So I had a little fun with the MR1 over the weekend.

Finally got around to making the second part of this video where I finish the brackets for this rocket fin assembly!

looks great. Only problem is the is your barrel is no longer a “free floating barrel” and the free floating hand guard doesn’t do its job anymore. This is why your suposed to rest the gun or support the gun on the free float hand guard. 
To achieve maximum accuracy the barrel needs to be free floating and not touching anything during firing. This is why bi-pods are mounted to the stock and not the barrel on sniper riffles. The closer you get to the end of the barrel the worse the effect will be.
If you ever fire a hunting rifle you never rest the gun on the barrel but always support it with the stock.

Ya i know about barrel harmonics, this i for replica colt 741/941 rifles. This ar15 is the only one i have in 5/8x24 to show it and i didnt want to dig through my box of spare parts to see if i have an adapter. If you want i can post a pic with my replica m16a1 or my colt A2

Dang, it does look super badass! I totally agree not all guns need to be precision. I just wasn’t sure if you were aware of barrel harmonics aspect or what you were “aiming” to achieve. lol I have an ar pistol that is crazy fun to shoot (and looks badass). It’s not the most practical one I have but it falls into the “I love it and it’s mine” category. It has a piston upper so with super heavy for a pistol but I still love it.

What do you make with the injection molding machine. This is really awesome 
If I had a means of milling, I’d probably make more clone-correct specific parts that are impossible to come by.
Maybe even get into other items like night vision.
For example one of my housings is easily over a grand and it’s made of 7075 aluminum.
A complete setup depending on the tubes is an easy $9k.
The monocular on the left is also milled out of 7075 aluminum and that’s just under $5k alone.

Ya NGV stuff is crazy expensive. I have some thermal stuff but no true image intensifiers. Also the market is questionable, lot of people dont have them because of how expensive it is. But ya know you can always get an MR1 and start making them!

Just have to be in the right groups as I know some people easily spending some $19k to upwards of over $30k in just night vision.
No way I’ve got room for a mill though lol I’ve got a small as hell garage.
Just cool seeing the stuff a lot of guys here are making.
Ran a batch of steel tracking devices for the BA Shredder (2x72 belt grinder)

This is my first time posting on the forum but picked up a used MR1 a few months back and finally got around to making an actual thing! I am new to 3-axis machining but luckily have some familiarity with Fusion 360. Whipped up a custom card holder and spent a few hours programming. Watching this machine work is pretty mesmerizing!

James! This is your inner child speaking. Buy one… right away… you’re running out of time.
I’m 63 and I just bought a lightly used MR-1 about two months ago. And I’m as giddy as a school boy. I’ve wanted a CNC mill for over a decade but I couldn’t justify the cost and all the machines were industrial class – so they would fill up half my shop… while draining half my bank account. The MR-1 was the solution. Top of the hobby class, bottom of the industrial class. I could care less what my family does with it if they out live me. Love your idea of willing it to a maker space.
If you want an MR-1 bad enough to hangout on an MR-1 support forum, then clean out your shop and just get one. Life is too short. And that maker space will honor your memory with a custom engraved plaque that they make with your MR-1. In fact, put that as a condition in your will that they don’t get the machine unless they make the plaque. 
@TurkeyLeg Hey Adam, this is great! I just got the same chuck delivered a few days ago. I’ve just been pinching to the bed with one bolt anchored to the plate plus three clamps for now; but what I really want is a fixture plate just like what you built. I can’t believe I’m gonna come up with a better design than yours so if you’re up for sharing your CAD file I’d be grateful.
Cheers,
Bob
No prob, when I get home Ill dig up the file and get it to you!
Thanks, Adam!
