sac, i would use the tub pin & a stiffer spring with the cp mods to try to get the lock time as short as possible.

here is a picture with the areas that need to be modified. i would start off with a coarse stone or a surface grinder with a white wheel if you have access to one then finish with a fine stone. the commercial cp can be moved a lot farther back than the military cp i would go at least .125 back on it. you can also shorten the tip of the cam so it doesn't have to push the cp any farther back than necessary to #+%% the rifle. if you use a shroud mounted safety the top of the cp will have to be modified for it to work. depending on how far farward the cp has moved it may be easier to grind a slot for the safety to catch like the swede turbo kit at the bottom of the page.
the one area should read "shorten sear height to .065-.050" had to may things going on at my desk


you can also use a sako trigger & re-grind a commercial cp to match the angle of the sear. this will move the cp forward a little shortening the lock time. you cannot use the sako trigger with a military sear.


the swedes had what was called a turbo kit for the m96 target rifles. it had a modified shroud, firing pin, cp & a stiffer spring.
they moved the cp way forward in them.

vns the turbo kit should work with a standard bolt housing
