Title: Chinese B3
Post by: Ghosth on March 12, 2017, 07:03:14 PM
My wife has been gone for 5 days, quick trip to see her daughter, and our grandchildren.
Yeah I am husband #2.

So I have had a lot of time this week to think, to tinker, to find stuff, parts, etc.

3 years ago I bought a pair of the cheap Chinese underlever .22 airguns. Still have one in the box. The other one well I will admit I have had a bit of a love/hate relaitionship with it.

But then 4 days ago after running a couple of patch's through the Hatsan 135 QE Vortex beast. I had a thought. I don't know that I have ever cleaned that barrel.

So since the tools were out, I ran a couple of oily patch's through it, then dry, then oiled, then dry.

Then fired a few shots. First one desieled, you could smell it. But the next three pellets were all in a nice tight little cluster. Tightest I have ever seen out of this rile.

Essentially they were one triangular shaped hole.

This was with the original iron sights which IMO are ok, but not terrific.

So I went looking around and I found a one piece offset dovetail mount that would hold a 25 year old Simmons Red Dot sight given to me by my father in law.

Now I struggled for most of a day with this thing. Turrets were all the way up and all the way right, fought and battled until I got smart. Turned the left right until it lined up with the center of the front sight. Did the same for elevation. Then started shooting 3 shot groups of CPHP's 14.3's. Then make an adjustment, group, adjust.

When it happened it totally took me by surprise. I was shooting at a printed target, with 5 small black bullseyes on it. I had just put a fresh target up. Fired 3, and my pellets were no where in sight. Getting up I walked down to look and to my absolute total amazement. They were hiding in the bullseye, in a nice, tight, triangular hole dead center up down left right. We were zero'd.

Whew, that was work. Now for some fun.

Each of my home made spoon spinners got hit for a zing. I have an electrical outlet box cover, steel with a target in the center painted on with finger nail polish. Yellow circle, then red, then blue, with a small white out dot. Popped that a few times for giggles.  Makes a lovely CLANG sound.

Then punched out a few bullseye centers just for kicks.

After 3 years of love, hate, and apathy can you really expect me to believe that just a little bit of love, oil, cloth and a cleaning rag turned this so so quarter to sometimes golf ball sized groups shooter at 20 feet into a tack driver? Really?

No it does not replace the Hatsan 135 QE Vortex, nor even old blue my old Sheridan Blue Streak that we have so much history together with.

What it does do is give me an option. If I don't want to crank the big beast, I can easily put 5 through this girl without giving my arm a workout.

So word to the wise. Got some time? Got a hanger queen that needs some love?

Might want to give it a try.

ps anyone ever convert one of these to vortex? Anyone have any clue which one would give reasonable power, smooth out the shot cycle  without costing an arm and a leg?

Here's a shot group with mine. This is a shot group from my 117cal B-3 Under Lever taken last Oct 19. The center ring diameter, on the 2in Birchwood Casey stick-on target, measures 1in. In the 2nd picture of this shot group, I was able to cover it with a dime. The range on this shot group was 30yds. The distance was measured and marked with a 100Ft tape. The pellets that I was using were Crosman 7.4gr Premier Pointed Pellets.>>>>I have read (Only Read About This & Have No Experience with mods on this one) that going for a lot more power and pellet speed leads to Big problems with the light duty Trigger Assembly. Hopefully Other Members Here can "Enlighten" us both on Power Up-grades with the B-3.   Mine is completely unmodified with all of the original parts.

Those B3's can be a diamond in the rough.  I have several of them and each one was a pretty darn good shooter right out of the box, however I did a full tune on each one and then they really shined  :)  They really respond well to a tune with increased FPS, smoother firing cycle and incredible accuracy.  All of my B3's have taken their fare share of small game and pests  within 30 yards and they are a joy to target shoot with in the backyard range.   We used to hear a lot about the B3's owned by our members,  but not so much anymore.   

