No more GM barrels in Mrods?

[FuzzyGrub]

Tom Holland over on AGN has been working with some crosman barrel engineers.  He reported today that crosman went to their own barrels in early 2018.         This seems to jive with the barrel I purchased in Jan 2019, which had an extremely tight choke, that resized the 25g JSB head.  I didn't have accuracy issues with it, but lost 60fps which some was barrel port not enlarged.  Others reported the same tight choke around that same timeframe. 

Now, outside of the tight choke, I don't recall seeing accuracy issues being reported here on GTA.  What say you 2019 25 cal mrod owners?

Thanks John!  Good to know.  I've got two of the original GM barrels that are very accurate, but can't help with the new ones.

How does one know if they have a green mountain barrel on their .25 or a crosman barrel?  I bought my marauder in 25 mainly cause of the better barrel.

It would be interesting to know if Crosman changed the twist rate.... The GM barrels were supposed to be a 15.5" twist....

Mike,

I have never seen any id markings on any of the barrels, be it crosman, GM, or LW ones supplied in their guns.   What is you gun mfg date in the serial number?


Bob,

I just checked the thread where I had talked about the choke.  I though I might have checked the twist rate, but wasn't recorded.   Now I think of it, that was my Liberty.

Wish this would not have happened, now I will have to find a used .25.

John The Crosman engineer is an active member here ask him. I’m curious also

[fatmike]

I have a build date of 8 18 so it looks like I got a crosman barrel. It seems to shoot fine but I'm left wondering if it could've been better. I think major production changes should be shared with the consumer so they know what they're buying.

I remember first shooting my GM and thinking something was wrong.  I only saw my sight in pellet hole.  Then realized I had dumped the magazine into the same hole at 25 yards.  Shocked because I had one of the infamous .22 barrels that was horrific.  Sold that rifle and glad I did!  The .25 now sits in a bullpup and it is a very nice combo.

When you cleaned the barrel, did you notice if the choke felt very tight?


Travis,

Hopefully John will read and confirm/deny.   I probably bugged him with too many IM's when he first joined GTA.

Following along, curious as well

Following.  If true, I wonder if the barrel could be ordered from GM directly?  If they're no longer making barrels for Crosman, hopefully they're free to sell direct?  Maybe we could even get longer blanks made?

Pick up the phone and call them!

I'd love to, after getting confirmation that they no longer make barrels for Crosman! 

[Airgun.Sniper]

 Yes I want to find out. I was on the phone with Kim today (Lil_Sis) she works at crosman I wished I would have asked I just assumed.

[FuzzyGrub]

I contacted GM a good number of years ago about 22 cal barrels for the Mrod.   I think the minimum quantity was 1000.   Far more than we would ever get with a group buy. 

[Airgun.Sniper]

 yeah thats a lot

I just PM'd him and asked him to comment here....

But wouldn't that be for making a .22 custom barrel?  I'm probably wrong... I'll call GM on Friday...  I would make sense that we could buy a "Crosman spec" .25 barrel blank on it's own- and possibly in a larger O.D. than currently available.  How awesome would that be?

What is Crosman spec anyway?  1:15.5 twist, but what's the land/groove? 

[Crosman Engineer]

John (FuzzyGrub) –You have tons of questions left.  At least 1 maybe 2…. 

Bob (rsterne) – Thanks for reaching out!  I try and get on there as much as I can but that is not always easy!  You post some awesome information and it is appreciated!

All – We are (and have been for a year or more) making our own .25 cal barrels.  I don’t know when exactly they went into production.  You can tell the difference between them by the crown.  The GM barrel has a deeper, almost recessed crown where the Crosman barrel has our standard target crown.  The quality of these barrels should be the same as our .22cal barrels. 

I cannot comment on what our barrel dimensions/parameters are.  I consider that something of a trade secret. 

I don’t know if GM sells barrels in small quantities but I know others do (Lothar, CZ and some others). 

Happy Shooting,
John
