H&K 91, Slow-Mo Jerry Miculek Style

Just when one thought Jerry was content with setting records with a .50 cal BMG and shooting double barrel 1911s as fast as his inhuman finger could, Jerry goes to town on a 1980’s H&K 91. 20 7.62×51 rounds go downrange faster than many full-autos.

On top of his normal shooting capabilities, Jerry goes into a bit of history on how he came about the rifle (hint: he won it and many like it) but also some insight on speed of the operating mechanism of the rifle.

    That’s no mean feat…of all of my 308 BRs, including FALs, AR10s and M1As, the HK91/CETME/PTR91 recoils the most. Big old chunk of metal whacking back and forth in there.

      I wonder what would happen if he stepped back further than 10 feet? Kind of pointless at that range, eh?

      • Zebra Dun

        I’m thinking Jerry would nail it.

      Ever tried it with a reduced charge load? Say a 150 grain at 2,500 fps?

  • Giolli Joker

    I thought the charging handle was fully reciprocating during fire, the fact that JM still has a left thumb seems to prove me wrong.

    • SP mclaughlin

      Nope, the charging handle should be static with the roller delayed blowback action. Hence why the charging handle is manually locked back first to execute an HK slap.

      • Giolli Joker

        Cool, thanks.

    • Jonathan Ferguson

      The handle is attached to a cocking tube inside the upper receiver. This assembly is not attached to the bolt carrier group; a bit like an AR charging handle flipped 180deg. If it were possible to lock the bolt to the rear on the roller guns, the cocking handle/tube would slide freely like the AR equivalent does if not correctly latched forward.

    I didn’t know that about the fluted chamber helping to lubricate the case during ejection to reduce the chance of stripping the rim. Very cool

    • John Shore

      Well, sorta. A fluted chamber doesn’t really ‘lubricate’ the case, but instead allows the gas room to flow into the flutes around the case to ‘float’ the case on a cushion of gas and prevent it from sticking. The flutes are why HKs are so dag blag dirty after firing; The flutes allow some gas to flow past the cartridge case and partially interfere with full obturation.

    Is Jerry on the Army pick a pistol board?