Anyway, congrats on getting your B3 shooting the way you like, they really are fun guns  :)

Does any one have information about serial number dating the B3s?

I just bought and received a version that seems to be the B3-1. It is used and beat up but it works.
I havent had the chance to do any kind of accuracy testing so I dont know whether I have one of those rare gems in my hands. After some testing I can say that this one shoots cleanly without buzz and twang but cocking it feels like cutting through gravel with a kitchen knife. Also, the trigger isn't terrible at all.

So far it looks like a 30€ well spent. It will be a gun to practice airgun surgery with.

Anyway, I would love to know when it was made. The serial number is: A411592

Along with my other rifles I own 6 of these B3's. I enjoy each one of them, as they were all accurate after I cleaned the barrels. Mostly I did a lube tune and changed the springs out on 4 of them and they are really good inexpensive shooters. I had a rear spring guide self destruct on one of them, and replaced it with a B19 rear spring guide and spacer, sort of redneck engineering but hey, it works great and is a good shooting gun. Mostly they react good to a tune job. Clean it up lube it and shoot it, can't beat it for the price.

This thread inspired me to dig out a B3 I had stored away in a closet.  I cleaned the barrel (filthy!), popped on a Hawke AirMax scope, grabbed some Superdomes and headed to the back yard.  I was stoked!  I was even more happy when the first shot showed the windage was dead on and the elevation was only off by three or four inches.

Then, the first group at 22 yards --about four inches-- was definitely a buzz-kill.  I kept shooting for a while but things didn't settle down.  I had to take several shots with my TX200 to help get the bad taste out of my mouth.   ;)

I have another B3, new in the box and unfired.  I bought an armload of them years ago for something like twenty bucks apiece from the local volunteer fire company's tool sale.  I gave all but two of them away as gifts.  I'll give the remaining new one a try and hope it's better than the other one.

The rifles have no brand or origin markings at all.  The box says "Pellet Rifle"  "No.4110"  "Type B3."

Tight groups,
Bob

Mine for years would alternate between quarter sized groups to silver dollar size, with no real clear indicators that it was pellet related.  I think in my case I did 2 things. I shot it off and on, and shot it, and shot it. and broke it in, gradually, over the course of years.

Then I cleaned it. I think I shocked it.

We'll see how long it behaves.

I no longer own the B3 I bought years ago when living in West Virginia but it was a shooter after a few mods like adding an oring sealed piston cap.............
When iron sighted I shot this 25 yard target............

Actually, I bought two from a Cummins truckload sale for $19.95 each and put together one B3 from the best parts. LOL.....my B3s were definitely a product of "file and hammer" production!

Then I stripped off the riveted on "irons" and mounted a 6x Burris Compact scope that cost 4x more than both B3s together............

Here is a 25 yard target shot with the above...........

These little "gems" can certainly be made into shooters with a bit of luck!

I guess I'll have to set aside to time to tear the B3's down and tune 'em up a bit.  Maybe I'll JB the bores while watching some TV this evening.

For twenty bucks, they're pretty amazing, really.  Think about it... that's cheaper than two tins of decent pellets!

Tight groups,
Bob

Definitely worth the 30€ I paid for mine!

I found the gun to be very easy to open up and smooth out. A simple filing/lubing procedure made quite a difference. I cannot believe how cleanly it shoots. Cocking is still a bit rough but better than before. Im sure I can make that better too with some more work. All though, after seeing the quality of innards this became the only air rifle with which I actually use goggles. I dont trust it a single bit.

I also stained it almost black. What do you guys think?

LOL....indeed easy to open but watch out for all those sharp edges and have a tourniquet handy just in case!   :o

I used a metal rear spring guide assembly from a Crosman Storm XT springer to replace the plastic one that shattered. Smooth cocking and a simple bump cycle without twang now. Tomorrow I will be able to chrony it and see the difference in velocity if any.

You might want to check and see if your Tetanus shot is up to date before you start working on a B3.   ;)
