Home Forums Hunting & Shooting Hunting Rifles Details wanted on Ruger American magazine lengths

It kinda looks like a diaphragm.

Alright, I'm sold. I want some now, and I don't even have an American yet

But it works in the opposite premise Billy. This one lets things in, instead of keeping things out.

Ha!

This is pretty cool. Will make for a really useful rifle.

Does it work?

It needs a few dimensions tweaked to work perfectly. 1st prototype. I really need some feedback on what would be the longest cartridge so I know how far to set back the rear wall.

Master Cam (I'm assuming that's what you are using) is pretty cool. Shouldn't be too hard to work something up. Get a patent on the SOB and then when Ruger gets their chit together, they will have to pay you

+ 1...could turn out to be a real money maker

So......how good are these Americans shooting?
Guessing pretty good to be worth the trouble?
Shooting great out of the box...no tricks?

Here is my 223 American at 200 YARDS. Not too shabby for a $331 rifle.

First group after mounting a different scope...



I took to a few clicks down...



I moved it a few clicks to the right, pulled the target stand and painted the 200 yard gong. I waited for the wind to die a little to confirm zero....



Two clicks to the right and I then fired this 5 shot 200 yard group on the same gong. I'm impressed with the rifle....and the other American 243's I've owned too.
One inch groups (and below) at 200 make me happy.

I'm anxiously awaiting the SS compacts.

Wow...looks great.
Isn't their claim to fame some v shaped bedding blocks?
Apparently they work!

cotis - any update on the mag mod? Looking at getting a SS 223 and your mod is very interesting.

Anyone considered filling in the "flutes" in the back of the factory mag with devcon or marine tex, and then increasing the depth of the slot for the shells to allow a longer coal. Seems like a steady hand and a dremel could yield similar results as the new back end.

I am still working on the mod, but have been delayed a week due to heavy demands at my real, paying job! The design is basically complete, ShortActionSmoker was testing the first prototypes. I need to make a few tweaks and run another one or two prototpyes for testing. The funny thing is that I don't own one of these guns in .223! Makes it hard for me to test. I am working on solving the production of them now. Full blown injection molds cost thousands so I am looking for a more economical solution. I have ideas on this...

My 1st thought was the same as above, fill in the rear and machine a deeper slot. I do believe this will work but it is not a viable production solution.

Cotis nailed it!!

Fedex dropped the new rear portion of the mag today. I couldn't wait, I had to try it immediately. Put it on a mag and started sticking cartridges in.

The 75 A-Max pictured below measures 2.429". These are into the lands .010". 5 in, 5 out. Not a hitch....

This takes the RAR to another level!

Awesome...put me down for 2

Super cool! Just wish they made a lefty...if so my son'd have one.

Looks good to me, I'll take a few myself when they are in production..

Here is an update on the manufacture of these. They will be injection molded just like the factory. I am building a small-scale injection molding machine to do this. I COULD USE SOME HELP ON A FEW PARTS! I need a metal block or cylinder about 6 to 9" with a large diameter hole down the center. This will become the melting chamber that the ram will push through to inject the melted plastic. Please PM me if you can help as this is the part I need the most help sourcing!

A buddy called me yesterday and told me about an old PVC business that was shutting down and selling stuff off. I ran up there and picked up some things for a song. Specifically this:


I will modify and add to this machine, but it is a great foundation for what I want to build.

I also need a PID temperature controller with thermocouple if someone has one laying around. They look like this:


I can pick one of these up for ~ $30, but if you have one laying around I'd love to swap you some finished mag parts for it!

I am working hard to get the mold made, this is the most difficult part of this endeavor. Several of you have PM'ed me with questions and requests to purchase. I appreciate the support and feedback, please keep them coming.
