54r Aluminum Mauser Stock Project

[Holescreek]

I've made a few aluminum stocks before but this is my current project and happen to have photos handy.

I have build threads detailing the build itself on a couple gun forums but I'll leave those details out because the management here doesn't seem to like us talking about the "bang" parts of gun builds.

This is a large ring 98 Mauser modified to shoot 7.62x54r. I've made a box mag but it's still in the R&D phase so I made some adjustments to the feed rails and can load and chamber 3 54r cartridges from the internal mag.

I started with a 2"x4"x 14" long block of 6061 and inletted it for the 98 action on a manual Bridgeport. The Mauser has a couple tapered areas that necessitated mounting the block on my rotary table and in some cases using a 3 degree tapered end mill.



Some clearance cuts for the bolt channel



and inletting at a 3.5 degree angle for the bottom metal.



Next problem was to figure out how to attach an AR pistol grip and transition it to the existing bottom metal. I created a joint behind the trigger guard to give me the transition:

Here is the inletting:

Very nice! I can't wait to see how this turns out. Would it be okay to post a test target after?

I'm trying out an idea using an adjustable ACE shock absorber in the butt stock, I needed a way to retain the shock to the butt pad and in the butt stock. The butt pad is dovetailed for vertical adjustment too:



Things happened kind of fast and I didn't get separate photos of the butt stock and I finished contouring the front and got the butt stock mounted:



I thought about making a folding stick but couldn't find a justification for needing one (going through the work to make a hinge) so I just made a modular attachment system so I could play around with different designs.

So here's where I'm at for the moment:





I just ordered scope bases and bedding compound, while I wait I'll work on a cheek piece, bipod mount, and try to come up with a paint scheme.

I've built a couple rifles in 54r for accuracy testing using surplus ammo. I've been on a quest for the claimed "M.O.A." that others on the net claim they are getting with it. This is just another attempt. I have just one more rifle planned in 54r but it's too early to get into the details.

Here was the last one:



and the one before that:

Getting closer... Still need to drill for scope mounts, bed the action, and do some reshaping on the end of the stock.
