I was wondering why the stripper clip grooves were still there. Also why leave the recessed notches near the rear of the receiver on the sides?

I'm thinking about a barrel block setup. Totally unsupported receiver like in some of the heavy weights.Here are a couple of pictures that are giving me ideas.

I like the idea of a 2 piece break down rifle, makes it easier to buy a case for.

I like the receiver except for the picatinny rail. It needs a dovetail setup like the SV98 so you can release the locks and slide it of the rear. That type setup has full side rails that clamp the mount instead of 2 small clamps. It would also cost less to manufacture. I like the double recoil lugs. It would be very stable once bedded.

Ben is the barrel thread going to be longer?

I will be getting rid of those soon. By the way you can download 91/30 CAD models off of 7.62.net for free. It's actually what I am stating with.

I will take most of the notches out.
The barrel will thread in by almost 2 inches. I don't think I will use a barrel block it's going to ad to much weight. Maybe another build I will.

With a beefed receiver and 32" barrel you're already going to have a 14 pound rifle. Might as well go for the barrel block if it helps accuracy.

Here is the receiver I am designing. Still have tones of work to do on it before it ready for the CNC machine but thought I would share.

I have filled in most of the lightening cuts and stripper clip notches. Made the recoil lugs square. Also started to Hex the front end to ad metal there. The hole thing shouldn't be to much heavier then a regular receiver. I am expecting only about a 1lb increase or there a bouts.

I am axing the barrel block idea.
This receiver will have almost 2in of threads for the barrel to bite. Intagrated pic rail. After I finish the receiver I have to design a bolt and rig all the joints so it can be animated. Before I send it to the CNC machine I want to at least see if it will work in the computer ;D

Have you figured a way to use more then 60% of the locking lugs?

Joe: I sent you the CAD files.


Jerry it just a simple matter of shortening the lug ramps. Really quit easy ;)
