Compatibility

[Sustainable]

I have a complete 7.62 PSA rifle. Is it possible to use a 5.56 upper on the 7.62 lower. Wondering about the mag fit.

Yup. The lower is a multi cal that works fine with 5.56.

Not to contradict you... but I don't think you can use a .308 Lower on a 5.56 Upper.... the lower is a good bit longer (distance between take down pins).

I have both at home and can take a picture later.

I thought he was talking 7.62x39.

No, they're not compatible. Colt makes the 901 that can do this, but not aware of any others out there.

Oh- in that case, I could be wrong... Guess we need some caliber clarification @Sustainable

 

[Sustainable]

It is a 7.62x39

 

[karlvv]

It is a 7.62x39

Should work fine.

 

[Sustainable]

So the 556 mag will also fit the 762 lower?

Ah, disregard this then, thought you meant x51

Ditto... me too... I'll keep my bad advice to myself

Should fit like a glove.

I always think 7.62x39 first. I love mine. Plus I dont use nato commie speak for 308's.

Thanks for ALL the answers. Good to know about the x51 also.

Not being an AK person, I hear 7.62 and all I can think about is .308 Win.

My absurdity knows no bounds. I don't like commie ak's either. I like AR's that use badass rounds though.

Just to be clear, are you talking about the PSA AR47, or are you speaking of their KS47? If KS47, it's not compatible

This.

That seems self explainatory.

Meh, not really, he said it was a X39 rifle, did not say which one; just figured it would be best to verify rather than give inaccurate info in case he had the KS.
