HATSAN 125 & 135 Owners - Help Needed !

[Tarheel]

To all owners of Hatsan 125's and 135's . . .

If possible, I need a few measurements for comparison between these two rifle models:


1 - Outside diameter of Piston Tube.

2 - Length of Piston Tube ( just the cylinder )

3 - Weight of action, by itself, when removed from stock ( no scope attached ).

4 - Type of stock & weight ( Conventional, Thumbhole, or Wood )

5 - Large, clear pics, if possible.


Thanks, in advance,  for your help !

I'm trying to determine if a 135 action will fit into a 125 stock and vice-versa . . .

I would get the info for you, but I am holding off on tearing down my 125 till I get the seal. I also want to put together a video to show what a bone stock 125 acts like after 250 shots through it, complete with sound ****TWANNNGGGG!!!!****
lol

Paul,

When I said "Piston Tube", I should have said "Receiver" . . .

I just need the outside diameter and the overall length of the tube to compare to the 135, in order to see if the stock inletting would have to be changed.

This would be part # 824 on the schematic

Wouldn't Hatsan tell you if they will interchange if you emailed them?  I'm thinking they are not switchable  I can't take mine apart but I'm sure Hatsan would say if they are two different animals.  My guess is the 135 is slightly bigger...

The only differences I have seen are in the internal diameters of the Receiver and the Piston / Seal . . . The 125 uses a 29mm Bore in the Receiver, plus a 29mm diameter Piston & Seal.

The 135 uses a 30mm Bore in the Receiver and a 30mm diameter Piston & Seal.

My "theory" is that the outside diameter and length for the Receiver is the same, differing only in Bore diameter and Piston / Seal Diameter.

I need to confirm this . . . Looking at the possibility of stock interchangeability.

I have tried e-mailing Hatsan on 3 occasions, but have not gotten a reply.

There probably busy ducking Syrian missiles.    Heard they fired a few over into Turkey.

Given the thickness and heft of their recievers, I imaging they could indeed save money by going a millimeter bigger on the bore for the 135 using the same tubes.

I"ll get full specs for you on the 125 in the next day or two.

Then I plan on showing how I put a gas spring in within two weeks;D

Paul,

Excellent, sir, I'll be looking forward to that 125 data !

Be VERY careful when working with the gas ram conversion . . . !

I still need a 135 owner to make a few EXTERNAL measurements . . . Please help me out here, guys !

1 - Outside diameter of Piston Tube.

2 - Length of Piston Tube ( just the cylinder )

3 - Weight of action, by itself, when removed from stock ( no scope attached ).
