    Non-reciprocating charging handle for M11/9?

    I have a side charging upper. I'd like to get the grey ghost charging handle for it if it would fit. Anyone know if it's possible to get just the charging mechanism fir one? I've seen Practical Solutions had something similar listed but I've never seen it in stock.

    What a coincidence. I finished CAD designing a drop in replacement for the MPA and USMG style uppers last night.

    You swap over your handle pieces. I wasn't intending to sell it, I was just making it for myself. I loaded it to shapeways and the 3 pieces would cost me $65 to make in steel. Can't have it CNC'd because they'd want a run of at least 100. Not really worth offering for sale as I couldn't mark it up much (if anything) and I don't really care to have cash tied up.

    I'm having a set of plastic pieces made up to double check fitment then I'll have them printed in steel. If it works out I'll let you know and might have another set made for you.

    So this would use a spring to keep the charging handle forward and out of the way? If so,I would be interested too. I have an mos side charger, that I would be wanting to do this to...

    Yes it has a spring and slider that wants to push the handle forward.

    Here’s a larger picture. The green plug at the back is pinned in place once the blue slider and spring are installed.


    The spring tube up top is canted to one side for clearance.

    Okay ordered sls nylon from Shapeways to make sure everything is perfect. No sense blowing $77 (actual cost) on steel which for some reason canít be even knicked with a file and destroys milling machine endmills. Not sure WTF kind of steel it is but itís atomic bomb proof. So if I want to adjust fitment Iíd have to buy brass (cost more) or aluminum (cost more still) or... just use nylon which is cheap ($17 shipped).

    The measurements are dead on as far as compared to the unit on my USMG upper. Ships to me July 19th. Iím excited.

    Did you check with Sam at Practical Solutions for the cost of the parts? Sam makes a similar unit. I had him convert a couple of side cocking uppers with his spring return units.

    I checked with him a few years ago as I already had the usmg upper and asked about the return. He didn’t sell it separate because it had to be fitted.

    I guess imitation is the best form of flattery. That looks a lot like what we have been making for ten years.

    Pretty cool. I’ve never seen a picture of yours sitting by itself. Didn’t notice a finger sitting behind the handle on any of your uppers. I just guessed yours was internal.

    Do you now offer just the parts to save me any further hassle?

    Yes. Let me know what style you need. Most uppers will require some fitting but the screw holes will all match up. You will need different mounting screws as well.

    Well damn! All that trouble for nothing. I took for granted what you said years ago was the same today.

    Curious to see what my nylon parts look like. Will get them and see if itís a direct drop in, which I trust they will be. If so Iíll just order them in steel and be done (and be proud I made my own). If not, well... guess Iíll ask you hat in hand.

    Sam, I am wanting the spring loaded charging handle piece for a MSA m11 side charging upper. Do I just need to call you to order the parts?

    To add content to this site... here's a quick update of my little project.


    So shapeways delivered along with stuff for another project I have going.

    Their sls printing in versatile plastic is very close to the dimensions sent. Much less shrinkage compared to my home FDM printer using co-polyester filament.

    The components. The blue tab I had to make a slight snip off the bottom to slide into the receiver. Turns out I made a slight mistake (oops) when creating the slot. This is exactly why I (and most others) print in plastic for testing.



    Aside from snipping the blue tab, everything fit together perfectly.



    The bolt holes like up perfectly although not bolted down yet.


    Lays flat (even without fasteners to hold the plastic straight) and the spring tube clearance worked out as planned.





    I robbed the fasteners from this spare upper to use on the one that's actually on the gun. Don't feel like taking the other apart at the moment for this quick look, but just pushing the spring by hand it pushes the cocking knob forward as planned. The spring needs to be trimmed for size and the rear plug installed but that's for another day.



    So what needs to be changed?
    1) fix the cutout so the blue tab doesn't need to be snipped.
    2) potentially use a softer spring, this one is fine but a bit overkill in strength by about 3 times.
    3) I undersized the blue tab 4 thousands for clearance inside the spring tube but may want to make it 8 thousands and try it. I'm thinking once it gets fouled with gunpowder residue etc the extra clearance will help as right now it slides but not sloppily as I feel would be best over time.

    To be continued...

    The one I bought from Sam worked perfect on my chopped (for a SWD m11a11) Masterpiece Arms side cocker.
