Best New Design Silencer For HK53?

[Galil#1]

For a real Pre May/Dealer Sample HK53 (made in 1983) please include the muzzle device mount info used too please! Thank you everyone!

Surefire Socom 556 expensive but built like a tank..

I have the surefire socom 5.56 it's really heavy and ultra gassy on ARs and even my scar 16s. I would look to get something with less back pressure. It does however have the best sound of any 5.56 can I've tried

No one with a suppressed HK53?

I think the barrel is too short. SOCOM 556 is meant for 10” and up.

^^^^ Herd that too... at 8.3" bbl not easy to run well... just hope someone has success at a workaround etc.

I bought a Saker 556k to run on the 53, but I never got around to running it suppressed. Life and other projects got in the way, so I can't comment on how well it runs.

^^^^ Nice... what muzzle device would be needed for it? Thanks for replying.

A lot of people use muzzle brakes as sacrificial blast baffles to help protect the actual blast baffle of the suppressor. Since the muzzle brake isn’t a registered part (nor welded into the silencer), you can replace it easily as it nears failure.

I’ve never suppressed a HK53, but a Huxwrx Flow 556k might be worth looking into for several reasons:
1) no barrel length restrictions;
2) extremely low back pressure;
3) has features to make it self-tighten during use which might be helpful for full auto strings;
4) it has been tested to pass 6 cycles of “SOCOM Reliability Stress Test,” which seemingly refers to the SURG testing protocol; and
5) it uses a folded-path design without typical baffles that purportedly makes it more resistant to wear.

However, it is not the quietest suppressor out there, though I suspect nothing will be that quiet on an 8.3” 5.56. Nonetheless, I like mine a lot since the AR I have it on still acts more or less the same without requiring a lot of tuning. No harsh cycling or gas to the face. I haven’t gotten around to trying it in full auto yet.

Slowmo that sounds great indeed. The 53 has the unique type spindles near the barrel tip, and the odd ish /HK 15x1 RH threads - my big concern in making the whole suppressor system work well altogether... then it has the locking piece issue as well, likely be a #3 that is bit slower vs. a #15. It's a PITA because back in the mid '70s the 53 seems not to have been "designed" as a suppressor full auto real shorty (8.3") SBR friendly platform... say Vs. It's 9mm "purpose" built little brother the HK MP5 / HK MP5 SD. Recken to hear also anyone that made all this work well together, as non common as a suppressed 53 is? The "secret sauce" if you will, seen the two HK sites online but nothing yet especially with the more recent cool Huxwrx possibilities! Thanks again Slowmo for your insights!
