MCA sports makes adapters to shoot 7.62 x 39 from a 308. Anyone try these.. do thety work in Handi Rifles??

It has been discussed several times. Do a search on it and you will pull up a few. I ended up with one, a 32ACP for 30-06 but due to lack of ammo I was unable to try it out.
Seems the guys at MCA are hard to get ahold of from the last I heard.
I too would like to try one out for the 7.62x39.

I have one in .22 insert for the BC 45/70 and it works great.

You've confused me kitchawan. I can see shooting a 7.62 through a .308 barrel since both bullets are the same caliber (same bore diameter). But how can you shoot a .22 caliber bullet in a .45 caliber barrel? Seems it wouldn't contact the rifling and the bullet would tumble.

What it is ,is a .22 cal. barrel insert you fit inside the 45/70.I use it when all shooting is inside at 50 ft.sight alinement,trigger control and a lot cheaper that 45/70.

The inserts are a bit different than cartridge adapters, they have a short section of rifled barrel attached, Larry made a 22 Hornet insert for me that fits in a 12ga shotgun, in my USH it shoots ½" groups at 50yds which is as far as I've tested it, the thread below is in the FAQs.

my machinest and i made one a couple years back for a .380 round...
it worked!!!

, i'll have ta dig it out and show y'all.........if i can find it.
them lil thangs can grow legs and walk, if ya don't watch-out......

i kinda lost interest in it after we made a 17" barrel for a handi use'n the .380
it was certainly a tack-driver @ 25 yrds, it'll peter-out after that tho.

I have quite a few adapters of different kinds... Here's how my 32acp/30-06 adapter shoots,

The problem with a true chamber adaptor to shoot the same Cal bullet as the rifle it really chamberd for is that the neck portion of the chamber adaptor is really thin, like not much thicker than the neck thickness of your brass. Seems in lots of cases the neck finally fails and stays stuck in the chamber, then you have to figure out how to get it out. It would be a piece of cake to make up a simple one for a, say, a Hornet to .223, but why would you bother? Larry

That's not completely true... Some adapters don't even have a neck, the case of the small round sticks through the adapter, so there's no neck needed...

Now there is a great design. The bullet is trusted to just fly straight down a hole that is about .035 inch larger than it is? I am surprised that some don't turn sideways and get stuck right there!

There are a lot things that can be done that shouldn't. I guess if all you want is for some metal to come out the end of the barrel in some fashion then they are a good design. I may just have to whip one up, how about just making up a 22lr adaptor with the rim offset and the pointy end centered and let it turn the corner to go straight when you shoot it in a CF chamber, that would be just about as as odd as an adaptor with no neck.

Perhaps you should see one before you pass judgement on it... Could it be someone thought of something that you didn't, that actually works??? AND, there ARE some high grade VERY accurate 22rf adapters that are off set so the centerfire fireing pin hits the rim. Once again you need to SEE how one works before you pass judgement, as they have been made for many years, and are of the highest quality...

I believe I think fairly much out of the box on most of these things. I have seen a lot of this stuff, I've seen some RF adaptors that use a type of transfer bar to fire a RF cartridge from a CF chamber, I have even built one for shooting a 22 Hornet from a 12 Gauge chamber, and it included an ejector in the adaptor, some work reasonably well, but the one thing they all have in common is attempting to make a round fire in a rifle it is not designed to fire in. My guess is that if someone sells it then it will probably shoot a bullet out the end of the barrel in some fashon, my point is that they are all compromises, they attempt to make something work where it is not designed to work. I think they end up a lot like a Car/Boat, or a Boat/Airplane, or a Car/Airplane, all of these things can be made to work but end up not being good at either one. There is a huge intrest in these things, making one that will put lead out the barrel is dead easy, doing it properly is not quite as easy however, and making one that shoots well and is practical to use without having to poke the empty case out with a nail is even harder. But, I guess if people want them I should probably knock a few out and see how they work, I am thinking like a 25 ACP out of a 25-06, at least in this State it would be legal to hunt Elk with.

