    Gunsmithing Blueprints/specs for turning barrel blanks into AR barrels?

    Ive done a bunch of bolt gun barrels but never AR barrels. I need to machine a 20" AR barrel and a 8.5" AR pistol barrel. Anybody know where I can get the specs for the locations of the gas ports, etc? Thanks. Edit: I actually just need to know the gas port location for pistol length and...

    Rifle Scopes Where to get scope diopter for focusing closer?

    Waaaaaayy back on the old Hide there was an optometrist among us that made & sold diopters to go on the end of rifle scopes so the scope could focus/parallax @ closer range. These still around?

    Independence day & no regard for frozen feet

    Independence Day and no regard for frozen feet. ““The second day of July, 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated as the day of...

    Advanced Marksmanship Just want to check myself.

    And here we have it. Why I eventually stopped coming around Snipers Hide years ago. But I was still selfless in that I left my stickied articles in place in the various sections for the few decent people.

    Hyper Stabilized Bullets - Jim Boatright

    Ive been out of the loop for a little while but Ive never heard of a gain barrel gaining more than 2-3" of twist. May I ask who makes such a barrel? That's exciting.

    (previously posted this in the Stupid Question section with no takers. The flying VLD.... While likely nutation will occur once again when the bullet goes transonic...I got a (claimed) physicist demanding there's never the cessation of precession. However everything I understand says...

    Maggie’s Thinking about the passing of Gunny Ermey....

    Been doing a lot of thinking about the passing of Gunny R. Lee Ermey and other Marines today. (I need to stop thinking....) But the funniest thing I ever heard from a DI was "I can make out the coat hanger marks on your forehead you low life, no good...

    Gunsmithing Can't find a long enough boring bar for a good price. Or deep hole, small diameter boring. ?

    Nice, but I think a plunge (sinker) EDM is more handy for gun work.

    I have been thinking along those lines. Or a piloted counterbore....and machining an extra long pilot.... Thanks.

    300wm sizing ?

    Technically yes, but its still in the web area of the case where it's very thick. Also .015" is only the thickness of a poker playing card. Hardly any. Ive done it to every LR belted mag Ive owned with never a problem. And I load hot..... I have heard lots of people doing this mod. No...

    300wm sizing ?

    Best thing you can do is have a smith chuck the barrel in the lathe and move the relief in the chamber for the belt forward about .015" with a boring bar. This negates the belt and lets her headspace off the shoulder like she ought too. Good accuracy gains follow.

    Just wanna double check myself.

    If your interested, google: obturation nutation gyroscopic precession yaw of repose aerodynamic jump (the vertical drift that always occurs with horizontal drift) & Magnus effect and it's component of Eotvos effect.
