Hey guys, I recently picked up a friends semi-new Echo 1 M28. He had succumb to the slam fire problem, and attempted to fix it with a new trigger box and sears set from ASGI. Installed it all correctly, but it still slam-fired.

Once i got it, I bought the new 300% Cylinder set from EHobby Asia and fully fixed the slam firing, but now Ive run into a new problem.

When i pull the bolt back, the first sears wont catch the metal piston. And with the brand new metal piston, i know it has to be the sears. I was wondering if anyone has had a similar problem and would know how to fix it?


And the other issue is that i recently bought 4 KS mags (same as the plastic E1 mags, except metal) and Ive been having a few feeding issues, where when I pull the bolt back, it will load 4-6 bbs into the area where the cylinder is. But it doesn't do it every time, just randomly. Any idea why it would do that?

Any help is appreciated, thanks guys.

Slam firing is only really solvable with a 90 degree mech or a lighter spring, or some fancy metal work. It sounds like the spring in the KS mags are too powerful or there is a flaw with the feed lips in general, which wouldn't be surprising.

So I would need a new 90 degree sears to fix it?

And I'll see if that's the issue, I'll let them sit and compress

You'd need a 90 degree mech to rid it completely. Look for signs of wear on the piston and piston sear.

Piston has paint chipped nothing more
Sears is defenatly worn, looks dipped almost at the tip.

Edit:

LOL!
Just opened up my trigger to check out the sears and it turns out that under the small pin that holds the first sear in place, the entire metal, ASGI reinforced sear was broken. huge crack running down it.

So, defenatly time for a new sear. I was told elsewhere a Deep Fire vsr would be good, is that 90 degree?

You can't buy a 90 degree sear set. Different mechanisms.

For this rifle you really don't need it to be shooting over 500 fps.

I had mine right at the 400 fps, and with some home mods I was able to get 220' very consistantly, and I didn't have an MED either


If you want man, send me the rifle, and I can do some work to it and get it shooting great, as well as looking great as well.

Shes already been painted beautifully, or so I think. But i wouldnt mind sending it to get her fixed up.
