HK 51

LGS here in Switzerland is selling this gun from his personal collection. I’ll apply for a special permit (since it’s full auto) and buy it in a few weeks. I didn’t know this model so made some internet research and found gun Jesus’ description and videos

« The HK51 is not a gun that was ever actually produced by Heckler & Koch. It is instead a variation on the G3/HK91 originally developed by American H&K specialist Bill Fleming. He was contracted by a UK-based company called FR Ordnance to produce a submachine gun sized version of the G3 for British SAS and SBS use. Both agencies did actually buy a few examples, and used them a few times operationally. Some testing was done on specialty ammunition for them, but they were ultimately replaced by the rather more practical HK53 (essentially the same gun but in 5.56mm).

Where the HK51 saw most of its sales was on the US recreational market, with both Fleming and others making the guns, often in combination with registered H&K auto sears. With full-power 7.62mm NATO ammunition and all of an 8.3 inch barrel, the HK51 serves best as an attention-getter on a range full of other machine guns… »

It’s obviously based on a Portuguese made G3 from March 1963 (FMP - Fabrica Militar de Portugal)

Anyone here knows more about these ?

In any case it’ll go well with my MP5

Nice gun! That looks very much like a HK-93 A3 that I sold about 5 years ago. My 93 was semi auto and was .556/.223 caliber. Of course I wish that I still had it but I needed the money at the time.

I remember seeing ads for the Fleming "HK 51" and the tagline read,
"Report of a .50 caliber, recoil of a .223"...

never understood how that could be actually true, but it made good ad copy..

The US full auto (select fire is included) market is complicated and expensive and out of my reach, though not my interest.

I'm sure it would be most impressive at night!

From what I've read about these, they chew up brass. Don't expect to reload any of it once it's been fired. Still would love to have one myself.

It took a bit longer than anticipated, as I ended up buying four FA rifles and arranged all the paperwork / permits and funds in one go (others were the already shown HK 33, M2 carbine and M14 rifle).

But its finally home



It came with three mags, the 20 rds being as old as the gun

















Barrel is marked IB_X



Can’t wait to try it out
