Q:

Free float barrel on Cricket Carbine ?

I remember reading a thread about floating the barrel on a Carbine …I wanna say it was Greg who posted it but I’m kinda a fucking flake and can’t remember ..Any of you guys ever done this ? Does it benefit POI shifts . ? My gun shoots some badass groups but POI shifts quite a bit …it doesn’t shift a huge amount but it’s kinda like my old AirArms gun, just slowly shifts around up to like an inch or so at 45 yard s

I have a 22 and 25 BullPup Crickets.
But any time some says free floating barrel , I have night mares with my Marauder, Loved the gun , Pick it up sight it in and it would shoot with any gun I got, Set it down, breath heavy, Fart and the POI would change, I bought every thing they had three years ago to put on the gun,
POI would change if you laid it down and picked it up the next day,,,
I do not like free floating barrels, I hope I do not have one, :rofl: :rofl:

if there is an oring inside the barrel band (like the hw100) just take the o ring out from there, and check if no contact is made anywhere
thats it.

What is the barrel band that is cut off to prevent poi shift?

What kind of Cricket do you have ?
Some refer the Cricket rifle as a carbine.

So if free floating what’s holding the barrel into the block?

Did you remove the barrel band, like I mentioned above ?

I go try this Greg…thanks for help.

Here in Brazil the Guys have the same problems with cricket carbine…the POI change for left or right after one charge at 240bar… example:you shot one time,zero the rifle and go shot more one time….shit! The poi don’t is more the same… really is one big problem with crickets…what is happening,and why..? I check mounts,pellets,scope, but the problem is the cricket I know….unfortunately….

I have free floating forend on my cricket because when I tighten stock screw it bend cricket clamps – probably wrong machining of wood 🙁

Ed did in his Edguns, any POI shift(ing) related with the AT is nonexistent !

I’ve never really understood how many people would assume that the air tube of their rifles would change POI due to contraction and expansion during pressure changes, especially having not confirmed so by using proper methods. The explanation does sound logical. However, if this has been such a widely-established belief, why haven’t manufacturers done anything to counteract this issue?

I’ve never had this problem on my Air Arms S410 XTRA; mind you the S410 XTRA has a very long air tube. The shroud is supported by the air tube via a band. I’ve tested to see if this phenomenon existed by mounting a laser on the barrel shroud to try to detect any movement of the laser in relation to the scope throughout all pressure ranges of the air tube, and it simply didn’t exhibit any movement. Even from intentional bumping and pushing of the barrel and air tube sideways, up, and down the laser dot would always return to its true position (from meticulous visual observation).

Ernest tuned my .25 carbine directly before I received it .. he ground off the barrel band to free float the barrel as the slight changes in size of the airtube cause a poi shift if not floated as the pressure inthe tube changes

Thanks browndog . Makes me believe at least some of the voices are not lying to me !!

Joe, just got my .22 carbine back from ER. He free floated my barrel. Haven’t had a chance to shoot yet but will this coming weekend. Shooting JSB 18s @ ~920 fps
And I do remember a post about free-floating the barrel but I cannot remember where either :whistle:

Thanks Greg !!! For some reason I thought it was you that had done it …I found my POI shift today ..There was some grit in hammer opening . I cleaned it well and moly lubed it ..All back to good now . I guess hammer was hitting inconsistent… I GOTTA get a chrono !!!

Yes it was, but only on the Bullpups, not the riffles ……..

………. a chrony is a must have in the world/hobbies of PCPs. :winkn:
