Suppressors Drilling out keymo flash hider to 3/4 24

[Brym427]

I would like to use the keymo flash hider on my 2 sr25s. Dead air hasn't made this yet, only the brake. Is there enough "meat" that I can drill out a 5/8 flash hider and tap for 3/4 and it be safe?

Have the barrel threaded. Suppressor mounting is best done perfectly.

Also, many of the muzzle devices are hardened as hard or harder than a drill bit.

There are a few other companies that make keymo mounts. I’d go look at them if you’re not happy with what Deadair offers. If and I mean big if you decided to modify one you’re going to want to have someone with a lathe bore it out and then threaded it.

You’ll run into a few issues.

1. The steel is very hard. Like The King said, you’ll have a helluva time machining it.

2. The SR25 relies on the muzzle face to seat the flash hider. You would need to ensure you start with a flash hider that already has that face cut so that you guarantee proper alignment. The DA302 5/8-24 is designed for shoulder seating and doesn’t have the precision face for the muzzle seating. DA305 7.62 SCAR flash hider does, though.

3. There needs to be enough meat in there to machine new threads, so the major diameter of the one you start with needs to less than the minor of the 3/4-24 (.705”).

I hope that helps!

Why not do this?

I'm hoping to put flash hiders on my 2 sr25s a awsm and axsr. I don't care about changing the barrel on the new AI but the rest of the guns I would like to keep factory for value purpose

Oh yeah it's definitely going to be bored out and threaded on a lathe. Very carefully!

Temporarily out of stock, but they do make them...

Did you check jmac? They make all sorts of odd ball keymo flash hiders.
