Hi there
Someone knows this brand of barrels?
cold hammer forged and sub moa precision

All are fairly FAST twist for the air guns being @ 15"-16" to 1
being a RUSSIAN company ... tough one here in the USA unless brokered threw someone who knows the politics of importing such goods.
In recent years most of the European distributors NO LONGER will sell barrels to us ... kinda suc ks :P

15" in .177, 16-21.5" in .22, 15-18" in .25. Looks like slug barrels and pellet barrels.

Groove size for .177 is .180"....so oversize by .003"
Groove size for .217 is .221"....so oversize by .004"
Groove size fot .250 is .254"....so oversize by .004"
(Lothar Walther also has the same .004" oversize for their .217 and .250, but their .177 is .181" compared to Precision Alpha's .180".....but then the Lothar Walther (and the Alpha Precision) powder burner barrels are not oversize. For some reason there is a trend in airgun barrels to have oversize groove diameters. More examples using .217 ---> https://www.gatewaytoairguns.org/GTA/index.php?topic=170581.msg155916675#msg155916675 (https://www.gatewaytoairguns.org/GTA/index.php?topic=170581.msg155916675#msg155916675) , https://www.gatewaytoairguns.org/GTA/index.php?topic=170537.msg155915511#msg155915511 (https://www.gatewaytoairguns.org/GTA/index.php?topic=170537.msg155915511#msg155915511)
P.S. The first link I provided has two references to undersize groove diameters (.214" and .2155") for .217, but mostly the trend is for oversize for whatever reason? Maybe oversize works better with the skirts of pellets?

Here are the specs on the two Alpha Precision .30 caliber barrels:
1.) .306" groove diameter, .299" bore (lands), twist is 1 in 16.5".
2.) .309" groove diameter, .298" bore (lands), twist is 1 in 16".
Both 27.5" long.
Compared to....
Lothar Walther .30 Air gun barrel is .298" bore (lands) with .306" groove, twist is 1 in 16".
Lothar Walther .308 powder burner barrel is .300" bore (lands) with .308" groove diameter.
Hmmm.....those .30 Air gun barrels (from both Alpha Precision and Lothar Walther) are considerably oversize on groove diameter as well. Makes we wonder if shooting .308 lead slugs is not such a bad idea for these .30" (should be .300" groove diameter) Airgun barrels. Certainly the twist rate is there to stabilize a decent amount of projectile length.

Edgun uses them for his Russian customers. The link above is one of his reviews on them, he has others.

Specs on the Altha Precision .35(9mm) and Lothat Walther .357:
Alpha Precision : .355" groove with .349" bore, 1 in 15.35" twist
Lothar Walther : .355" groove with .349" bore, 1 in 16" twist

That is the first thing I thought when I saw them!
I'm thinking that .177 would make a heck of a good little slug barrel, and I'd try one, if I could get my hands on one.

1 in 15" for .177 is about equal to a 1 in 18.5" for .217.
Yep, that is not too bad for the current Nielsen slugs.

Two months ago they mentioned a US office would happen in 3 to 6 months.

I'll certainly start paying attention, when we can get one. Until then... it's just hoping ;)
-
Alfa Proj 10m Competition pistol, anybody? I bet one and the same.
-
Could be....would be Czech Replubic vs Russia.....but could be the same barrel maker.

I know this is dragging up an old one, but hopefully I’ll have a .22 barrel with a 17 twist coming soon. Just depends on the money wire. Stay tuned.

I'm glad you brought this up Rich! I'm playing with their .177 barrels currently. I have the 14.6" twist standard rifling and the 16.5 twist polygon. I'm not done testing, but they definitely have their strengths. The quality is top notch!
I wish I had remembered this thread, so I could have commented sooner. Your post just brought it to my attention again. I'm guessing you probably dealt with Maxim at Alpha? I managed to get him to send my two blanks with a barrel order for Edgun West, then I had Brian at EW ship them to me. I paid Brian at EW, as opposed to wiring the money straight to Alfa. They are a legit company, so I'm sure you'll get your barrel shipped just the same. I think the biggest question will be if your barrel makes it through customs. Hopefully, you won't have an issue there. Brian informed me he would have no problem getting blanks for people from Alfa included with his barrel shipments, fyi. It isn't as quick as calling up LW and getting a barrel, but you should get it just the same :) Brian also told me he can get them machined for some guns, but you'd have to ask him which ones. He told me, but I can remember all of them.
Specifically, which barrel did you get?? Polygon is the only one they offer in 17.7" twist I believe. I wouldn't mind getting my paws on their 16" twist .22.
I'm sorry I didn't add to this post sooner guys :-[ I did mention it on my "special" .177 barrels post though. I hope some of the info is useful.

Well, the wire goes out tomorrow. Hopefully it’s actually going to Alfa. I opted for the polygonal barrel. I think it might get obligated to the Kral Knight. I’m just diving into the airgun barrel thing, so I have much to learn, like anything having to do with cutting a lead and such. I’ve done quite a few revolver and centerfire rifles, but never an airgun barrel. It’ll be a learning experience and hopefully I don’t run out of barrel before I get it figured out.
The guy I’ve been emailing with is named Mike Klimov. Hope he’s actually with the company and my email didn’t get hijacked.

I never dealt with Mike, but they no doubt have multiple people handling these things. One thing I'm figuring out is these barrels have a leading in process. Shoot it, clean it, shoot it some more, clean it etc. There's a video of Ed talking about it with them being that way too. They get better over time basically. You'll have a lot more wiggle room, if you're doing the leade for pellets. Slugs tend to be a lot more finicky about the leade, fwiw. Good luck!

