After WWII the Army incorporated induction dampening into the M1938 design. Induction dampening is a beautifully simple concept. It takes advantage of the inductive magnetic field generated between a swinging compass needle and a highly conductive but non-magnetic alloy like copper. When a magnetic needle (or bar) is placed inside a cup made of copper and the needle swings (oscillates) that movement causes a slight magnetic eddy current to form. When the needle swings to the left the eddy current pulls it to the right. When it swings to the right the eddy current pulls it to the left. The eddy current is self-canceling; as the needle oscillations decrease the eddy current strength decreases and very quickly the needle settles down and is aligned with magnetic north. Simple, elegant and effective.

However, by the late 1940s the Army decided it was time for a whole new design. The Army took the best functional elements of the M1938 compass – the lensatic sighting design and the combined degree and mil scales on the compass card – added induction dampening, a needle lift device, a much larger sighting lens and a larger thumb loop and placed it all in a beefed-up waterproof aluminum housing. The resulting compass was designated the M1950 Lensatic Compass. It is a rugged, versatile device that has remained in use with the US military for over 60 years, pretty much as originally designed.

- M1950 Lensatic Compass This particular compass was manufactured in February1953 by the Marine Compass Company out of Pembroke, Massachusetts. The cloudy dial cover is the result of the plastic aging. Remember, this compass is almost 60 years old!

The same compass with the cover closed. At the time of this writing Cammenga has been the sole supplier of lensatic compasses to the US military for over 10 years.

Sometime in early 1942 a photographer asked General Patton to strike a pose doing something dramatic. I don’t know who’s idea it was to have him pull out his compass and shoot an azimuth to a distant point, but the resulting photo is interesting. Patton is standing beside his early M3 Stuart command tank and decked out in full battle regalia – tanker helmet and goggles, tanker jacket, binoculars, signature pistol at his side and an M1938 compass in his hands.

Looks like I'm not the only one with those concerns.

I do have to admit that the DR, on a purely performance-based evaluation, does seem like a great optic. When I think about using variable magnification optics like 1-4s or 1-6 or 1-8s or even that 1-10x by March Optics, how often would you dial between the minimum and maximum?

I mean sure if you're lazily plinking away you might dial something specific but within the hundred-whatever yards it'll be on 1x, and past that I'm pretty sure 99% of the time, the user will just rip that sucker to max so they can get a bead on quick. The Elcan at that point seems most logical, as it removes pretty much what you'd never use in the first place for a "fighting" optic. Makes me wonder if they make some sort of condom you could stretch over the Elcan to keep shmoo out so it doesn't go all sidewards if you get sand in the moving bits.

Either way I go back to >>102005. You could even streamline it further with a micro (pistol) red-dot and a fixed power scope.

tl;dr I hope to see optics come out in the future that are like an Aimpoint H1 that had sex with a Specter DR or a 1-8x S&B Short dot or something. Something bomb proof, killer battery life, throw-lever from 1x to whatever x.

>>102116
I've got a SpecterDR 1.5-6x on my SCAR 17. I'm reasonably pleased with it, but that price is a pain in the balls for sure. My biggest gripe is that, while the thing seems pretty sturdy, for that kind of money I expect ELCAN to have a warranty like Vortex does -- it doesn't matter how it gets fucked up, a replacement gets sent. From what I can tell the warranty is pretty much bog standard.

Practically speaking, with the 1.5x I'm pretty happy to use it as a scan optic, and the 6x works good for precision. I'm pretty pleased with the reticle, and the illumination functions work well, though the full-on crosshair illumination is a little funky in that it doesn't actually illuminate the entire thing like one might expect. Not really a problem though, just odd.

Despite the fact that it's got a dot, picking up up fast will take a lot of practice and muscle memory. I wouldn't feel good snap shooting with one, but it does have basic irons on top and you can always add a red dot. I perched a little Vortex Venom up there, but haven't had a chance to play with it much since. One thing to note about the irons is that they're pretty low, so the front flip-up lens cover pretty damn near obscures it if you go that route. You can thin it out with a Dremel and have it workable, but frankly I expect better on a piece of kit this pricey.

