.177 barrel kits for compact Maverick?

[Patrick1]

Help!
Does anyone know where to get one? I’d like a 600mm but might go for 700mm. Utah Airguns only imports 500mm version. Trying to convert my .22 Compact Maverick to try smaller caliber.
I’ve read that there may have been issues with .177 FX barrels, but….

What do you plan to shoot that would require a barrel longer than 500mm?

I’m just trying to maximize shots and power and I’m thinking of shooting some slugs, too. Why?

The standard (superior STX) 177 liners are 1:18 so they don’t do well with slugs>13 grain (unless you’re at high elevation). The 500mm can shoot those at >1000fps, so there’s no sense in going longer unless you can get a heavy/slug liner. Last I checked, you could only buy the heavy 177 liners in Europe but FX forbids shipping of liners to the US. If you’re really determined, PM me and I’ll tell you how to get yourself a heavy /slug liner. However, you would then need to get a 600/700 mm barrel kit and a 177 jam nut and TP adapter to put it all together.

May be better to just get the 500, then. Thanks for your expertise! I had heard the longer fx barrels had some issues, too!
