Locking piece?

My 33 and 53 run great suppressed with the #7 LP, no issues when I take the suppressor off either. I run a AAC M4-2000 on both. The 53 had ejection issues with the factory #15 LP when I put the suppressor on, which is why I swapped it, no issues on the 33 but it came to me with the 7 already installed so I just left it since it runs great.
 
This is my first 90-series silencer host. All my others are pistols, AR's, and my MP5-PDW.

Welcome to the site, and thanks for the information.

Had to tare them apart.
Looks like my Post-Sample German HK53 has a #3
and the SD we are running a #8, but may be re-ground

(Damn these things are dirty, guess you don't need to clean them until they STOP Functioning, RIGHT? )

Interesting muzzle device on the HK 53--- how is it attached? :unsure:

That was a No-Hair Special.
We had a FUN-SHOOT and the RO's were bitching about his Brake, so before the next shoot I had him make me a couple.
Feels like a .50 BMG when you stand beside the shooter, but there is absolutely NO Muzzle Rise on full-auto.

Real Simple, take a of 1 1/2" ID Steel tubing and a second piece of scrap and weld it to an HK Flashhider.
They are NOT adjustable so you can't index them to other hosts.

Funny, my wife and I were walking by the JP Booth at shot show when it was in Florida,
and I point and said "Hey Look, they copied No-Hairs Brake"

51K with about 10k threw it FA. They do erode some over time
