THE FOLKS IN GRANT'S PASS, OREGON, HAVE BEEN UP TO SOMETHING .... AGAIN. FROM THE NOVESKE RIFLEWORKS WEBSITE: "Noveske Rifleworks is proud to announce the Switchblock; an adjustable gas block for use on rifles with sound suppressors. Patent Pending."  THOSE FOLKS WHO SHOOT SUPPRESSED MUCH OF THE TIME WITH THE D.I. GAS SYSTEM WILL WELCOME THIS ADVANCE. I EXPECT TO HAVE A NOVESKE 16" MID-LENGTH BARREL WITH THE SWITCHBLOCK INSTALLED TOMORROW. LOOK FOR PIX OF THE COMPLETED BUILD SHORTLY AFTER. GOOD SHOOTING, WES GRANT MSTN.BIZ |
Ahh. it will have an off setting. Beautimus! I'll be waiting with a credit card handy

OK- THE BARREL IS HERE AND THE UPPER IS ASSEMBLED. I LIKE THE SWITCHBLOCK! HELD TOGETHER BY BUT ONE ROLL PIN, THIS DEVICE IS PRECISE AND POSITIVE. IT HAS THREE SETTINGS: THE NINE O'CLOCK POSITION IS WHAT WE'LL CALL "NORMAL", FOR UNSUPRESSED USE. THE POSITION IS NOT MARKED ON THIS EXAMPLE. THE TWELVE O'CLOCK POSITION IS "OFF", SO DESIGNATED BY AN "O". THE THREE O'CLOCK POSITION IS FOR FIRING SUPPRESSED, APPROPRIATELY MARKED WITH AN "S". IF CHEN LEE'S NOT TOO TIRED AFTER CRUISING THE SHOT SHOW THIS EVENING, MAYBE HE CAN HOST THESE PIX I'VE SENT HIM. GOOD SHOOTING, WES |
THE SWITCHBLOCK WILL NOT FIT UNDER THE 12" RIFLE LENGTH URX FOREND. YOU'D NEED TO SWITCH TO A MID-LENGTH FOREND FOR YOUR PARTICULAR APPLICATION. BE FOREWARNED THAT REMOVING A PROPERLY INSTALLED URX FOREND IS NOT A FUN ACTIVITY. I'LL HAVE PIX UP SOON OF A 16" RIG WITH MID-LENGTH GAS SYSTEM. IT LOOKS VERY GOOD, IF I DO SAY SO MYSELF. THE VLTOR VIS UPPER COULD EASILY BE MODIFIED TO ACCOMODATE THE SWITCHBLOCK WITH A FOREND LONGER THAN THE GAS SYSTEM, E.G., CABINE LENGTH GAS SYSTEM WITH MID-LENGTH VIS-2/2A, OR MID-LENGTH GAS SYSTEM WITH RIFLE LENGTH VIS-3. MY THINKING IS THAT THE SWITCHBLOCK WILL BE A NATURAL CHOICE ON SUPPRESSED 18" AND 20" BARRELS WITH FULL LENGTH GAS SYSTEMS AND 12" FORENDS. I PLAN TO ASK JOHN NOVESKE TO COME UP WITH WHAT HE FEELS WOULD BE AN OPTIMUM PROFILE UNDER THE HANDGUARD FOR A "NEW" STIFFER 18" SPR BARREL DESTINED FOR USE WITH A SUPPRESSOR. WE CAN CALL IT OUR "SPR MK 12 MOD 2" BARREL. GOOD SHOOTING, WES |
THAT IS THE EXPRESS PURPOSE OF THE SWITCHBLOCK.
WE EXPECT NEWS FROM NOVESKE RIFLEWORKS ON THIS SOMETIME AFTER THE SHOT SHOW. WE DON'T EVEN KNOW THE COST YET. GOOD SHOOTING, WES |

