Gamo Carbines

[PeakChick]

That's a very generous offer Paul, I'm touched. This is one I'll have to ruminate on. I have lots of air rifle pipe dreams on the burner.......  

A 40" OAL, .177 CFX (.22 for those that want or need the bigger whack) carbine does sound like it would be way too much fun though. I wish Gamo would offer one in the box. (I guess there is always the Stutzen)

Hmmm...all that, and dare I say "repeater"? A Gamo CO2 repeating carbine.  Such an animal?

What is the ideal barrel length if this project was carried on rifles with 5.0 and 5.5 calipers respectively ? Thanks.

There are always more than one way to skin a wabbit Stephanie.. And I guess that would apply to the CFX mod as well..

I don't think there would be significant difference in barrel length, regardless of caliber 4.5 (.177), 5.0 (.20) or 5.5 (.22). As I understand it, spring powered air rifles really only need about 12" max barrel length to be efficient. My BSA Lightning XL only has a 10" barrel and is a 900 fps rifle.
It's less about the actutal barrel length for me with this concept rifle, but more about the overall size of the gun for handling, pointability. About 40" is the max length I would want in a carbine sized rifle.

Hey Steph, if you decide to go through with this project, I will make you another stock for it. It will take me awhile to do, since I'm not completely set up at the moment and I'm waiting on 1 more tool, need to get a couple of others finished also. :0 I don't think that I would go much shorter on the stock, as it helps to hide the cocking linkage. A better grip and slightly higher cheek pad would be nice though.

I agree Mike, after looking at the forend on the stock, you are correct, it does hide the cocking linkage.

Well you did it ! I just called my friend in Istanbul who is selling his Gamo CF-30 tuned with 3.25 Maccari spring (37 spirs) to buy his gun. I did a lot of search and read many articles, forum debates on barrel length vs velocity, barrel shortening and decided to go on this project to come to an end with stg like TX200 HC.
I am planning to shorten the barrel length to 30 cm (original is 45 cms I guess) and maybe 2 cms from the bottom of the stock. I want to end with stg under 1 meter. Regards.

Good luck, and keep us posted with how it turns out.

Well, as a reference the barrel on my BSA Lightning XL is only 10", the barrel on a AA TX200HC is only 7". I generally would not cut a rifle barrel shorter than 12'.
