I don’t know where you live.
The dog handlers I know all use the real deal.
When a criminal case is over, the dope is destroyed once it is no longer needed.
Dog handlers will take some of that to be destroyed dope and use it for training their dogs,

I know one dog trained for firearms and explosives The conservation officers have it. Poachers often toss their guns in an attempt to avoid arrest

And a local agency has a dog trained to sniff electronics. They use it on the CP search warrants. Think of all the images you can put on a 1TB micro SD card. And all the places you could hide that card.

Would there be a lube that would mask whatever the dog is trained to smell,like fruit scented astroglide?

>>108361
Shouldn't be an issue.

>>108361
As 5.45 said, there shouldn't be an issue. Since the sights or optic are mounted to the barrel/upper receiver, that all stays in the same alignment.

>>108362
>>108363
Thank you for the response.
I assumed it would be ok. I will still head to the range and double check.

So now I have 3 uppers and 2 lowers. Other than cost savings. is there any reason to have a lower for each upper?

> So now I have 3 uppers and 2 lowers. Other than cost savings. is there any reason to have a lower for each upper?

The only need for additional lowers is to have different configs or to have more functional guns at one time. 'Case you need to arm yourself, your cat, and your dog all at the same time... or something.

Unless the cat and dog don't get along, then I'd recommend against it.

Mechanical zero is based on the sights in relation to the bore.
Since in the AR-15, both are rigidly mounted in the same component (unlike say, a FAL) a swap would not change any mechanical zero (or boresight).

However you would still need to do a final sight-in to compensate for changes in hold due to stock (or sight plane in reference to eye and bore) or distance from eye to sight line.

>Less parts, lighter weight potentially
Maybe the concept would be applicable in the recoil mechanism concept of the KRISS Vector? Might add bulk but not much weight and control recoil well?

  Correction, on the Tavor 7 the ejection can be swapped without changing any parts.

However you're still not switching shoulders on the fly.

Been looking at the keltech RFB as well, seems comparable and so much cheaper. Actually starting to look like the best choice.

>>108323
I too was drooling of the Tavor until... I held one. Felt cheap and the trigger sucked (bullpup I know but still)
>>108331
I had an RFB for a time and it was surprisingly reliable even with Brown Bear garbage ammo and alternating brass nato and wolf. It did fine. Eventually it ended up in my friend's possession and he put a suppressor on it and it broke the ?slide?operating plate? spring retainer piece? The company sent him a Gen 2 part which was beefier and that did the job. It was actually a decent gun. Good luck checking the chamber though...

Having owned a Tavor for a few years, I don't think the T7 will change my thoughts on Tavors in general.

Pros
>bullpup (this being a pro is up to you, but I do find the same OAL with less short-barrel-muzzle-blast is good along with the other commonly mentioned stuff)
>quick mag changes, shot-to-shot on timer of 2.5 seconds average after a few hours of practice, better shooters could get sub2 pretty easily
>reliable
>tough
>overall a good firearm
>can be shot both shoulders because brass deflector

Cons
>expensive
>inaccurate, especially for the price
>heavier than what they say it weighs
>rear heavy, with reciprocating mass well above the shooter's firing hand making the gun teeter-totter in recoil impulse. The shooter's firing hand becomes a bit of a pivot point where the rifle can rock muzzle up as the BCG travels rear and muzzle down as the BCG goes home (for me anyway, other shooters might not have this issue)

AR-15 impulse by comparison. This particular AR has a 14.5" barrel, FA BCG, carbine gas, and a regular birdcage. The difference is more dramatic when shooting them side by side versus watching a potatocam video.

Just learned that Bond Arms makes .45 ACP barrels. Do they genuinely make good backup pistols? A pocket holster seems like a good way to carry one. Maybe for house carry as a minimalist option. Anyone carry one?

I carry an inexpensive American Derringer Corp M-1 .45 Colt/.410x2.5" snake gun when I go on hikes in rattlesnake country or occasionally when I carry concealed. Back in the late '80s in San Jose, California, I was hiking with a friend in the hills and we came upon a large rattlesnake under a thorny bush. We could have just gone around the angry reptile, but my friend pulled out a stainless steel clone of a Remington 1865 Double Derringer Model 95 and fired at the snake. His gun was loaded with .410 shotgun cartridges filled with small birdshot. Worked like a charm! Dead rattlesnake. Remember to carry this in an open holster if you do not have a concealed carry permit.

My ADC Derringer is heavy for it's size (especially when compared to modern pocket pistols) and the single-action hammer is very stiff (especially when compared to single-action revolvers like the Ruger Vaquero). Breaking the barrels open is very stiff as well (especially when compared to other derringers). She only has a half-inch of rifled barrel where the 2.5" shotgun breach stop is. Will also fire the substantial .45 Colt cartridge and the recoil is not as punishing as I thought it would be. Some .410 shotgun cartridges load 3 or 4 000 buckshot or slugs or compact metal discs, but many of these self defense .410 loads are for the 3" cartridges and larger derringers that load them. The round rosewood grips are nice and they fit my hand nicely even though the handle is so small. She has a hammer-blocking safety button (important!) and very rudimentary sights. Back when I bought this, in the early '90s, they were around $100, in I remember right. Now, they are $500! Ludicrous! But they chamber the 3" shotgun cartridges, so you get that.