In terms of logic, it looks like you're kinda on the same page I am. Fuck it, it's either lowest or max power, the middle range is almost never used. May as well make the transition fast and easy.

Long story short: It's a good optic, I like it. Is it $2500 good? Ehhhhhh... at that point you really need to play with one, IMO. Personal preference is what's going to decide that. Unfortunately, they can be a pain in the dick to find. Would I buy mine again? In the same circumstances, yeah, I probably would. It was a treat for myself and funded entirely by overtime cash worked explicitly for that purpose. I'd be a hell of a lot happier at a better price point or with a better warranty though.

I have the strike eagle 1-6x

Pros: Awesome reticle, red dot feature is good and easy to use, eye relief/picture is better than scopes anywhere near that price range (But not still GREAT, just good), mine came with free caps too which is a plus, and obviously the price is great

Cons: Heavy, the dial to turn magnification is rough/small/slow to turn, eye relief changes as you change magnification is dramatic enough to require you to change your head position (But this is also true of other 1-4 or 1-6 scopes in this range)

IMO it's the best BUDGET 1-6x optic. It leaves a lot of "quality of life" features to be desired, but it knocks all the standards out of the park. I've had experience with a VX2, a burris, and a few other 1-4 or 1-6x scopes and I found this to be the best. Grab it on sale for $230 or so, and you can't go wrong

>Jerry Michulek(sp?) swears by the strike eagle and uses it in competitions, he keeps it dialed up at 6x and uses a vortex red dot at a 45 degree angle for the 1x shots

>>102186
> Grab it on sale for $230 or so, and you can't go wrong

Interesting. I'd like to see if the next generation of v-mag scopes will come down in price thanks to Vortex.

>>101986
I always assumed Mexican 1911s would be mostly .38 Super.

>>102145
They are.

Then why say it's already the standard in Mexico?
.380ACP (or .380 Auto) is not .38 Super

Actually yeah, if it's scaled down it'd be kind of neat to mess with and what's the harm in another gun anyway?

I like the standard size 1911, a mini one would be adorable.

That and I have an inexplicable love for thumbhole stocks. I blame Dragunovs

For some reason Stag Arms got the exclusive for Hera's CQR stock, I guess they make more CA legal rifle?

I wonder if they are going to sell the foront grip too.

>>102161
According to their FB page, they are putting them up for sale soon

>>102143
i really hope that with the release of the p10s that p09 and p07 mags become cheaper. i'd hate for the p10 to become the vp9 2.0 where the "selling point" was that you could use p30 mags with the vp9.

then again, happy merchants gonna happy merchant, i guess.

Why have you been saging all of your posts, recently?

>>102153
It's to be polite, but mainly because the post is going on a thread on the front page, so it doesn't really need bumping.

>>102154
There is a thread on the front page of this board that was most recently bumped twelve days ago. You're breaking my method of reading through until I find the first thread that hasn't been modified since the last time I checked.

>>102155
Never really thought about it like that. I just hold down scroll wheel and zoom down the page to look for a new post (it's an at-a-glance thing, the size of the thread on the page changes or something, hard to explain how it "looks" when it's zooming past), I've missed a few things when doing it your way.

Gonna try hard and not sageru. Hard to resist.

Thanks bro.

>>102120
How do you like it? I watched the whole series when it was first posted. Ian and Karl seemed really proud of building it, but luke warm with the rifle itself.

>>102133
I mean, it's a roller-delayed 5.56mm. In theory it's not really doing anything different than an HK33/HK93, neither of which were ever massively popular. It's a unique piece with some retro cool factor, yeah, but it's not gonna compare particularly well to say, an AR15.

>>102043
I assume it was extraction/ejection. It looks like the round went off, extracted, but didn't leave the rifle.

