Nice, thanks! Any ideas for a good optic mount and optic combo? My roommate just got one of the Nikon M223 that looks pretty cool. What magnification level would be overkill?

Out of the M223's, none of them are really overkill but the 2-8 should suit your needs.

Oh definitely. I mean they worked well enough for the Soviets! But I can't tell if those are "reconditioned", new lenses only, or what.

Merry Christmas!

I love those type of scopes but I've found that they can be kind of hit or miss. I've had one where it just cracked right down the center of the mount for no discernible reason. (bad cast I imagine) They may also have trouble staying tightly mounted, though that can be fixed. That said, they're really nice for the cost and I just bought another one despite the issues I've had with them.

I've heard that the rifling inside the ak74 barrel tends to overspin the bullet to increase the yaw of the projectile upon impact. However, this seems like it would be deleterious to accuracy. The guy that works at the guns and ammo store in my area first described this to me and recommended that you load heavier bullets if you want to shoot more accurately. Granted he said his experience was on an Egyptian Mahdi. Any thoughts on this?

Yeah over-stabilization is only a worry if you're shooting a bullet that is far too short (light) for your twist rate and at very long ranges.

Most of an AKs problem with accuracy is ammo related rather than mechanical.

3 shot groups are worthless esp when its not a bolt gun. Show me 5 10 shot groups, take and average, and then we can talk accuracy.

Accuracy is not the problem with a short barrel, velocity is. 6.5 G is not the short barreled performer that 6.8 SPC is. Might as well stick with 7.62x39 which is actually almost as good as 6.8. The only prolem with x39 at that point is limited bullet selection, there are only about 1 or 2 decent choices.

so IMO, pretty stupid.

Well, at longer ranges, the lower BC of bullets for 7.62x39 are gonna kill its performance. This is why there's a reason for a 6.5 Grendel AK to exist: http://imgur.com/rfebi

Neo Mara posted:

And if you're concerned about a long ranges, why on earth would you make a short barreled AK the gun to start with? Keep in mind velocity figures for 6.5g are usually out of 20"-24" barrels. What's your velocity like after 12" of barrel? Its not ideal at even at short range, let alone the long ranges where the high BC of 6.5 starts to become a large factor. Keep in mind the bullet needs to do more than put holes in paper. If putting holes in paper is your only goal then again the 6.5G short barreled AK is stupid.

Show me a 20"-24" barreled AK in 6.5G with real groups and not this 3 round bullshit and then we can talk about a niche gun.

Ah, I meant a 6.5 AK as a concept, not necessarily a short-barreled one. I just think a 6.5 AK would be an amazing general purpose rifle.

I'm sort of a fundamentalist in that way. I don't really see a reason for the existence of other top rails than the TWS since that is, in my mind, the best one. I don't really consider an AK to be a fun dress-up gun like an AR-15 since in my mind it is the best tool for the job so I don't own it for looks.

What job is that, exactly? Engagements under 200m ?

I was thinking 300m, but yeah pretty much.

I more or less agree with Mishaco here, but I think an elegant solution for mounting optics on the AK can be found in a TWS style dust cover rail. That is the lowest rail I am aware of and it holds zero excellently. Also rather than add weight to your rifle by sticking a huge rail over the top of your cover it actually decreases it because it is an aluminum part that replaces your original dust cover. It also increases your sight radius when you use the peep sight included with the rail.

22 Eargesplitten posted:

Okay. Did TWS used to make one that wasn't the dust cover? I thought I remembered that name being associated with that problem.

Yes the Gen 1 was an over the top rail and I think it did have some problems with that.

Maybe with adjustable sights. I would not feel incredibly comfortable engaging targets (you know- the kind that shoot back) past 200m with a stock AKM.

Agreed. I think the main limitation of the platform is the sighting system. There's no reason a quality AK can't be made to shoot out to 500 yards with a proper scope and a stable rest. Though that is about as far as I'd be comfortable trusting the 7.62x39 round out to. I have seen articles about AK's chambered in 6.5 Grendel doing MOA at 800 yards and have no problem believing it.

The AKM platform excels up to 200m, beyond that, even with the PSOP (4x24 or 6x42), you're effective to 300-350m. It wasn't designed to engage further. The M16A4 (AR-15 with 20" or 18"SPR) frequently engages from 300-600m. AK's are fantastic. The round they fire is fantastic. They are a great carbine platform, but stretching them out further than that will yield mixed results.

If you were comparing them to a standard 16" profile AR-15 or a M4, I would understand the logic of your statement.

