Seems to be some conflicting info out there about minimum barrel length for 5.56. Most sites (like SS) say 10.5” but I’ve also read it’s 7.5” for 5.56 and 10.5” is the min for 6mm.

I have a Polo K and it’s 7.5”, so I would hope the Void is gtg on a 10.3” since it’s essentially a Gen 2 Polonium.

I realize we’re taking about 1/5 of an inch, but I want to be right.

Any experience or thoughts?

Guarantee it’s good for 10.3 if it’s good for 10.5. I’m guessing 7.5 is probably like a “it won’t blow up, but don’t expect to get a ton of life on it if you run it hard”.

Yeah I know it’s almost a ridiculous question, but it bugs my OCD.

If it's truly like the polonium, 7.5 on 5.56

Alright so
Minimum barrel length restrictions are basically just what the manufacturer is willing to warranty at the end of the day. Which is this case is technically canik, as they decide what is/isn’t covered under warranty

Having said that we gave them recommendations on what to make the restrictions and they didn’t listen lol

What we recommended was shorter than what they published.

They’ll take more than they’re listed for but take that for what it’s worth

There’s limits to everything though. Had a dude blow one up on a 8” barrel 308 and it’s like yea dumbass that’s 36% shorter than recommended. It’s not like a small amount lol

Just use common sense and it’ll be fine

That won’t be an issue. I don’t mag dump or shoot crazy amounts of ammo.

I also have a Polo K, so while it (the Void) will spend some time on the 10.3”, it will spend more on longer barrels. I’m planning on building out an 11.5” anyway.

Again, appreciate the response and your company!