I tried an SU-16 and it cycled like it hated life. Not sure why the case didn't fly out as I would expect, but with a rifle that cycles as violently as the one I tried (assuming mine was a regular example, I don't know, haven't shot other examples), if the case doesn't go a mile out and slips off the extractor early, the bolt coming back and closing on the empty case at just the right angle could crush the case like that.

Just speculating, OP should return and tell us more about it.

General weird malfunction thread until then, I guess?

>>102060
I shot my buddies and am buying one myself-sounds like the one you handled was fucked.

The only thing I found remarkable about it was the shitty sights, rifle functioned fine.

>>102064
The one I tried did "function". It had no malfunctions or stoppages or anything, but it functioned very enthusiastically.

Like "maximum over-rape" enthusiasm, but it did work.

>>102069
So, did it function like it hated life, or just like it was loving life a little too much?

>>102144
It kinda felt like the gun was like "PARTY HARD YEAH" in that "I don't expect to live that long since I'm made of cheap parts, but I'll do my best until I spontaneously disassemble" kinda way.

So I'd expect it to work with no issues in any situation with any ammo until all the guts shit out from any available orifice.

Do you have a micrometer? I'm curious about the compromises PSA made in the dimensions of their 7.62x39 bolt. 7.62x39 has a larger case head than 5.56x45, which supposedly is why CMMG went with a larger bolt and bolt carrier group in their Mutant.

>>102097
I don't have a Micrometer, only the caliper there are plenty of 7.62x39 shooting AR-15 uppers, I think CMMG went with AR-10 because of the mag well change since they are on AR-10 base why not mod the bolt to work with 7.62x39

Here is someone's picture of the KS-47 bolt next to CMMG Mutant's bolt

Start handloading.

>long answer
I'm sure the Rem 81 is a fairly strong action, but the cartridges were loaded usually under 40k CUP. Few modern rounds are that mild, but I don't think it would blow up the rifle to chamber it in another similar rifle caliber. Since it's a long recoil, I severely doubt 10mm Auto would cycle it; more than that, the action is meant for rifle rounds and getting it to feed pistol ammo would be another headache. The 30 Rem is similar to a 7.62x39 in muzzle energy, but the case is bigger and lower pressure and the bore is 308 instead of 311, yet I would likely start there if you do want to convert it somehow. It'll be pretty damn expensive either way to have a barrel made or the original rechambered or bored out and sleeved or whatever you end up trying. It'll be honestly a shitton more than a press, dies, and brass.

Also, cutting a rifle round barely halfway up the case body and "parent cartridge" is a bit of a adventure time jake-rubber-band-for-miles stretch when you're going for something that can cycle and feed in a rifle...

The easy answer is to reload. Get one in .35 Remington so you have an excuse to get a Marlin 336 and reload for them both.

>>102074
I actually just got myself a marlin in .35 rem for christmas. Going to reload it with my cast 158gr flat noses I use in .38spl/.357mag.
Classy as shit and hard thumping.
Got it after IV8888 did their brush gun video and I saw it used my favorite imr 4320 powder.

>.30 remington, the parent cartridge of 10mm

And also the parent cartridge for 6.8 SPC, if you wanted an off-the-shelf caliber that'd be actually really handy in a little takedown gun like that.

Afaik the takedown assembly/barrel extension is probably pressed/pinned. Not certain, but if push came to shove a good machinist should be able to salvage that part and assemble it to a new barrel. I've seen K31s rebarelled by reusing the chamber end, anything's possible.

>>102078
You. I like you. I don't reload yet, but doing that is a long term goal of mine once I do. I have a soft spot for Marlin 336s, but don't/can't hunt with a rifle in my state, so a .30-30 or .35 Remington is dumb. A .35 Remington loaded to .357 Mag levels would be a great, affordable plinker.

And I could get a Model 8/81 and try to make it run with reduced power loads.
