A few more pictures:



This rifle has the sporting open sights mounted on the barrel, so the front sight doesn't interfere with the scope. It's an early 3 digit serial number --05XX.

 

You lucky dog ! I have been searching for a nice 270 for years most of the ones I found have been screwed around with, sights missing , pitted blue finish from neglect, threaded barrels ,stupid stuff like that or the stocks were beat all to hell and not refinishable. They are a very accurate little rifle and that beautiful factory satin blue is marvelous.
I have been in collusion with Southern Cross (Vaughan) in the land down under and I ordered a new buffer for one of my old HK 300’s . It was nearly a month in transit but no big deal…The buffer fit perfect, I just test fired it last week and shot 50 rounds without a hiccup. Take that stock strip it and then rub it down with boiled linseed oil about five or six coats and let it dry good it will be a beautiful stock …if it’s dinged really bad you can steam it and sand it, it will come out just fine (it actually looks pretty good )
Congrats those little rifles are very hard to find and are extremely expensive when you do find them.

They certainly come with a price tag. This might be what you've been looking for. Good luck! 🍀

The bluing on this rifle is at least 99% from what I can see and there's no corrosion anywhere. The stock is scratched and dinged but I'm not the type to refinish wood--if it shoots well then I plan to leave it and just use it at the range.

I'm glad to hear that you've had a good experience with Vaughn as well. He tells me that during the development of this buffer he tested it to 500 rounds with no appreciable wear to the buffer, so I'll keep a round count on this rifle and inspect the buffer every few 100 rounds or so.

Even though I got this rifle at a pretty good price its going to cost me more down the line--I'm keeping my eye out for a 300 now, lol!

 

Great ! Sounds like you got a nice one the pictures look very good. The one you have with the traditional rifle sights and not the diopter type are a little more rare and a bit earlier hence your low serial number.
Vaughan is a standup guy he will treat you right, hope he can get his buffer business off and rolling they fit perfect in the buffer housing ….never could get a response from crit-r-call but others have had luck with them. If you think that 270 is going to cost you money wait till you find a nice 300= $$$.I can’t believe how expensive they've become..

 

That stock is not bad. Rub It out with a re-finisher. Fromsby as I recall. Then with 7 to nine coats with Casey stock re-finisher. Rub it in with your fingers. You'll a nice finish.

 

Yeah thanks!!! I’ve seen that one… They do come with a price tag but those people are smoking crack. I missed the boat here recently one sold for 1150 and it was pretty nice shape….

 

Congrats on a great find! I dig the 1980s HK sporting rifles. I’ve got an HK300 myself but would love a 270 like yours. Well done

 

Well, here's what happened today--fired about 40 rounds, mostly standard velocity stuff then this happened:




In nearly 50 years of pulling a trigger something like this has never happened before.

Accuracy from this rifle was OK, but no better than my 10/22s and of course after the rear sight fell off I had a little more difficulty concentrating on shooting groups.

All told I fired about 100 rounds with 2 failures to feed the second round--there is some fore and aft play of the magazine in the well and I think the long magazine may have bumped something on the bench. I think it was seated properly, since the first round fed and fired properly. Right now fiddling with the magazine is the least of my concerns.

I think I'll just clean off the barrel and oil it up, I'm using the scope and not the irons so it's not that big a deal as far as shooting it--as for Teutonic quality, well the pictures tell the tale, don't they?

Later tonight or tomorrow, when I get around to disassembling it I'll check out how Vaughn's buffer held up and report back.

 

WOW. That is crazy. What a shame… looks like maybe it was spot welded or rather epoxied on and cleaning solvent over the years corroded it and caused it to fail. Not actually sure how they were attached originally . I’ve only ever seen a couple of the HK 270s with the rifle sights like the 300. All the others have the diopter type. , just a guess, Hard to say…😖never seen or heard of such .

 

Well, i took the rifle apart and sprayed some kroil on the spot, waited a few then hit it with the Big 45 stainless steel wool ball--turns out what looked like epoxy was actually silver solder (or silver braze). When the light returns tomorrow I'll take a picture of it--it's all nice and shiny now, lol.

You can see that there wasn't quite 100% "coverage," if that's the term, of the silver solder to the surface of the sight base so I guess over the years gun oil must have crept in and compromised the joint. Either that or the bluing salts must have gotten in the gap and corroded the joint. The bummer part is, of course as we all know, if I were to send this rifle back to H&K they would just confiscate it and I'd be out a scarce collectible (although not in it's present condition). For now, I'm just going to leave it alone and shoot the rifle some more.

BTW, if you've never taken one of these apart it's surprising how many little parts just fall out of the stock/action--there's at least one one loose pillar, a hard plastic "spacer" located between the round action and flat bedding surface of the stock and a plate or two that falls out after you've removed the screws--it's kinda Mickey Mouse in some ways but if you give it a little thought it's not hard to put it all back together. I guess on the assembly line it was a faster, cheaper way to build the rifle.

I think the magazine well is the only action part that's actually pinned in place. Half way through disassembly I thought I should take some pictures but I've lost any natural light here.

The replacement buffer showed no sign of wear, in fact the only thing I noticed was that a crumb of the original buffer got flattened by the bolt against the new buffer--no problem there, I just scraped it off. I think Vaugh's buffers are A-OK!

 

I just noticed that one of my original pictures shows the orientation of the rear sight--that'll be handy if I ever decide to re-attach the sight.

 

Well it really sucks that that happened. A good gunsmith could reattach it fairly easy. Probably wouldn’t even need to re-blue. Yes they are an intricate little bugger when you take them apart you have to pay attention to the orientation of the internal parts.

Vaughan will be glad to hear the news about the buffer. I am waiting on a couple of three pin HK 300 buffers to arrive to test for him. The material he uses for the buffers is spot on. I spent a couple of hours cleaning all of the crumbled up little bits of degraded buffer out of an HK 300 a couple weeks ago. The old brown jelly looking material had dried out ,cracked and completely crumbled. Disassembled and Blew out with a can of compressed air. It was a real mess.(see pic)
Even with all your troubles with that little rifle , enjoy it they are a rare bird.

 

Yup, those sights are silver solder on the barrels. So are the muzzle breaks on the HK 630 and 770's. Some the 630 and 770's have a fine line of rust where the muzzle breaks meet the barrels.

 

Yeah silver solder ,especially older silver solder jobs are susceptible to corrosion like that… that’s the first time I’ve ever seen a sight base detach from one of the HK sporting rifles. Looks like it was a weak solder job and years of corrosion finally got to it.😖

 

Congrats on the HK270, would love to add one to my collection some day.

The model you have is sought after because it does not have the 90 series rotary rear and front site towers so adding a scope is more natural.

Get that rear barrel site reworked and enjoy it!!

Terrific rifle you scored, there!
Mine gets a work out at our club's annual VetFest fundraiser on the rimfire line. People love the lines and it's accuracy, as well as it not being (yet another) 10/22.
It's a longshot, but do you have any way of measuring the hardness of the buffer?
I made a single-shot mold and found that the same material for ear-plugs works great. I bought a durometer, as well as the sample pack from McMaster-Carr, but I have no reference to compare to.
Maybe this:

I would say that earplug material is way too soft. The buffers I have tested for VAUGHAN who is making them is much more robust rubber than what an earplug would be. This is his email maybe contact him and talk to him he’s a great guy.

* I caution again I would not use any material as soft as what an earplug is made out of for a buffer in this rifle.*

 

No, I don't have a way of testing the hardness of the buffer. I can say that it has held up well for the 300-400 rounds I have put through it so far. Now that I found a couple more magazines this rifle will get more range time.
