Tuning KalibrGun Cricket II Tactical Barrel Reinstallation. Trigger Adjustment. Tuning.

[TTBJ]

update. All done, the torque are:

A = 15 in.lbs with Never-Seez, It's enough to hold the barrel tight.
B = 20 in.lbs with Never-Seez
C = didn't touch it.

 

[TTBJ]

Adjusted trigger blade placement, from position a (cocked)/ b (uncocked) moved to c (cocked)/ d (uncocked).

For adjustment, disconnect #77a from #63, then turns #80 trigger rod AND #77a together. (= keep #77a & #80 in place, only #77b moving front or rear.) If turns #77a then both trigger blade placement and 1st stage trigger pull force will change.

 

[TTBJ]

Adjusted 2nd stage trigger travel.

2nd stage trigger travel = engage length of top and bottom sear. This a my hunting gun. For safety reasons, I set it up a little bit long. If you want a "hair" trigger, asjust it shorter.

After 2nd stage trigger travel adjustment, the cocked trigger blade placement will move. So if you want full adjust the trigger, do this step first.

 

[TTBJ]

Adjusted 2nd stage trigger pull force from about 8 oz to 14.5 oz. Now I can feel the 2nd stage clear.

8 oz is too soft, almost same 1st stage.

[TTBJ]

Adjusted 1st stage trigger pull force a little bit heavier to about 9 oz.

For adjustment, just turns #80 trigger rod to move the #79 lock washer front/ rear. Do not cut the #78 spring shorter.

 

[TTBJ]

1st stage trigger travel is not adjustable.

The stock is only thing need to remove. I removed both.

Next is hammer spring adjustment.

 

[TTBJ]

Removed the adjuster to made marks.

3 x 29 = 87

Done

Speed testing. With JSB 18.13 gr, hammer spring adjuster fully screwed in = "0" turns.

959 fps at 4 turns out (counter clockwise)

942 fps at 4 + 5/29 turns

896 fps at 5 turns

 

[TTBJ]

Finally set up at 4 turns out, 959.4 fps/ 10 shots.

This is where the hammer spring adjuster ended up at 4 turns.

@mcoulter got 960 fps at about 2.6 turns with FX 18 gr.

Cricket 2 Tactical .22 Long hammer spring testing

I tested velocities on my Cricket II Tactical (600 mm barrel) the other day. Here are the results: With FX 18 grain pellets (at about 64f) I started with full tension (hammer spring adjuster fully screwed in = "0" turns) and went from 1029 fps down to 733 fps at 7 turns out (counter...

I bought the Cricket II Tactical 60 off of the forum. The barrel is loose, it rotate when screwing on the shroud. I can easy rotate the barrel/shroud just by 2 fingers.

After some homeworks, now I know how to do it.

The front/rear clamps are only parts to hold the barrel. Screws (A1/A2/A3) are used to tighten clamps to hold barrel and air tube. The screw is M4x16.

The barrel has a little dent, set at exactly 180 degrees of the barrel port. When fitting the barrel, this dent must be seen through the front screw hole in the picatinny rail. This means that the barrel port and the transfert port are exactly aligned. A pointed barrel locating set screw is used when installing the barrel. It is then taken out once clamp is tightened and is replaced with a normal bolt. The front picatinny rail screw (B) is M4x25, so the set screw is M4.

My questions are:

1. the set screw is cone point or cup point?

2. torque for the 3 clamp screws (A1/A2/A3)?

3. torque for front picatinny rail screw (B)?

4. torque for rear picatinny rail screw (C)? It's M4x20, 5mm short than front screw, only about 3mm thread in clamp, right?

Thanks
