FX MO 4 cocking lever tension

Hello Guys,

I bought a Mk 4 FX in .25 as a retirement gift a few months ago…love the gun, super accurate of course.

I’m primarily a hunter and am extremely frustrated with the lack of cocking lever tension. If I bump it, it pops open and if the gun is elevated, it’ll fully open, causing a mag removal to prevent a double feed.

I cannot determine a way to increase the closed tension. If anyone can assist, I’d appreciate it.
