IF AND WHEN WE GET THE OPS INC MILITARY BRAKES AGAIN, IT IS THE DESIRE OF THE OPS INC BOSS, MR PHIL SEBERGER, THAT THEY NOT (!!!) BE SOLD SEPARATELY, BUT ONLY WITH OUR PROPERLY CONTOURED SPR BARRELS OR ON OUR COMPLETED SPR UPPERS, JUST AS WE HAVE DONE IN THE PAST. SO THAT WILL BE THE ONLY WAY TO GET THEM.

FOREST IS CORRECT. BLACK HILLS AMMO TYPICALLY USES POWDER WITH FLASH RETARDENT. IT'S GOOD STUFF.

THE OPS INC BRAKE IS NOT DESIGNED TO HIDE FLASH. BUT IT DOES, TO A DEGREE. IT IS A PATENTED MUZZLE BRAKE THAT ENHANCES THE ACCURACY OF THE WEAPON AND, WITH THE BARREL COLLAR, PROVIDES THE INTERFACE BETWEEN THE WEAPON AND THE ULTIMATE FLASH SUPPRESSOR, THE OPS INC 12TH MODEL CAN.

Q3131A IS NOT SUITABLE FOR THIS PARTICULAR BARREL/CHAMBER COMBINATION.

THE CHAMBER IN THIS PARTICULAR "REAL" SPR BARREL (MADE OF UNOBTANIUM) IS THE ONE SPECIFIED BY CRANE, AN A.M.U. MATCH CHAMBER. MATCH CHAMBERS ARE EXTREMELY TIGHT, MINIMUM TOLERANCE UNITS DESIGNED TO BE USED WITH MATCH AMMO HELD TO SIMILAR TOLERANCES. Q3131 HAS HISTORICALLY PROVEN TO BE ONLY A NOTCH ABOVE WOLF/NORINCO IMPORTED AMMO. THAT IT DOES NOT CHAMBER DOES NOT SURPRISE ME TOO VERY MUCH, NOR SHOULD IT CONCERN YOU.

WHAT WOULD BE GAINED FROM LEARNING HOW MEDIOCRE (AT BEST) 55 GR AMMO SHOOTS IN A PRECISION WEAPON WITH A 1X7" (NOT 1X8") TWIST DESIGNED FOR HEAVIER BULLETS? PLEASE FORGIVE ME, BUT THIS REMINDS ME OF THE ANALOGY OF MIXING EXCREMENT WITH ICE CREAM. IT DOESN'T DO MUCH FOR THE PALATABILITY OF THE EXCREMENT, BUT IT REALLY MESSES UP THE ICE CREAM.

I HOPE YOU'RE USING A GOOD BORE GUIDE WITH THAT BARREL. DO YOU NOT MIND THE RESULTS OF AN OPEN LEAD BASE BULLET BEING FIRED IN SUCH A BARREL?

THAT PARTICULAR UPPER CAME THROUGH M.S.T.N. I KNOW FOR A FACT WHAT IT IS CAPABLE OF DOING WITH FEDERAL PREMIUM MATCH AMMO. SORRY, BUT I FIND IT DIFFICULT TO "CUT THE CORD" SOMETIMES.

ACTUALLY, WE DID NOT BUILD THIS PARTICULAR UPPER, BUT WE HAVE BUILT SEVERAL JUST LIKE IT. IT IS THE "REAL THING", WITH A BARNETT-BUILT DOUGLAS BARREL. THIS PARTICULAR UPPER WAS THE BEST SHOOTER OF THE DOZEN BUILT, TOO.

I TYPICALLY SHOOT:

FEDERAL CMP MATCH 69 GR
FEDERAL CMP MATCH 77 GR
BLACK HILLS 75 GR - RECENT ADDITION

SINCE THEY NO LONGER SELL THE 77 GR FEDERAL LOAD THROUGH THE CMP, I TRY TO RATION IT CAREFULLY. MOST SHOOTING IS DONE WITH THE 69 GR FEDERAL LOAD. IT WORKS WELL IN EVERYTHING IT SEEMS. BUT OCCASIONALLY, A BARREL, LIKE THE LMT MRP, SHOWS A PREFERENCE FOR THE 77 GR LOAD. ONE SPR SHOT BEST WITH THE BH 75 GR AMMO, TOO.

HALF THE FUN IS FINDING THE BEST COMBINATION.

BUT I ONLY SHOOT MATCH AMMO IN SPR UPPERS.
