I have the kit from GS. Works well with plastic magazines. There is some seating "slop" , so I always make sure the mags are up a certain way so as to negate the theororetical chance of a misfeed.
No misfeeds yet.
My metal 1980's era mags have had issues. Mainly last round not hoding open.
I wish the GS kit was made of metal, or maybe a metal like polymer, because GS instructions say metal mags may wear down the GS kit over time.
Which plastic mags are you using please Zuper?
Our conversion kits are anodized aluminum if that helps: https://store.theshootingcentre.com...g-conversion-kit-for-famae-sg540-1m-sg543-1m/
