  1. The technical drawings call for the carrier and fasteners to be sealed with Permatex #3 Aviation Form-A-Gasket. As far as I know, that's still part of the milspec requirement. It takes time though because the gasket takes something like an hour to cure, so manufacturers don't like doing it, so they skip it. Everyone is obsessed with "properly staked gas keys" which only takes about 30 seconds, so they use that as a marketing gimmick because it's what the internet has decided is important. Truth be told, many people in the industry would like to get rid of staking altogether, but their customers demand it so they really don't have a choice. An unstaked carrier is almost unthinkable. Honestly, it would be enough to sink a company if word got out that they didn't stake their carriers, so they're not about to even suggest the idea in public. Young's can afford to do what they want because they make mostly OEM (you likely have at least one of their carriers and don't even know it). The end manufacturer then does the staking themselves. The reason Young's refuses to stake is because they know it means that they get more carriers back for warranty work. If you stake one of their carriers, you void the warranty and they WILL charge you to replace it if it ever comes loose. It's true that most "milspec" BCGs on the market aren't fully milspec. The only one I know for certain that is, or at least was, is Colt. But I don't know if that applies to their civilian products, especially those made before they merged their civilian and government assembly lines. According to Colt, the new LE6920s have the exact same parts from the exact same line as the rifles they send to government agencies, obviously with the exception of the fire control group. So if that's the case, then any Colt M16 carrier theoretically should have the permatex gasket. One thing to be aware of is that you see companies refer specifically to the bolt as milspec, so that's one way to kind of scam people into thinking the entire BCG is milspec. If you start questioning them about the carrier, extractor, etc. you usually get a lot of hem hawing around. 99% of people automatically assume that just because the bolt body itself is milspec that everything else is good to go. Sorry, I don't know about LMT. Just because you can't see it doesn't mean it's not there. I have a Young's carrier that also shows no sign of it, but I know it's there.
  2. And I would love to give you an honest answer, but apparently I've been silenced.
  3. There are lots of professionals in the industry who don't like staking them, I suppose they're retarded too? The truth of the matter is that most manufacturers do it because people think it's gospel to do so. You say the military specs demand it; well they also demand a permatex gasket, and NO ONE does that anymore because it takes time and it can't be used as a marketing gimmick (i.e. "properly staked gas key"). If you look at any "properly staked" gas key that's come loose, the stakes are still fully in place, meaning the screw didn't rotate at all, meaning the staking didn't do shat. According to Young's the staking actually makes the key more likely to come loose because it stretches the top threads, which basically creates a time bomb as the threads settle from top to bottom. But hey what do they know, they've only manufactured a few million or so BCGs in the last 30 years, and they only do all the OEM for retarded people like Les Baer, Wilson Combat, Ruger, etc. And they're only the most respected carrier manufacturer in the industry. I believe Wilson called them the "finest manufacturer" and the "best AR rifle bolts we have found."
  4. I don't know the physics behind it, but the clamp on ones are much more stable. I've never heard of a clamp on type coming loose, but I'm convinced that any set screw type would eventually come loose if given long enough. I personally don't think that loctite does anything to help the situation, but it probably couldn't hurt anything. My theory is that the threads stretch over time, not that the screws back out. The reason I believe that is that even if you stake the screws the thing can still come loose, so I fail to see how loctite could help if staking doesn't seem to do anything. All I can really say with any certainty is that any serious manufacturer either uses clamp on or pinned gas blocks. If you intend to use the rifle for home defense, I would suggest going that route. If it's going to be limited to plinking, then it's a non issue. If you do get into 3 gun, you probably will want to make it bomb proof, as those matches are a big investment and they're hard on guns. It would suck to invest all that money into the match only to have your gas block give out halfway through the course. The gas system length depends on barrel length. The 3 gun people seem to prefer 18'' for whatever reason, which is the shortest barrel that can reliably cycle a rifle length gas system. There are also mid length 18'' barrels, and now there are even some in between lengths starting to show up. I think that would definitely fall into the "opinions are like assholes" category you referenced, but lots of people say the rifle length 18'' barrels can be finicky with weaker ammo. Considering plinking ammo is often weak, you might want to opt for a mid length. If you go with a 16'', all I can tell you is that my 16'' mid lengths shoot anything and everything all day long with any buffer/spring combo and they're noticeably softer shooting than my carbine lengths were.
  5. I'm a big fan of the arm wrap method if it's an option. I wouldn't say it helps with recoil so much as muzzle rise and overall stability. It's really more of a way to steady your aim, and I feel like it helps me recover more quickly.