I think that when talking about a 7.62x39 AK in standard military configuration you're absolutely right. And same goes for an M16A4. However either of those rifles can stretch a little further when configured to. Just an example a quick search turns up of a 7.62x39 AK being used out to distance: http://www.themodernsurvivalist.com/?p=1324.

And that really is about as far as I'd expect that caliber to be usable with that setup. A 6.5 Grendel AK, firing a vastly more efficient cartridge should do well out to distance. Here's an example of such a gun by Marc Krebs: http://www.youtu.be/watch?v=GhAcUNj...eature=related. That is an early version of the gun that there was a Shotgun News article written about. My recollection of it was that it was just over 1 MOA at 800 yards. Some quick googling tells me that it was all hits on an 11.5" plate at 800, so probably more like a 10" group. Slightly over MOA. 6.5 Grendel at that distance has only about 20% less energy than a .308 Winchester at that distance, and nearly 100% more energy than a .223 Remington. That's a cartridge that can make any gun seem impressive.

commissargribb posted:

Who shoots an AK from a rest besides a really cheap fudd?

Unless you're talking about a hasty supported position.

Well I don't necessarily mean a lead sled or something, but the point is to show the mechanical accuracy of the gun itself. Saying a 7.62x39 AKM off hand will be less accurate than an M4A1 off of the bench says a lot more for shooting supported than the weapons themselves. It's more about getting an apples to apples comparison.

This makes sense from an academic standpoint I guess but I still think a comparison made this way denies the context of the weapon as a combat tool.

It absolutely does, however you can't say definitively that a weapon is inaccurate if it is being fired off of the shoulder. In that case I am much more likely to blame the shooter than the weapon. You simply cannot say the AK is an inaccurate weapon because you intend to use it in a way that doesn't allow its mechanical accuracy to show. The accuracy you're referring to otherwise is an accuracy based more in ergonomics, sighting system, and the individual shooter's skill.

This is not really what I meant to say. What I meant was that given all aspects of the rifle (in stock configuration) and the way it is normally used* (not the way I intend or an otherwise controlled environment) the effective point target engagement would seem limited to 200m.

*standing kneeling and prone unsupported or standing or prone supported from sandbags or over the hood of a '93 honda civic and sometimes burst fired from the back of a Nissan pickup truck.

Moreover, if you change the caliber, add optics fire it from a rest or a "lead sled" or otherwise remove the human aspects of shooting, you can greatly increase the accuracy of the rifle.

Well again you're sort of giving a personality to a weapon in saying it is meant to be used in ways that don't allow accurate shooting. I would never claim an AK fired over one's head from the bed of a speeding Toyota in fully automatic would allow 2 MOA shots at 450 yards, but I would certainly claim that an AK fired from the prone with a modern western scope mounted on a TWS style rail from a portable sandbag rest could quite easily hit man-sized targets at 500. Many firearms are capable of this, but it seems odd to me to say that a weapon that certainly can shouldn't because you think it wasn't meant to. (edit:) Though I can kind of see where you're coming from saying that a stock AK-47 fresh off of the lines in 1949 in the hands of a Soviet conscript isn't capable of such feats, I don't think anyone here is going to say a modern M16A4 with a six power ACOG scope shouldn't be fired further than 400 yards because the M16A1 is difficult to use from standing at 300.

There is a reasonable expectation that the subject will be dropping prone, or kneeling behind cover to accomplish these shots. Personally, I find that carrying a shooting bench wherever you go makes these shots much easier.

Exactly, it's not like anyone would say a rifle can make repeated 500 yard shots from standing, because that's not something I'm aware of humans being able to do.

edit:

commissargribb posted:

The techniques I have in mind are outlined a translated soviet manual on operating and firing the AKM. If you like, I can try to find it and post some scans to show you where it never mentions firing from a rest.

So really what you're arguing is not that the AK is incapable of such shots, but that there's a book that doesn't explicitly recommend it. I don't see how that has much to do with my point of what the AK can do.

this is what I said when I mentioned that fire is accomplished from hasty supported positions. Hell, it gives me a little trouble hitting a 350m target with ANYTHING nevermind something with terrible sights.

What I'm arguing is not that it's INCAPABLE on a mechanical level. I'm just saying that shooting from a rest against a stationary target in the clear with a scope vs shooting prone over sandbags are two different things.

So what you're really arguing against is supposed effective ranges using different levels of support in a shooting position. In that case I restate my position and agree that it is easier to fire off a bench than unsupported standing. I personally can hit a torso-sized target at 250 yards 5 for 5 unsupported with a 10 power scope, but add a sling and take away the scope and that range may change. I don't really see what this argument has to do with the AK in particular though.

