite a bit easier to machine, and is much easier on tooling than steel. All things being equal, manufacturers will be able to hold better tolerances, and produce rings faster if they make them out of aluminum. (I'm talking about milling / turning from solid. Extruded rings are generally of quite a bit lower quality / softer aluminum.) What this means from a practical point of view, is that they can either offer aluminum rings cheaper, or hold higher quality for the same price as steel.

At Murphy Precision, we've gone to the other extreme -- We make rings out of stainless steel or titanium. We Wire EDM the ring bodies out of 3/4" plate. This takes maybe ten or fifteen times longer than it would take to mill them out of aluminum, but it offers unmatched accuracy. We are able to hold .0002" tolerances on the ring diameter, and better than .0001" parallelism between the bore and the Picatinny mounting surfaces, since they are cut at the same time, in the same setup. What this means is that as long as your Picatinny rail is straight, and un-stressed, there is no need to lap your rings for a near perfect fit.
