Crisket Issue

I need a little help from the Cricket community. I rebuilt my gun with all new o'rings and reassembled. Everything is working perfectly. Trigger is great and everything seems right. However, it shoots high. I have the rear adjustable ring adjusted all the way up and the scope turret adjusted all the way down. And it still shoots about 10" high at 10m. Could someone point me in the right direction as to what to look for? Everything looks square to me.

Yep, swapped front to rear, tried different mounts. Tried second scope. Tried without the shroud. Still shoots high. 

With the barrel aligned with the little dimple on top of the barrel with the screw hole for the rail screw (as per E.R. video) and air-tank and the barrel look parallel. The scope (either one) looks tiled way down at the front. Still shoots a mile high. Could I have damaged the barrel while cleaning with a nylon brush and fiberglass rod from the breech?

And no I wasn't having this problem before I took it apart. It seems like something has to be out of alignment really bad, or I have damages the barrel somehow.

PS,, If I choose a POA and shoot at it every time, I get a stack of pellets about 10" high. Oh, and way left.

The rings are FX no limits. The other set are UTG. Both scopes shoot perfectly on my other guns. In face, one of the scopes is the one I had on before the tune-up. It shot fine then.


 
Is the barrel parallel with the pressure tube? The only other thing I can think of is the crown on the barrel was damaged somehow, but it wasn't like that prior to your rebuild, correct? Sounds more like a scope mount pic rail alignment problem than a barrel or scope or scope ring problem. Did you remove the pic rail at all during your rebuild? Maybe it was shimmed or something when you got it, and that fell out or something? The pic rail should be parallel with the barrel obviously for the Cricket.

That is correct. If the crown is damaged, I did it during rebuild. But if the crown was damages, would it stack pellets like it is? I'll go see if I can get a picture of the crown.


 
Nah, its really hard to damage that just with normal handling, plus it wouldn't stack pellets. Like I said above, it sounds like the pic rail isn't level. I'd remove it and check it out, see if there's something preventing it from mounting level.. Post a photo of it from the side showing the pic rail, scope, rings, barrel and pressure tube...

Yep removed it. I also put a square on it and it seems level. And, how would have changed during rebuild? I didn't do anything to it.

Also, just measured between the barrel and the airtube at the breech, first clamp, second clamp and muzzle end. All .334. So it looks like the barrel is parallel to the tube. I can't get a good look at the crown with the camera. but it looks fine. The crown is the only thing I can think of. 

Maybe I should push a pellet through and see what it looks like.


 
Yes that’s not too clear on your scope mounting and adjustment. I can’t see how you could have damaged the barrel but if it’s shooting high AND left and you have no other air leaks or symptoms of malfunctioning Id have to think it a possibility .

If you eliminate the scope and the mounts I’d take the gun apart and reassemble.

What could cause this? 1) Sight or mount alignment. 2) some misalignment in assumbly 3) barrel significantly damaged. 

Can anyone think of something else? 
 
Hi, My name is Crusher, and I am a WingNut....... sheesh. C'Cut had me check the geometry of the scope and I just did it backwards for some reason. I have set up literally 100 scopes. I don't know what went wrong this time around other than it has just been one of those days.

This Cricket is shooting very well and stacking pellets at 25 yards, no problem. I have it shooting about 850 fps with an ES of around 14. I bet it would be even better if I knew what I was doing when I cleaned and re-ringed the regulator.

But now, I've had this gun apart completely, well except for the little part behind the cocking plate. But I did take the trigger apart and put it back together. And adjusted the trigger to major sweetness. I know my Cricket inside and out now. :) Sweet.

The barrel was black and had rust. It took several scrubbings with Corbin to get the junk out. Let's just say this gun was the dirtiest I've ever seen. The airtube had something that looked like white silicone grease in it. The hammer spring, hammer and HS chamber were all rusty. Polished the hammer, spring and cleaned the chamber to spotless. When removing the hammer, I had to bang the back of the gun on the table to get it to dislodge. Now it slides like butter. Now it shoots in the 850's with the HST about half in instead of all the way in. I think the junk in the hammer spring chamber was slowing it down .


 
Nice job Wing Nut...! You got the short end of the stick on that purchase, at least initially. And if someone other than you had bought it, that didn't have your mechanical skills, it would have been a majorly negative experience. But now the gun is totally resealed, all Viton O-rings, firing valve cleaned and polished, regulator disassembled, all parts cleaned and polished, O-rings replaced, HST, hammer, etc. cleaned and polished, and trigger cleaned and adjusted. Not much else left to do, and the little Cricket is good to go for years to come. And, now you know your gun inside and out, which means you also know Vulcans and Taipans inside and out. 14 for an ES isn't bad, and it'll probably get better as you lead in the barrel and shoot it more. The reg. that you rebuilt and polished the washers, super clean barrel, firing valve and spring cleaned, etc. needs a little time to break in. Try shooting a string again after a tin of pellets, and adjust the speed to right around the 865 to 870 fps range. Now take it to your club this weekend and beat all those RAWs and Thomas guns in the 25M BR... ;)

I'm going to send you a new Hammer Spring, since the one in there was very rusty, and even though you cleaned it I'm sure its weak, since half way in with stock reg. pressure should shoot around 900 to 910 FPS. Once you install the new spring you won't have to turn the HST in very much to get to 865 FPS...
 
Thanks intenseaty

That part where the probe resides is still a bit of mystery to me. I didn't go in there. I replaced the side plate with a locking side plate from DonnyFL and saw all the stuff but I didn't mess with it. I'm sure it isn't a nightmare. Just unfamiliar territory. I'm sure once you look at how it comes apart, it is as simple as anything else on this gun. I've never seen the insides of a Cricket and I took it apart, cleaned everything including the air tube and installed new orings. All of them. And put it back together is about 90 minutes. That includes cleaning the hammer and spring chamber.

Next is polishing the Belleville washers :) And building my own moderator out of the stock shroud.

So Wing Nut, how's it shooting, and are we going to hear about your little Cricket beating the RAWs and Thomas guns this Sunday at the 25M BR tournament...? ;)

All joking aside, great job with the Cricket!!! Don't downplay your mechanical skills, many guys would have been lost doing what you did. Now the gun is practically new, and it'll be easy to maintain, and fun to shoot. I know you have a Red Wolf, RAW, and Crown, but I'll bet when you pick up a gun to go shoot just for the fun of it you'll pick up this Cricket more often than not. Its the same for me, and even though I have a few "high end" guns, when I pick a gun out of the safe to shoot, its almost always the Cricket or the Mutant...