For conceal carry, the Double Derringer is not bad, but you only have two shots, but those shots are substantial.

For pocket pistols in .45 ACP, there are many to choose from. Glock 36, Colt Defender, Sig Sauer P250 Compact, Kahr CW45, and the expensive Kimber Super Carry Ultra HD.

In the battle of concealed carry firearms with the slimmest profile, the Springfield XD-S has taken the crown. With its 0.9 inch slide width, it has overtaken the KAHR pistol as the concealed carry .45 caliber pistol with the slimmest profile. It comes in 3.3" and 4.0" barrel lengths.

My go to summer carry is my Shield .45. Winter/heavy clothing carry is my Sig P220 DAK. Although the Shield is small, it's not pocket carry small.

> While you are correct aren't there rounds that have a track record of achieving one shot stops much more often than others. Like .357 magnum, for example? Isn't it the same for shotguns? Or is it just hearsay?

Now we're not saying energy isn't important, but that it's only one factor. Shotgun energy is on a different order of magnitude. It's got a shitton of mass and some decent velocity.

  Here's a video I did 10 years ago. (Holy fuck.) Notice that not much happens until you get to real rifle rounds and the back gets blown out of the paper. And then the two shots with the Mosin, the first with FMJ just punched a .30 caliber hole. The second round was a soft points blew the fuck out if it.

Same muzzle energy, different effect on target.

Speaking of fucked up ballistics...

Franklin Reformation gimmick or useful?

Major gimmick. I guess 950fps isn't THAT much slower than the 147 grain RA9Bs I like that tend to push just right at or under 1000fps, but I don't see these +M hollow points (although that's a pretty clever name from a branding perspective) expanding wider, penetrating deeper, fragmenting widely, shattering pelvises or magically exsanguinating bad dudes faster than the RA9Bs that I pay under $.50 a round for. Handguns suck pretty equally. If the expected use case for these is to penetrate deeper for dangerous game or something, I wouldn't choose 9mm to begin with.

We used to use heavy bullets because we were limited by black powder. Then the entire world, with all of its empirical data and real life experiences, transitioned to lighter bullets pushing higher velocities for just about every purpose.

I'm only interested in these as a testing ground for two-piece cartridge casing. That seems neat.

>>108296
Funny how all these weird NFA regulations spawn guns that are tailor-made for massacring civilians and just about useless for anything else.

  It's getting more expensive, lmao.
Still, what a cool looking piece.

That's cringey as fuck, though Ian and Karl's bertstare during the introduction was gold. Pity it's not based on a 1911, because I feel like boomers would eat that shit up (if they could afford it).

I know it's silly and the ammo will be very hard to find, and eventually impossible, but it's such a great looking gun that I want one. I don't want one enough to pay for it, but damn.

22lr

That's adorable.

I've heard it's a single shot. As sweet as that looks, if it doesn't feed from the magazine I'm a lot less interested. I mean, it doesn't look that hard to hide a CZ455 magazine in the Mosin magazine profile.

>>108197
It looks like a cricket barreled action with sights in a Mosin stock.

>>108201
Yeah, that's a bummer. I was hoping for something like the Norinco TU-KKW CZ clone I had, but in Mosin form.

>>108078
I'd still want to see tests. Buy one, put it in a backpack and fill the backpack with sand. Then shoot it with a powerful handgun and see how it performs. Also, it won't stop rifle rounds, which you will need a ceramic or steel plate for.

At a minimum, tell your kid to turn the backpack to the front during a shooting. Textbooks will do a lot to slow/stop bullets. From experience, 2 inches of phone book will stop a .22lr round. Obviously something like a .50AE will still be lethal, see the woman who got charged with manslaughter for killing her boyfriend after he asked her to shoot him in the chest with a Desert Eagle (while holding a book).

I'm not sure if "Ballistic Level IIIA Lab Tested" actually means anything. Since these are probably meant to be sold off to scared mothers, I'm guessing they used as little kevlar as possible to theoretically get to IIIA level and then skipped on the expensive process of actually getting anything NIJ certified.

They could still work but I'd want to see results for myself.

>Don't think I'm trying to dissuade you from this project

Haha, bless your soul man. I'm from a no guns country and have no machinist skills, just a blue collar office guy. Just thought maybe somebody maybe already tried something similar or knows about it.

If it were me doing a big bore rolling block, I'd be tempted by building a 10 or 12ga mag/supermag with slugs.

Comparatively much lower pressure and you've still got a big bang with a monster piece of lead going down range. Would be handy for stopping a charging waterbuffalo too.

>>108108
It would be cool to do what this dude is describing https://www.youtube.com/watch?v=-sWnqIspa9o but in rolling block action.

>>108109
I mean, yeah, but effort.

.244 H&H is a thing.

That´s a rifle round though, no? Smooth-bores are interesting in that, as the guy said, they don´t swage the bullet and don´t heat up as much and the length of the bullet not being an issue since you don´t have to figure out the twist rate. You can theoretically go crazy with hard exotic alloys since you don´t have to machine the rifling.
