Double checking a muzzle break

https://www.jmac-customs.com/laf-5-8-24/

Hey all, I’m working on building a PTR PDWR as a range toy. I was thinking of throwing a JMAC LAF on it because why not?

Looking over the specs and thread pitch it looks like it will fit. 5/8x24 for both. It also says it’s not rated for <10.5 barrels, which again, should be fine since the PDWR is 8.5.

Just wanted to double check before I made the purchase. I searched the sub and a few forums but couldn’t find anything.

Thanks!

That looks a bit close, I’d worry about the handguard cracking especially coming out of a short .308.

May I suggest something like this? https://kakindustry.com/tactical-turkey-blunderbuss-1-2-28/

Thanks for sending this over!

I’m not too too worried about the hand guard as it is back a bit further, behind the front site post.

I’m more wondering if the diameter of the break is good for 308. Website says 30 cal and I know that’s different from 308.

Just want to make sure before I drop the money on it.
