Is the Striker, 1000 or webley valuemax based on the b19 platform

[Bullpuppy]

Hi, I searched the crossreference's and could not find if the the chinese models that the hatson strikers are based on. Are they a variant of the b19?

[SteveP-52]

They may well be as my older VMX's are pretty similar to the Crosman Optimus I also have. The newer version Striker/1000/Edge and VMX rifles change a bit as all of them have a newer version one piece cocking arm that's less susceptible to bending or breaking being solid and a lot thicker.

     I don't think any of the B19 parts are interchangeable with any Hatsan, They are simular as they have a compression tube and piston and spring, but that is about it. Just my observation and seeing if any parts would interchange.

Do they locate the barrel with flat washers or shoulder bushings? Does the sear grab the skirt or a center rod? Is the barrel latch a wedge or a ball detent?

I guess those questions would help out the rest of us who have never had a Hatsan. Thank you for your insight thus far.

The Hatsan has bushings, the sear grabs the piston skirt, the barrel latch is a wedge. The same as a B19/B18 design used by Chinese manufactures. But the dimensions are TOTALLY different so no I see no way short of machining to make these parts interchangeable.

Perfect. Thank you for the info.

I think we are at least a generation removed from the English way of building a springer being as ubiquitous as the Gamo way or the Diana/Weihrach way.

Understand that Hatsan is bringing that back.

i hope that is correct...good info !!

Sorry to mislead. My intention is just to say that Hatsan seems to be growing in popularity, and apparently they build break barrels a lot like Webley did.
I'm not intending to say that Hatsan is going to build rifles in the UK or employ Brittons to build rifles- that wouldn't make sense with labor costs and all.

not misled, i knew what you were talking about...only wish they would use
webley design and craftmanship.
but they are getting better from what i have noticed.

Very similar (B18/19 to Hatsan Striker) in design. The triggers are also the same-ish ("Gamo-trigger?"), although the sear spring is lighter than the same spring in a Crosman trigger group. I found that installing my Welsh Willie trigger in a Striker required a stiffer sear spring, which I sourced from a Crosman trigger group...dropped right in. I've never tried to swap a Striker trigger group for a Crosman, but I suspect that would be a no-go (at a minimum the Hatsan trigger is much longer, which is why a CDT trigger won't work as a replacement...doesn't extend far enough into the trigger guard to be viable/safe). Also, the air tube diameter (and length) are different. Hatsans are larger diameter (27mm seal vs. 25mm seal in a Crosman), and just by eye-balling it the Hatsan tube may be a few mm longer in available "piston travel." Barrel blocks are different, so no interchangeability there either as far as I can tell, and all modern Hatsans now come with the one piece cocking arm. Many have replaced the Vortex piston in their guns with Crosman Nitro Pistons, and said it was virtually "drop-in." They have also replaced their springs with the same NP unit, but that requires some fabrication of parts in the rear block to locate the piston. I'm pretty sure you have to modify the rear block of a Vortex set up too, though I have never done it.

Well, thank you for your thoughts.

About the trigger, I imagine a cdt trigger would just need a “shoe” to drop it down for a Hatsan? But that would add leverage and change the geometry.

The CDT trigger fits just fine, I've done it, you just need a way to lengthen the trigger blade another 1/4 of an inch or so depending on how long you want it. Shouldn't change the geometry any or if it does, I wouldn't think it would be by much.
