Thoughts on a new one?

If I was you, I'd probably get a new one.
Repairing the old one might be more trouble than it's worth.

But seriously, I've never seen a flash hider self destruct.

I'd get a slotted one instead of duckbill/prong unless duckbill/prong looks is important.

I was joking about repairing it. Yeah this thing is going on the wall of “Well that didn’t work”

When I got the barreled receiver, this was on it and on it tight. I wonder if it wasn’t over tightened causing it to have stess against it. Then 60-80 rounds doing mag dumps heated it up enough to make it let go. I figured it came loose and feel off or got hit by a round as it unthreaded itself. Didn’t expect to find it split in two....one piece was 6 ft to the right and the other 4 ft to the left. The pieces literally went 90 degree to the gun. It was crazy where we found them.

 

Consider Smith Enterprises Vortex Flash Suppressor as replacement. Your presentation is the force generated by the HK51 is causing the split - unless the bullet is tumbling. Likewise these were used on HK53 and lack the barrier when the bullet exits the barrel. Another reason why blast deflectors are used - both to divert force and generate force for the firearm to cycle.

SAMMY!

 

I'll check those out for sure!! No marks on the pieces to indicate the bullets were tumbling. I kinda figure the heat and blast pressure is what did it in.

 

7.62x51mm NATO in a pistol length barrel has to be crazy loud.

A slotted flash hider will have a ring supporting the end and should be a more resistant to splitting the way your prong flash hider did.

Cool "cutaway model" flash hider you have there.

 

One is none and two is one.

 

Lets just say its a little rude...but it is a lot of fun. The gun is just about as worthless as a three dollar bill, but I like it overall. Let a young man shoot it the day before and the look on his face said it all....

 

That's the face I love to see when I take friends shooting with me. Well done sir.

 

Back in the day I had a Volmer HK-51B with flash enhancer than made a great fireball and felt like getting slapped in the face (lovingly of course) with every round fired. Does anyone know who made them or if they’re still being made?

 

I was at a shoot over the weekend and the 4 prong flash hider on my HK51 decided it didn’t want to be on my HK51 anymore.....think I need a new one. The threads on the barrel are fine, thing just split down the middle....literally! Granted I shot the living hell out of that gun, doing a duel with my neighbor who had a 7.5” M16. I ran 3-20’s in the same time frame he ran 2-30’s.

Barrel threads and muzzle are fine, the thing just gave out.

Thoughts on a new one?

Happened on my 51B and 53. They really bark and flash w/o one.

 

Yeah them fireballs are massive.....I'd like to get my hands on a 51B for a 50 round belt just so I could go full retard.......an HK21 is nuts.....an HK51 is stupid......an HK51B....sure why not!! LOL
