Based on the HK SL7, which is a roller locked system like the G3 90 series, the 770 sports a sporting syle stock, and integral flash hider/muzzle brake. It uses the same magazines the SL7 uses. I came about this one in the early 90s when a buddy that owned a pawn store took it in. He said it wasn't worth much because the top cover had been drilled and tapped for a Leupold base (they are supposed to use a real nifty quick detach that goes for $500 bucks these days)
He gave it to me.....
It's heavy, a bugger to clean up, and typical of the HK roller guns, get's real dirty. It has an outstanding trigger, is foolproof reliable with anything that will fit in the chamber, and shoots Hirtberger 150gr Spires into a half dollar at 100m. Mag capacity is 10 rounds, or a flush fit 3 round. With the little 4x Burris it flat wears out pigs and coyotes, and will do it on the run. I took the Burris off a 22mag just to proof the rifle, and I never took it off. Kinda fits the Euro look anyway. The base is a standard Leupy Marlin 336 base with an extra hole in it. Rock solid and cheap.
If you ever get a chance to play with one, check it out. They are big milled monsters, but tame the 308 down to a mild push.
I've got your rifle's longer brother sitting in the safe right now; HK 940, .30-06. Pretty much the same general characteristics and traits. Drilled and tapped, although with mine it was to take a Weaver base. Guess a lot of folks that bought these rifles didn't want to spend the money for the HK lever lock mount setup.
Way cool, thanks for sharing. I got REAL lucky in that after I aquired it I was able to get mags here and there for practically nothing so I have 5 ten round mags. I saw on GB that the silly mags are $150-200 each...
I'm thinking about getting some picatinny "blank" stock and fabing my own rail on top. Fortunately the top covers are well built, well fit, milled, and thick and will take a tap like a bolt action rifle. Actually a rail and a nice set of rings would be the hot set up.
I've had the SL-7 forever. It's amazing how well these rifles work with good triggers. The gun deserves good ammo for how it shoots. I hate what the gun does to the brass. Those two things combined; the gun just doesn't get used like it should. Maybe it's time to set aside some brass for her.
Beautiful rifles, guys, and with the price of a nice older one today they've really got value. I remember when they came out you couldn't give them away in this part of the world but time has proven them to be fantastic machines.
Fantastic rifle.I have had mine 3 years and taken 3 white tails with it. Very accurate and with Nosler Ballistic tip ammo all were very rapid 1 shot kills. Mine came with the factory quick release scope mount that really does hold it's zero. The rifle is a pain to take down and clean and tosses the empty cases about 25-40 feet. It is a sharp looker, I love the
That's the Hk fling! I've considered buying an Hk05 mount, but I figured the mount I have is rock solid, I never take the scope off anyway, and for $400-500 I can buy a lot of other senseless stuff...LOL
Let me give you a hint on the clean operation and service. Shoot it as dry as possible, using a dab o grease in the right spots, DRY lube in the trigger pack. After shooting vacuum the receiver through the ejection port and wipe down the interior best you can with a cotton mini rag and some hemostats. Contrary to popular belief, you only have to break em down evry 500-1000 rounds. Hk's are like diesel engines, just because the oil looks dirty, doesn't mean its bad. They are dirty delayed blowback rifles and look like a smallblock Chevy with an oil leak if you over lube them.
I was looking at the ol gal the other night and poped a braincell with an idea. Lop the bbl to 16.25" and install an Hk 91 flash hider and refinish the whole thing in a satin black Teflon. That would certainly make it more portable. When you're truck shooting varmints and piggys, it's like tring to get a flagpole out the window now.
Mine will shoot a minute and a half all day long, I don't reckon lopping the bbl would make much difference. Heak, it may stiffen it up and make it shoot even better. Thoughts? Poly rifling need the length?
