HK 770

btmj · May 28, 2013, 12:26 AM

A local gun store has an HK 770, early 1980s. For those not familiar, this is a hunting gun made from an HK G3 action mounted in a monte carlo walnut stock. It is a good looking rifle, in a funky odd way.

It is chambered in 308, comes with a 3 round and 10 round mag. Stock is in great shape. The LGS wants $700.

Does anyone know if this rifle will take standard G3 mags?

Where there any issues / problems with these guns? Given the reputation of HK, my expectation would be that this is a very fine rifle.... true?

It is not a G3 action.

It uses the roller delayed blowback, like other HK long guns of the time, but the 770 uses a milled steel receiver instead of the stamped like the G3.

I had a HK SL6 for several years, which is a .223 cousin to the 770.

The 630 and 770 had those Monte Carlos stocks.

The SL6 and SL7 had a bit longer stocks, with a vented handguard over the barrel.

None of these accepted military HK magazines. HK military magazines have a catch area much like an AR's: left-rear of the magazine and generally large and rectangular.

SL7/770 magazines came in 2 capacities: 3rd and 10rd.

The SL6/7 and 630/770's magazines have a catch area at the rear of the magazine that is not much more than a horizontal slot. If you look closely at the trigger guard, you can see the magazine release lever at the front.

Excellent information, thanks.

It's a real shame these don't accept HK-91 or G3 mags.
