Making modelguns work

Hi all,

I have seven or eight modelguns and only two of them works perfectly : JASG S&W M10 and my Tanaka Glock 17. I have a project to make a short movie in the coming months and I need those modelguns to work. I will update this topic regularly.

I will start with the Hudson AK-47 : it was a second hand I bought last year. I barely used it, just test it with two old but original carts last year. 8ace was able to provide new carts  

Problem 1 : not solved
I can't load 30 rounds. The tension is too high. Carts get stucked. I have noticed that it is deformed a little bit. Or is it normal ? The more carts I load, the more force I have to put to remove a cart from the magazine.





I have also noticed that this deformed part will block the carts when they will be chambered.



I have noticed as welll a gap in the magazine.
Maybe this is normal ?



Problem 2 : solved
When a cart is chambered, it will get stuck inside. Each time I have to dismantle everything and remove it with a pincer. This is definitively not normal.



Edit : I found the origin of the problem. The detonator pin is damaged and creates irregularity that will block the tips of the carts. I have another problem with some of the tips of my custom carts. They will not fit the detonator pin at all but it will be fix thanks to 8ace.



Problem 3 : not solved
Handguard is moving but I don't think it is a bigdeal.

==========

Next modelgun, Marushin S&W M39 : Bought here one or two year ago. It was sold with weird carts but definitively not genuine. Shazhib was able to provide me 15x original PFC.

Problem 1 : solved
Carts always get stucked in the chamber. I have to remove it with a pincer.



Edit : I removed the detonator pin and found out that when you insert it into the top of a cart, it will touch and make friction. So I reduced very slightly the diameter of the detonator pin. Now it will insert more smoothly.



Problem 2 : not solved
Carts will jam when loading. When making a dry cycling without caps, carts will eject most of the time correctly but sometimes it will jam.



Problem 3 : not solved
I have noticed that the cart on top of the magazine is never straight.
It should be parallel with the other carts isn't it ?



Next coming soon...

AK-47 problem 2 solved
Is there anyone here who can post some pics of his/her ak-47 mag (top only) than I can compare with mine ?

I thought I had one somewhere, here you go.

Thanks for the pics 8ace
Looks like there is no problem with my AK mag.

Although the mags look similar it might still be causing problems as small difference can mean a working/not working model. So do discount it completely.
