    Scope field evaluations on rokslide

    DoD. Even so....most companies do not submit their products to DoD. DoD puts out contract notices and companies submit their products for testing and evaluation. Generally, it is always the same companies submitting products because most optic companies products cannot meet the rigorous...

    Scope field evaluations on rokslide

    Going back 22 years... There was good reason why S&B and to a lesser extent, NF, were the predominate scope selections for SOCOM and USMC Force Recon units down range. I would not call it abuse, but these scopes/weapons systems were very reliable all-the-while subject to very, very hard use...

    6.5 PRC Powder Charge/Velocity Ladder Test. No Flat Spot

    Having been at the reloading bench 50+ years now...the biggest advancement we have at our disposal is technology and reams of data it produces. And therein lies, the rabbit hole (and the rabbit hole has ALWAYS been there!). To crunch the data, we use statistical models. And regardless of the...

    Ignored members quoting you?!

    I don’t ignore anyone bc even a blind squirrel finds an acorn now and then. That acorn can be a nugget of wisdom I’ve been missing.

    Help- my gun won’t group

    I thought that as well! I wasn't sure if he was shooting from that setup or set it up just for images. There will be a lot of movement in that table as the bullet travels down the barrel if that is your shooting platform. But I agree, use a rock solid benchrest is a must. If one is not...

    Help- my gun won’t group

    A lot of good suggestions have been mentioned above and worthy of investigation. A thought from looking at your images.... Are you absolutely sure your Pic rail is properly torqued to the action and Loctite 242 applied to screws? The Marine Corps generally uses a HD ring/base up front, the 6...

    What barrel contour for chassis

    Since you aren't going to tote or run with it...go with the straight taper. And I love my MPA chassis. If you plan on competing, be sure to dig into the rule book for the International Benchrest Shooters. While you don't need a "special" rifle to compete, it is best to know the rules before...

    + length gas systems

    When it comes to direct impingement rifles (AR10/15) getting the dwell time correct is critical to reliable performance. Dwell time is the variable based on the distance from the gas port to the muzzle end of the barrel, not including any vented muzzle brakes or flash hiders. Not a distance...

    Beware!!! SRS knock-offs floating around

    And I will add... I envision it would be very difficult to obtain a patent for a muzzle brake by simply applying for a patent. Muzzle brakes are common place components and readily available in the public domain. I suspect to obtain a patent on a muzzle brake design, one would have to go...

    Beware!!! SRS knock-offs floating around

    My thoughts exactly. While I try hard to buy from reputable vendors who own the intellectual property of the products they produce or from vendors who license the intellectual property. But often times it is hard to do. If one were to design and build the most outstanding widget ever...

    Barrel porting vs. muzzle break vs. suppressor ?

    Naked muzzle brakes are just no fun, especially for anyone nearby.
