PSA AR/AK Build Help Needed

[mouthpiece]

First determine if it is cycling enough to pick up a second round by loading 1 round in the mag and see DOES IT LOCK BACK?
What size is the gas port?
What buffer are you using?
There is nothing wrong with CPD mags or using an AR Lower with 7.62x39 AR CPD GEN 3 mags.
Love my 7.62x39 AR's
This can be a lengthy puzzle but it can be worked out.
I'll check back later.

I have 3 different mags.

So it is supposed to work on a regular ar15 lower?

What mags do you have?
CPD Gen 3 are the best.
Yes, reg AR lower

 

[mouthpiece]

So I do need a different receiver?

I really had no idea what I was doing and thought it was supposed to work with an AR15 lower

No.
It will work with regular AR lower.
I have several

Will shoot 1 round. Trying to charge it causes a jam, and I have to drop the mag and yank the charging handle every time. Just tryig to get this running. I forget what ammo. But When it fires, it fires fine. It's accurate

Can you cycle it without firing it?
What type of jam? Is it nosediving?double feed? Old case still in there? We need more info besides it jams

Usually double feed. I could never get it to cycle on it's own.
