    Navy NSWC Crane M83

    Besides the M83 there were a few other SOF rifles with McMillan (Anschutz-style) Prone and Baker Special stocks. Delta plank-holder Sergeant Major (retired) Norm Crawford shot for years with McMillan Baker Special stocks at work, Camp Perry, and as a member of the United States Palma Team. I...

    Navy NSWC Crane M83

    SOCOM hits and misses like anyone else's procurement system. Mother Army would have NEVER bought a bigger than 300 Win Mag system if it wasn't for USASOC. It's always better to have Mother Army buy gadgets and modify / hot-rod them for commando purposes. Limited funds go farther when someone...

    Suppressors Mk12 suppressor history - OPS Inc, Allen Engineering, etc.

    My Special Forces company had a number of "Crazy Phil's" OPS INC cans for our CAR-15s. Once Mike Haugen retired from the Army and became the Remington Military Division Rep (and later VP), there's a reason M24A2 was fitted with OPS suppressors. They were simply the best available (capability...

    Why would a scope be made with MOA turrets and Mil-Dot reticle

    Hey, Fokker! I resemble that! :ROFLMAO: Simple Redfield ranging hairs. Bracket an 18-inch space (shoulders to solar plexus, nuts to nipples, or nipples to top of noggin), shoot it, kill it. Other variations:

    Why would a scope be made with MOA turrets and Mil-Dot reticle

    The M21 sniper rifle's Leatherwood Automatic Ranging Telescope hashes subtended 30 inches -- roughly (but not quite) nuts to top of noggin of a GI E-type silhouette. An E-type is closer to 1 Meter, but when I went to sniper school we only shot to 600 yards with the M21. It was close enough.

    Why would a scope be made with MOA turrets and Mil-Dot reticle

    I meant to be a little sarcastic. I am an American. There are two types of nations on this Earth -- those that use Metric, and those that have walked on the moon.

    Reloading Perfecta brass?

    I took this picture of the shitty flash holes in Perfecta 5.56mm brass. I can't imagine they do anything for precision or consistency. There are two generic Federal cases there for comparison. Someone else's photo:

    Why would a scope be made with MOA turrets and Mil-Dot reticle

    Military binoculars had mil reticles for ground and anti-aircraft artillery adjustment (as well as range determination) in WWII (if not earlier). Marines adapted the mil-dot reticle for rifle shooting in the Unertl sniper scope. American military riflemen shot on Known Distance rifle ranges...

    MK 12 Picture & Discussion Thread

    24.5 of TAC for both 69s and 77s. 23.4 of 8208 for 77s. 24 Varget for 77s, 24.5 for 69s. Don't sacrifice precision for velocity.

    Die Leaving Scratches In Brass - Once Fired

    Once you've cleaned and polished the die bore to your satisfaction you can keep up with and maintain it by periodic polishing with something like Mother's or Meguiar's mag wheel polish.

    Navy NSWC Crane M83

    Not so much parochialism as capacity and availability. All Marine Corps M40s were custom-built by Precision Weapons Battalion 2112 Armorers and gunsmiths. Their schedules and capacity were full keeping up with internal demand. Starting in 1985, Army met their requirements by buying the...

    MP5

    I have a three-digit MP5 SBR conversion originally sold as an HK94 as well. It has the original HK94 stamping on the receiver. The Form 4 and NFA Registry says it is an MP5 SBR. Simple Green and water make a good-fair solvent -- just be sure to rinse it off thoroughly and lube. As stated...

    New (to me) Remington 40X

    If it's engraved "U.S." it's a surplused Army rifle (vice "USMC"). Yours looks like mine from around 2010 -- medium taper barrel and the Remington 700 back-swept bolt handle (as opposed to the straight 721-722 handle). It should shoot really straight and tight with almost any ammo. I paid the...

    Precision AR -15 10 shot moa groups

    Take off the bipod and shoot off of bags. The longer lock time of an AR hammer trigger compared to a striker-fired bolt action is enough to throw off new precision AR shooters. Couple that with a wobbly bipod and you're giving away stability.

    MK 12 Picture & Discussion Thread

    For DMRs and SPRs we don't shoot 80s for slow-fire. The majority of the ammo through DMRs will be M855A1. Through SPRs mostly 77s. Really depends on the customer and training audience. I think my last personal SPR barrels have been Satern Liberty, Roscoe, and White Oak. Wannabe SPR. Needs...

    USAMU used/made both during my time there (a while ago). Depends on what blanks were in the supply room. Proof is in the performance. Every single USAMU build gets tested -- there's no wondering whether or not the build was right.

    Ops inc adapter/ extension

    What is your finished barrel diameter behind the threads? Otter Creek Labs makes a one-piece thread-on mount that may do what you want (possibly the one Allegheny offered above).