You may be right when it comes to cheapo adapters, but if you are willing to spend the $$ to get a high quality adapter, they do every thing they are supose to do, and do it VERY well.

Take the offset 22 rf models that you seem to think are a joke. They go in and out VERY easily, are adjustable to the sights of the gun they are in, and ALWAYS go back to zero when reinstalled. Also, they shoot as well as a decent bolt action rifle. BUT, "these days" they aren't cheap to buy...

There have been lots of different adapters designed and built, you just can't throw a blanket statement over them all.

I know you like to try and make a joke of my post, but i was just trying to help out the folks here who have been less fortunate than i have, to over the years, have been able to own and use so many different kinds of adapters, many of wich i still own.

Anyway, i'm done with this thread.

I think we need to define "chamber adaptor" as opposed to "barrel insert", they are totally different things. If you are talking about a chambered barrel that goes inside another barrel of larger bore it is one thing, if it is a true chamber adaptor which shoots the rifles intended cal from a adapted chamber it is quite another. Which is the .22 adaptor you are talking about? Larry

I don't think you guys want to get too nit picky there about definitions and semantics.... relax, you'll have a more harmonious outcome. Let's just say that some may work well and other may not, some seem like a neat idea but others beg the question of 'why would you do that!' I don't think I would buy one to count on getting my breakfast with, there are too many other options. I can see the attraction of a 7.62x39 in a .308 though. And I'm sure some of the better ones work well but for the price of them, it wouldn't take much more to step up to a used Handi instead. Nice idea though IF you have a lot of handgun ammo around that you want to shoot up. Of course now days, you would be better off to take that ammunition to a gun show and sell it and go buy a NEW Handi! But that's just my opinion. If you want to try one..... why not! As long as we are shooting, we are having fun! 44 Man

i once saw a barrel insert for a shot gun
12gage can't remember brand but it was brand specific

a 45-70 screwed into the choke tube threads of their coach gun double

they were out of stock then i lost the info

any one know of this??
seemed like it was under $600 for a gun and 2 inserts

i have used a 22lr in a 222 adapter in a t/c contender
good short range pest control

trotterlg · « **Reply #18 on:** September 14, 2009, 12:33:34 PM »

I can see the barrel inserts working well, the one I made up for Quick seems to shoot amazing well. I just cannot imagine a pure chamber adaptor shooting well at all, with a throat that is 2 inches long with a gap in the middle seems to make it an unlikely prospect for accuracy, I am however going to make up an adaptor for a 25 ACP into a 25-06, now if that works out then I may change my opinion of them. Quick, do you have a 25-06 Handi? Larry

I bought a .32 acp adaptor for my .303 British sporterized with scope rifle that I've had for over 40 years.

It's one that looks just like a spent .303 casing, and you eject the adaptor of each shot, and dump the .32 casing.

It did take some polishing to get it to fit, and slide in and out without getting stuck in the chamber because of the coating they put on the steel, so keep that in mind and don't try to force it into a chamber if you have the slightest resistance or you may not get it out without damage to the adaptor.

I bought it just for the fun of it and to see what it would do, and I'm impressed with the accuracy at 25 to 30 yards, which without moving the adjustments on the scope it would make a perfect small game rifle.

You can then eject the shell and put in a full house .303 for larger game, and be still dead on since you didn't adjust the sights.

It would be great to carry along on a backpacking or survival senerio where you wouldn't need to lug around two rifles, just an extra box of .32 acp cartridges.

I also shot it out to 80 yards and with a little Kentucky windage you can hit a basketball size target with ease.

Good luck trying to contact that guy at MCA sports, as I gave up on him and bought it from one of those shooters mail order catalogs you get in the mail.

Some members of my club use .22 inserts in their .45 revolvers for low cost shooting at an indoor range.good practice for cowboy matches.