  6. http://www.rusmilitary.com/html/firearms_svd.htm These guys might be able to help you, but they're going to have the genuine article, not the repro, and priced accordingly. I know I've seen repros, I just can't remember where. I didn't see the link to the one from Kalina, so that might be more of what I'm talking about. Also keep in mind that there were different versions of these, and there's one that I've read was popular on the PU snipers that were used long after the war ended. There are two main ones I'm aware of off the top of my head, the SVD one, and then a second one that was made specifically for AK74s equipped with grenade launchers. The shape of the AK74 stock is very similar to that of the mosins, so my best guess is that's the one you want. However, one site I saw had at least three or four different versions, so there are more I'm not even aware of. I really think your best bet would be to get on the marketplace subforum of one of the AK specific sites and see if you can find someone willing to sell you one. That's how I've found all my rare combloc stuff. There are people in Eastern Europe who have access to this stuff by the truck load who sell it on the AK forums. ETA: The one in the photo is the same one forsaken linked you to.
  7. I know this is considered blasphemy, but I never stake my gas keys. If they come that way, fine, but I much prefer them unstaked. There's a very good argument to be made that staking is either unnecessary or counterproductive, so I wouldn't worry about it too much.
  8. There are plenty of good reasons to use a clamp on gas block. It's also important to understand that dimpling alone won't prevent a set screw type from coming loose. All it does is make alignment easier, and in the event that the block does come loose it will buy you some time by preventing it from rotating and thereby sealing off the gas port, but eventually it will be loose enough that too much gas escapes and it won't be able to cycle anymore. The only way to make a set screw gas block 100% secure is to pin it. The only issue you will run into with clamp on gas blocks is that they normally don't fit under the super slim handguards you're wanting. There's one on the market that I think will fit under a KMR, but you'll want to check the dimensions to make sure. It's from SLR rifleworks, but it's pretty expensive. If you decide to go with the standard set screw block and your barrel of choice doesn't have a dimple already, BRD Engineering has a jig that works really well. Just keep in mind that it centers off of the gas port, so if your gas port is off center so will your gas block. I ran into that once with a cheaper barrel. You can also use the gas block itself as its own jig if you're very careful not to dink the threads. You basically just get the gas block aligned, clamp down the screw furthest from the gas port, then use the appropriate size drill bit to mark the dimple under the gas port. After you've started the dimple, remove the gas block and finish it. I would highly recommend not doing that unless you have a vice set up on your drill press. I would also recommend installing the barrel into the upper receiver and using the flats on the receiver to level it in the vice. ETA: My bad, that's not SLR. It's from a company called Next Intent, and I know nothing about them other than they make a really pretty gas block.
  9. When you say dimpling, do you mean for the gas block?
  10. They won't do it while Trump is in office if they know what's good for them. They might have a last hurrah during Obama's final months, though. I know one thing: if Trump wins, Obama will do everything in his power to leave behind the world's biggest pile of shat for him to clean up.
  11. My fear is that they would turn into small versions of Mexico within our own borders. Even if they didn't continue to get welfare, you know congress would give them hundreds of millions in foreign aid.
  12. There have been Caucasian remains found all over North and South America. Not only do the haplogroups prove they're from Europe, but the facial reconstruction is hard to argue with. They found one guy that looks exactly like Patrick Stewart, and he's like 10k years old according to carbon dating. The Indians are all up in arms about it because they know it's been going on for a long time. That's why they won't allow supposed "Indian graves" to be studied. Despite the fact that the people are obviously not related to any tribe in any way, they claim them as their ancestors anyway just because the graves are in areas claimed as sacred by some tribe somewhere.
  13. If you want something that's kind of sort of correct for the rifle, you could get him an SVD style buttpad for it. The Russians made SVD type buttpads for several different rifles and grenade launchers, and they have been known to use them for Mosins sometimes. Probably not the Russians themselves, but combloc countries that used surplus Mosins into the 70s or so. I can't remember which version it is, but there is one that is supposed to fit pretty well on a Mosin stock. The original ones can be very pricy and hard to find, but there are repros out there. The guys on an AK specific forum could probably direct you to one. I believe the one below is a repro.
  14. I would recommend having a spare carrier key and fasteners. I had to replace my first one a few months ago. Other than that, the only part I've had to replace was a trigger group, but I didn't keep track of how many rounds it lasted. On that particular rifle, I upgraded the BCG somewhere along the way, otherwise it probably would have needed TLC around the same time. I always seem to trade/upgrade my rifles before major things start breaking. I have the disease bad and can't stop chasing that dragon to find the better mousetrap. The only BCG part I'm aware of that will last indefinitely is the carrier body itself. One thing to think about is that many bolts will outlast a stainless barrel, so depending on your setup your bolt may actually last for the life of the build. But during that time you may need 3 extractors. Gas rings are also a must, and I hear the cam pin can go pretty much anytime, or last forever. Of course you'll want firing pins, and probably extractor and ejector springs.
