FX Wildcat .25 fan

My WC .25 MKI is now 39" long since I put a DonnyFL SUMO moderator on her!

I have a Mk.1 wildcat in 22. 

The barrels are held in place by set screws. One screw holds the barrel in the breech block, another holds the shroud to the barrel. On my wildcat those screws slid on the barrel and gave me weird POI shifts by having a semi blocked transfer port. I constantly remove/install my LCD's because I have two of them. I have a Ronin and tanto that I like to switch back and forth Between my wildcat and my 2240 co2 pistol. BTW a 2240 and a Donnie Ronin is almost soundless.
 
I see; I stand corrected. That's distressing. One of the reasons I bought a Wildcat .25 MKI is so that the barrel is fixed. I got tired of constantly having to retighten the barrel setscrew on my Impact. I guess no good deed goes unpunished. When removing / attaching moderators, I always keep a firm grasp on the shroud to keep it from turning anyway. The point's moot I guess though, because I plan on just keeping the SUMO on my WC permanently anyway though. Thanks for responding; I did not know that about the MKI. I'll be careful about that.