THE VLTOR VIS UPPER COULD EASILY BE MODIFIED TO ACCOMODATE THE SWITCHBLOCK WITH A FOREND LONGER THAN THE GAS SYSTEM, E.G., CABINE LENGTH GAS SYSTEM WITH MID-LENGTH VIS-2/2A, OR MID-LENGTH GAS SYSTEM WITH RIFLE LENGTH VIS-3. would this involve cutting out some top or side reails, or just a couple of the flying buttresses in between? thanks Wes!!! |
I'M JUST SPECULATING, OF COURSE. I DON'T PLAN TO MAKE SPARKS FLY ANY TIME SOON. USING THE MID-LENGTH GAS SYSTEM AND VIS-3 AS AN EXAMPLE ....... I CAN SEE HOGGING OUT FIVE RAIL SLOTS AND ASSOCIATED SUPPORTS ON TOP OF THE VIS-3, SLOTS 38 - 42. THAT WOULD ALLOW YOU TO DROP THE BARREL INTO THE VIS-3, ALIGNED WITH THE AXIS OF THE RECEIVER, WITH THE SWITCHBLOCK OCCUPYING THE FORWARD PORTION OF THE HOLE YOU JUST MADE. THEN, YOU'D HAVE ROOM TO SLIDE THE BARREL EXTENSION INTO POSITION, LEAVING THE SWITCHBLOCK ENDING UP WHERE SLOTS 38, 39, AND HALF OF 40 USED TO BE. THIS WOULD LEAVE ABOUT AN INCH OF BARREL EXPOSED FORWARD OF THE SWITCHBLOCK, AT THE ADDRESS 40.5 - 42, BUT I SEE THIS AS NO BIG DEAL. IT WOULD STILL LEAVE SLOTS 43 - 45 FOR YOUR FOLDING FRONT SIGHT. OF COURSE, SINCE THIS MIGHT COMPROMISE THE VIS-3 TO A DEGREE YET TO BE DETERMINED, VLTOR MAY SEE THIS DIFFERENTLY! RIGHT NOW, THE OBVIOUS THING TO DO IS USE A FOREND THAT WILL ACCOMODATE THE GAS SYSTEM BEING USED. GOOD SHOOTING, WES |

THE PURPOSE OF THE NOVESKE SWITCHBLOCK IS TO PROVIDE THE SAME AMOUNT OF GAS TO THE OPERATING SYSTEM WHEN SHOOTING SUPPRESSED, WITH THE SWITCHBLOCK IN THE "S" OR SUPPRESSED SETTING, AS THE WEAPON PRODUCES UNSUPPRESSED, WITH THE SWITCHBLOCK IN THE NORMAL SETTING. ONE RELATIVELY ACCURATE YET SIMPLE WAY TO MEASURE THIS IS TO COMPARE THE WEAPON'S CYCLIC RATE IN EACH POSSIBLE CONFIGURATION. UNSUPPRESSED, WITH SWITCHBLOCK IN THE NORMAL SETTING - 697 RD/MIN SUPPRESSED, WITH THE SWITCHBLOCK IN THE "S" OR SUPPRESSED SETTING - 711 RD/MIN PRETTY DARNED CLOSE !!! I'D CONSIDER THE SWITCHBLOCK A SUCCESSFUL DESIGN. GET THIS: SUPPRESSED, WITH THE SWITCHBLOCK IN THE NORMAL SETTING - 875 RD/MIN !!! THAT'S 23% FASTER THAN IN THE "S" OR SUPPRESSED SETTING. GOOD SHOOTING, WES GRANT MSTN.BIZ |
| I don't have any experience with suppressors, so did I get this right? The suppressor holds back all the gas from escaping the barrel, causing more to travel through the gas system, and this product will cut that excess gas down to unsuppressed levels? Very cool. |
A suppressor holds back some of the gas, not all. Yes running a smaller gas port would compensate for the increase in back pressure caused by a suppressor. This gadget reduces the size of the gas opening in the "S" mode. |

I sent off an email to Noveske about the Switchblock, in regards to the use on my Noveske SPR 18" unit with my M$/SPR can. Wondering if it could be adapted to it. This is the answer I got. While not really a problem since the M4/SPR can by AAC does seem to be less prone to gas blow back issues. It seems (I could be wrong) that for now the Switchblock is desiged for 10.5" and 16.1" barrels. Since the Noveske 18"SPR is special and uses a mid-length gas system (under the VIS handguard) that it won't work for my use at the time being. Great concept. I like the idea, maybe I'll just get another Noveske upper & can hahaha "It's currently only available for the 10.5 and 16.1" Barrel lengths. It's designed for specific lengths. Hopefully in the future we'll have more. Best Regards, Sheri Office Manager Noveske Rifleworks LLC" |
