    My .25 Bobcat MKII has been collecting dust for about a year, I had lost interest in shooting it, It just wasnt accurate at longer ranges.
    Yesterday, I decided to take it apart, removing the scope rail, I noticed the barrel was under tension from the rail (1mm)
    The more i thought about it, the more i got convinced it couldnt be good for accuracy, so today i did something….. 

    First, I removed the small dovetail on the front rail support

    Then I milled off the clamp under the scope rail, and made more room for clearance between the rail and shroud.

    My Bobcat now has a free-floating barrel, and two quick 10-shot 2″ groups just before dark at 100m REALLY made my day! 
    No target pictures, that meant wading through 4 feet of snow in trainers, but I seriously considered diving in just for the fun of it  :*)
    I think its possible to do even better now, cant wait to get back on the range, this really boosted my interest in the Bobcat.
    Im thinking of getting a smaller scope with short eye relief (MTC Connect?)to lighten the load on the rail, but it seems to hold zero like it is.

    WOW! This could be extremely valuable information to other Bobcat owners who sense an accuracy problem and are unable to find the culprit. I’m sure they will thank you immensely for discovering this and documenting your solution. Please do keep us informed of your further progress in tightening your long range groups. +1 for you, Cayin!

    I got several 5-shot 1MOA (100m) groups today, even a 7/8″ group that started with 4 shots at 0.5MOA.
    There is no doubt it helped MY rifle, but its still early to say it wont affect long-term mechanical stability.
    Dont do irreversible mods unless you dont care if it helps or not.

    Hi Cayin
    I think now your scope is a bit loose
    I want to suggest you to remove dovetail and attach your scope to the main rail then check if the accuracy get better or not.
    If you found it better you can buy a forward scope mount.

As far as i can tell, it seems to keep zero, but i will try that when i have the chance.
