    Rim Lock With 3" shells

    I recently purchased 5 of the 8-round Saiga-12 magazines. So far they have worked flawlessly with 2-3/4" shells as long as the action cycles far enough to eject the fired case. But a couple of them have a problem with 3" shells. The nose of the top round gets pushed down by the feeder foot on the bolt as the bolt is coming back, which causes the rim of the top shell to snap behind the rim of the next shell down. When the bolt comes forward, the top shell in the mag cannot push forward because its rim is caught on the rim of the shell below, and the only way to clear the stoppage is to remove the magazine, and press down on the second shell in the magazine while simultaneously lifting the nose of the top shell to disengage the rims. Is there a fix for this, or do I have defective mags? Top shell in normal orientation: Top shell rim locked:

    Suppressing a Draco

    I've standardized on .300BLK. I's a lot easier to get it to run reliably in an AR platform, wally world and other big-box stores are carrying it now, it works great in short-barreled guns with minimal energy loss, and fired from a 16" barrel, the supersonics aren't much louder than a.22LR--you can fire supersonics unsuppressed without making your ears ring, although I wouldn't call doing so "hearing safe". You almost don't even need a can. It's highly effective on deer, pigs, and thugs out to 200+ yards from a SBR, pistol, or rifle. And suppressed it can be as stupid quiet as a .22 with subsonics.

    Suppressing a Draco

    It's far easier to find subsonic .300 Blackout than subsonic 7.62x39.

    And a lot of them grow up to be keyboard commandos.
  7. Hard to reach area, not surprising it got missed.

    My completed Saiga 12

    Sights make a huge difference if you ever shoot slugs. And they make it much easier to actually center a shot pattern on the target.

  10. You're not very bright, asking that question on a gun board. How about the guy who owns a firearm with a barrel 0.1" shorter than some arbitrary number, who gets sentenced to a lengthy term in prison even though he never used it to commit a crime or acted irresponsibly with it. Who is the "victim" if someone merely owns a firearm that fails to meet certain arbitrarily-defined unconstitutional criteria?

    9 mm ar build

    The 80% polymer lowers I've been using (EP Armory) are thicker in that area than a milspec forged aluminum lower, except for 12:00 where the charging handle has to clear. Were the failures you reference pistol builds with naked buffer tubes, or were they SBR/rifle builds with shoulder stocks? I would think shouldering a stock would transfer some of the impact shock from the buffer tube threads to the shoulder of the shooter.

    9 mm ar build

    Around the hammer pin, or somewhere else?

    9 mm ar build

    I disagree. Polymer handles shock better than aluminum. Aluminum will dent and crack under an impact that will only deform polymer momentarily, then spring back to its original shape. Also, if there is concern about the hammer pin holes opening, KNS pins offer additional support and wear prevention, especially if you loctite the hammer pin to the receiver and pin supports.
  14. Evolution IS a religious debate--an attempt to use misuse science to explain past events that cannot be observed by present-day humans. For example, evolution offers no coherent or plausible explanation for the origin of life. If you read the literature, there are endless theories on how life began, but they change constantly as we gain greater understanding of how life actually works. Until someone can synthesize a colony of viable living organisms from inorganic materials in a lab, even a simple bacteria, it's all speculation and fairy tales, not actual science. Real science is observable and reproducible, and no theory of spontaneous origin of life has ever been corroborated with observations, or reproduced in a lab. Believing that life started spontaneously requires a greater leap of faith than that demanded by any religion. If you look at the number of DNA base pairs needed to build even the simplest of organisms, the odds of evolution producing one single viable organism (something capable of living, finding food and shelter, and reproducing) anywhere in the universe since the Big Bang is about 1 in 10^100, even if you stipulate that the universe is 13.8 billion years old, and every atom in the universe can sequence a billion sets of DNA base pairs per second, and no two atoms ever generate the same DNA sequence. Of course, that glosses over the difficulty that any device or organism that can generate DNA sequences is necessarily composed of billions or trillions of atoms, and generates sequences at a much slower rate than 1 billion sequences per second. Bacteria generally have a generational interval of 5-15 minutes, for humans and other more complex organisms,the generational interval is a minimum of 12-14 years, but generally more like 20. Also, most of the atoms in the universe are parts of stars or floating in deep space, where extreme temperatures, radiation levels, or other hostile conditions would irreversibly damage or destroy DNA before it could be placed in a compatible host cell and start reproducing. There's also the difficulty of the compatible host cell--it is even more unlikely to form by chance than the actual DNA, and the DNA and the compatible host cell have to be spontaneously assembled in both physical and temporal proximity in order to create a viable organism capable of sustaining itself and reproducing, all in an environment that doesn't destroy it immediately. One can debate the scope and nature of a higher power or supreme being(s), but the notion that life happened by chance or accident is preposterously unscientific.
  15. I have an AR-10 and a G3, so I'd keep the shotgun. But YMMV.

    Rim Lock With 3" shells

    I received the replacement followers today, and they seem to address all of the issues I had with 3" shells. I loaded all 5 of my mags with 3" shells and hand-cycled all of them with no rim lock, low feeds or any other issues. Looks good so far. Kudos for great customer service!

    Re-read post #31.

    Csspecs 10 rd saiga-12 magazines are ready.

    Look at the thread about rim lock with 3" shells in the csspecs forum.

    magazines ?

    Because of the tolerance variations in Saigas, custom fitting magazines to the gun is pretty much mandatory. Discarding a brand-new mag because it doesn't fit perfectly out of the box is totally idiotic on your part.

    magazines ?

    All mags have to be fitted to the gun, due to loose tolerances. Getting rid of a mag because it requires fitting is just stupid.
  21. The A-10 is designed for close air support--flying low and relatively slow over a target and shredding it with its cannon. The F-35 is designed for supersonic air combat. One is a chisel, the other is a screwdriver, and using either to do the job of the other is flagrantly idiotic.
  22. G3 surplus wood furniture is available online, for fairly reasonable prices. I have a spare set laying around I'm not using.

  24. I have a PTR-91, and it's a nice gun, but has a few quirks. The roller blowback action is unique, and makes shooting the thing more comfortable than most 308s, at least if you have a good buffer in the stock. The desigh is pretty hard on brass; the chamber flutes make funky ridges in the neck and shoulder of the case, and ejections usually makes a nice dent in the side. So I usually shoot Tula steel case, which it eats like a fat kid eats Skittles, and is about the same price as brass 5.56. CTD has it for a little under 40 cents a round shipped. The ergonomics aren't as well thought out as an AR. The safety requires you to take your hand off the grip unless you have huge hands, and pulling the charging handle is not for girly men even if you get the extended charging handle (which I highly recommend). The magazine release button location is similar to that of the AR, but further forward relative to the grip so you have to let go to activate it. The blowback action also means that the gas impingement design of the AR is clean by comparison--the thing gets FILTHY after not many rounds. But that doesn't stop it from going bang every time you pull the trigger anyway. I've got over 200 rounds through mine so far and even though I haven't cleaned it at all since the clean and lube I did when I first got it, it still feeds and functions just fine. The groups have opened up a bit from fouling--they went from ~2" to about 4". It's an interesting gun, but not for everyone. I'd recommend shooting one before you decide to buy one.
