We PDW Open Bolt Question: Not Shooting Hard Bullets Flopping
 

Hey Guys

OK so I just recently installed the Open Bolt System on my PDW and I'm not sure what the problem is but the bullets aren't shooting as hard as before.

When I had the Bras System installed it shot really hard. Now that I have the Open Bolt System installed its just shooting half that much not even.

My KWA USP45 shoots harder than this, I did a comparison. So I have a good feeling there's a problem somewhere.

Facts:
- Have not touched the Hop Up yet. I'm shooting this in my basement so its a pretty small, I don't think the hop up will affect the shots one bit.

- Cleaned Barrel before installing. Should be a smooth ride for the BBS

- Gun has been lubed up before shooting. Bolt moves smoothly

- Its not that cold in my basement. If it was the cold my USP45 would be affected.

- Magazines used is a brand new Open Bolt PDW and a converted M4. Weird thing is the converted M4 shoots much better.

- Propane Tank is close to empty but I used this on my USP 45 as well and it was fine.

- Full Auto more Floppy Bullets.

Anyone have any ideas on what I can do? Or what the problem is?

Thank you guys in advance :)

Cheers

When you changed from closed bolt to open bolt, am I correct to assume you changed out the hop unit and inner barrel as well? The open bolt hop up is different from the closed bolt.

yeah, try turning the hop up on

I turned down the hop up and it is shooting fine now. Not as hard as the Closed Bolt but its shooting better.

I never would have guessed because it was new and I didn't think the hop up would affect the shots like that.

Appreciate the post guys thanks :)