The original statement was that the generally accepted effective point target engagement range with an AKM was 200m. Implicit with this is that it is a combat weapon and being used from combat fire positions. You said something to the effect of "I can fight the Afgan War from a rest and hit Mujahedin from 500m away". So yeah, the AKM in particular in a combat situation is good to about 200m.

I think that when talking about a 7.62x39 AK in standard military configuration you're absolutely right.

What you are saying is that rifles cannot be used past 200 yards in combat situations because of a lack of good shooting positions, not that the AK I describe cannot as it is more than mechanically accurate enough. Someone should let the dudes in Afghanistan running ACOG's on M4's know to stop trying to shoot past 400 yards because you can't get a good enough position to do so. And also, in my opinion, safeties are relied on far too much. In fact if there was ever a time that you benefited from your own use of a safety, you are probably too dangerously incompetent to be around firearms.

The TWS rail replaces the dustcover, and its overall height is about the same as the dustcover. If you already have a magnified optic that mounts on a standard rail, hold it on top of the dustcover to get a half-rear end representation of where it'd be mounted on a TWS rail. The Beryl rail is slightly higher.

The TWS rail is seriously better than the Beryl, as it's actually lighter than the original dust cover, instead of just adding more weight, not to mention how much lower it is. At the SHOT show I got to check out Parabellum Armament's half-assed clone of the TWS Gen 1 rail and even with the higher rail height on that one I could see through a ~24mm objective lens optic with perfect cheek weld on an underfolding stock.

Quick and dirty calculation on Hornady's website says it should be about here: http://www.hornady.com/cgi-bin/ball...utton=Calculate So still potentially deadly at 1000 yards so long as you've got a scope with 100 MOA of elevation travel plus some holdover.

More work for most people's stomachs. I dremeled about 3mm of aluminum from the inside of the top rail to accomidate the gas block and I'm fashioning a more reliable solution to keep the gas tube in place since you have to position it completely differently compared to how it's design. You also have to reduce the diameter of the bolt carrier by about 1-2 millimeters to get it to fit into the tiny gas tube.

Mind you none of this ruins the rail from being used on a regular AK, but a lot can go wrong.

Yeah, that'd be a little scary with a Dremel for me, personally. I may give it a try on the mill once I get a Draco. Sounds like a great setup, though. I really like the Draco as a carbine since 7.62x39mm does very well in a short barrel like that.

Can you bake Alumahyde?

It doesn't require a baking time at all. It just air cures over the course of a week or so.

Here's what Brownells has for instructions on it: "Warm the part and the Aluma-Hyde II to about 90F. Spend a couple of minutes shaking the daylights out of the Aluma-Hyde II and apply a medium coat for good coverage. You can recoat in a few minutes but don�t wait more than thirty minutes. Once Aluma-Hyde II starts curing, you must wait until it�s fully cured to recoat. You can cut the cure time to approximately two days by circulating warm air (90F works fine) past the part. Absolutely no primer coat is required for a tough, durable, abrasion-resistant, rustproof finish that blends beautifully and compliments all gun finishing applications."

I think I'll do a couple of coats of Alumahyde matte black and see how it turns out.

How much time did you allow for coats to dry? Also how the heck do you get paint from sticking on your cookie sheet when you are baking it? Also did you bake after letting it dry for awhile? And did you let it really set in for a few days after baking?

You've got to let Alumahyde sit a week before you can apply another coat unless you recoat within 30 minutes. Also don't bake it since I don't think that's an "approved," method for curing it. If I recall correctly it just gets really glossy and melty looking if you do. Krylon is a totally different story though.

Maybe I'll just do Rustoleum only. Kinda sucks trying to finish stuff in San Francisco weather though. Foggy early morning til 10 or so, and even then its still 60F or something.

Just be aware that Rustoleum probably won't hold up to solvents well.

Alright I've got some pictures of my Alumahyde'd AK up now if you're interested:

I have also thought of building an SLR-106CR clone. I am going to have to look into this further, because I would have to perm attach the muzzle device to skirt the SBR zone. Not sure if I like that or not. It would also require that I chop up a nice new virgin .223 barrel and take a hit on velocity/precision due to the shorter barrel.

.223 is kind of a bad caliber to be reducing barrel length on as intermediate calibers go. However you're not losing any mechanical precision/accuracy in doing so if that's what you mean. I wouldn't worry about it too much though, especially since you can just run some heavier loads to mitigate that a bit. Also that underfolder is the sexiest looking underfolding AK I've ever seen.
