Armbrust-Tuning mit 10 Schuss-Magazin - Steambow M10 Upper - Vorstellung und Montageanleitung
Today, Crosby Action World would like to show you the installation of the new Steamboat M10 upper.
Here we have the main body, the upper itself.
Here we have a lower picatinny rail and an upper one.
By removing the side picatinny rail, I can then pull the upper one forward.
There is a light cone in the upper one.
Then we have the rear sight. This is also interchangeable with another one.
Depending on the distance you want to shoot, you can choose accordingly.
We have a belt buckle for a one-point belt.
That means I can hang my arm around my chest.
We also have a dry fire safety.
When I push forward, it is secured accordingly.
When I pull back, it is free to shoot.
And we have the AR-15 pin to open or close the upper accordingly.
That would be quick to the upper, to the main body.
We also have a mounting block for the AR-15 pin.
And we have the 10-shot magazine accordingly.
First, I have to remove the rear Allen screw or Allen screw for the magazine.
Then we remove the bow, because it is easier to mount.
As you can see, we also have the right color for the color kit.
By the way, we also have that for all other color kits.
Then we need a 7 mm ring or mouse key and a 3 mm Allen key
to remove the front axle or Allen screw.
We have already pre-mounted the whole thing a little bit so that it goes faster.
And we take the magazine off.
Next, as I said, the mounting block is placed here in the back,
where the Allen screw or Allen screw used to be.
We then fasten the whole thing with an Allen screw
and need a 2.5 mm Allen key for this.
Then we take the upper and put it back on,
where we prefer to take off the belt bracket.
It just mounts better if nothing wobbles around.
We pull out the AR-15 pin here and then put the upper back on
to fix it here with the AR-15 pin.
As I said, we have a long hole here.
We need this to adjust how strong or how easy the pin can be pulled.
If we push the whole thing backwards when mounting the front axle,
then it is easier.
If we push the whole thing forward a bit, it is not much,
you can hardly see it here or not at all.
But it is quite noticeable.
Then the whole thing is more difficult.
Everyone has to find the right variant in the adjustment.
So we put the axle or Allen screw back in here,
the corresponding opposite washer and self-locking nut,
and then tighten the whole thing accordingly.
And as I said, if we push backwards,
the AR-15 pin goes in and out more easily.
However, you should not get the idea of greasing this one,
because it could be too easy and that I would damage it.
