I'm having trouble on semi auto non forced reset mode where the arm on the bssquirts ARSS15 drop in FRT that I'm using drops in front of the hammer and prevents the charging handle from being pulled back. It does this with my G$ SSA and S3G using the overtravel device. I've also tried a few different mil spec triggers that I had the same problem with.

It's also the only frt I've used that needs a extra power spring and a H3 buffer to stop bolt bounce.
I contacted Shawn from bs squirts and asked him why the arm was falling in front of the hammer and asked how to fix it. I was told there's nothing wrong with it. Sometimes that just happens.
I was wondering if anyone else has had this problem with the arm falling in front of the hammer in semi and how I can tune it so this stops happening?

The picture on their website shows it behind the hammer - above the safety. Below to where the cutout is on the upper receiver.

When in fire mode - the safety should allow it to pivot backwards - allowing the charging handle to be pulled back to charge the rifle.

Does it rotate backwards out of the rifle?

Yes it moves freely out of the rifle.

I think you may need a different blocker.  Sent you a PM.