I’ll get it figured out. I remember the first revolver of mine I re barreled. It is a .44 that I use for hunting and I started out with 12”, but ended up with a 10” before I got it right. 5hank goodness it was a cheap blank. It may take some trial and error, but I bet it’ll be a shooter eventually, might only be 3” long, but it’ll be a shooter. ;)
I did wake up to an email from them stating that they had received the funds and will get me a tracking number when the parcel ships.

If a dummy like me can do it, I'm sure you'll have no problems at all :D I figured they'd get you taken care of. I never had any problems at all getting in touch with them.

Hey Mike,
Got the tracking number and hopefully it won’t be too long before I have the barrel in my hands. Thanks again for working with me on this. Hopefully you’ll be able to get some barrels stocked here in the states eventually.

Good day, we get a warehouse in US but for now there are only firearms blanks.
And the quantity we sell from there starts from 20 pcs.

Mike, I'm still doing a lot of testing with two of your .177 barrels! As I mentioned earlier, I dealt with Maxim, and he was very helpful. I haven't provided him with a full update yet, because I'm still trying to nail down the results with the polygon barrel. So far, the slower 420mm twist polygon barrel is doing great with 15 grain .178 slugs, and the 370mm twist conventional rifled barrel is doing great with heavier 23/24 grain .1775 slugs. I suspect the polygon would do well with .1775 slugs too, and I hope to test that theory by this weekend.
The extra length has been helpful in making good power too, since our main source for barrels here is LW, and they only offer a 600mm barrel. I've managed to get the .177 as high as 58 fpe so far with the 650mm barrel :D

Yeap, we work with Maxim together in the same office.
Happy to hear that about our product :D
Please feel free to share your fire test with us via email. We will download it on our website.
Good luck!

Will do! I'm going to install the barrel in another gun for easier testing in the next few days, but I will give you guys a solid breakdown of what is working and what isn't, when I'm done :D

New testfire KrugerGun with Alfa barrel cal. 6.35mm lenght - 580mm
Distance - 105 meters.
Slugs - Katyusha 3.5g

Not bad at all Mike! I'm just finishing up the new gun to do some testing with myself. I should have a pretty good idea of how the AP 16.5" twist polygon is going to do with .177 slugs by the end of the weekend.

Mike, I got to do some more testing with the Alfa Precision 16.5" twist polygon .177 barrel today. It did really well with 22 grain slugs, but the accuracy went down hill with 23 and 24 grain slugs. So, that the AP polygon appears to be very solid for .177 slugs in 15-22 grain weights! The faster twist standard rifled AP barrel does great with the heavier stuff from 20-24 grains. If you would, forward that to Maxim as well. I have some lighter 12.5 grain slugs, but I'll need to test them later, when I have the power lower in the gun. At the current settings, I can't shoot them any slower than 1050 fps, haha. Anyway, that's the update.
-
Still patiently waiting for my barrel. I think it’s on a slow boat somewhere. The USPS tracking still says it was processed through a facility in Russia. Hope it gets here before winter.
-
Is there any news ?
i am interested in these barrels
-
I don't have any news on acquiring the barrels. The same two options remain. You can get it straight from Alfa, and hope the shipping works out. The other option is getting one through Brian at Edgun West, which I've heard lately can be a bit tedious as well. I don't know if he is just too busy with the Edguns or what, but...
I did test the polygon .177 with the new NSA 20.5 grain slugs, and it did very well with those. It appears the hard part is just getting the barrel at the moment :( It would be really cool if we could get some more US companies to be a distributor for the AP barrels. I suspect they'd sell a few!

Interesting read on the Alfa Precision Barrels.

Well then,we have many of the best barrel makers in the USA, good luck trying to find one that makes air gun barrels.
That said ,it has been pointed out that barrel reliners can work as barrels for PCPs,thus with some focused study one should be able to find a barrel that suits their needs made in the USA or countries Not sancioned.
Wow, the above was an interesting read...Which reminds of the saying ," Wherever there is a Will there is a Way".

Could be just the thing to light a fire under someone's butt, and get them to start churning out quality domestic barrels. At the risk of oversimplified the matter; how hard can it be? People have been rifling barrels for a couple hundred years. Surely with today's tech this shouldn't prove to be overly difficult. Or so it might seem...
-
All about cost. Thus if we,air gun shooters want barrels makers to make barrels for us it has to be worthwhile for them. We have to make it worthwhile for "them" to do it=get enough buyers to purchase the barrels.
We need an "EAR"to listen to our wants.That would take someone to take the time to talk to some of our USA barrel makers to go ahead ands see if it is worthwhile for them to make the barrels.
Another thought would be,there has been some USA barrel makers that did or do produce the air gun barrels.
Get a list of them and see if they are willing to do it.
I hope someone can interject more thought on this subject.
As far as making the barrels,the makers need to know what reams to make or use,plus do tests to make sure the barrels do what they are suppose to do=time and $$$$.
For slug users a thought: make the slugs fit the barrel to be used and not the other way around.
Another thought from a person that never used a slug,could you use an already made bullet,or does that get too expensive?
Thank you for thoughts on this subject.

Interesting, so my 26 year old IZH46M and the Alpha barrels in my Leshiy 2s are now part of Ukrainian Propaganda.
From your link: "The material was prepared according to the information provided by the Economic Security Council of Ukraine. ESCU is an organization created by Ukrainian business to counter the economic front of Russian aggression against Ukraine." Your Avatar gives your political bias away. THIS HAS NO PLACE HERE!

This is a old thread and the comments you guys are useing are not needed here so I am telling you to stop. I will remind you this is a airgun forum. David
