M5 Mausingfield .223 function

[7mmSTW]

It was mentioned in the ARC thread but I thought I would ask separately. How many have tried the .378” bolt head? Someone mentioned their m5 ran good with .223, just wondering if this is the exception rather than the rule? I know there is a Disclaimer on the ARC site stating it may not reliably eject. Just thought I’d see how many here have actually tried it?

Thanks!

Bump for anyone running this setup. I’m interested, too.

Just receiced my bolt head in the mail after someone on the previous forum said it works without issues. Still have to order a xylo and send to lri for full build. So i wont have feedback for a while lol. I hope no one posts negative issues, would suck to have spent all that money for nothin
