I suppose what I was trying to say was that 3# is a decent trigger pull. I would not reccomend a lower pull on any rifle used for hunting.. Cold can number fingers and alter trigger dimensions. Also gloves delete some of the control we have on the trigger blade.. At 3# most can feel the blade before the rifle fires even with gloves on. Also most factory triggers are not precise enough to take being set very much lower than that. If a trigger must be set lower it almost certainly requires the trigger return spring be replaced. Shortening the factory spring is a very poor idea. You need the full extension of this spring to assure the trigger resets after firing. Creep and over travel are also adjustable and probably do more to harm a good trigger pull than just pull weight. You may also find a marked improvement in the trigger action by simply removing the barreled action and cleaning the trigger mechanism with a spray carberator cleaner.. This is basically a spray can of solvent and will remove old grease/oil and leave bare metal. Be certain to use this product outdoors!! After the cleaning I reccomend relubing with a dry film type lube, either a graphite or moly preperation reccommended for locks is fine. Do not use oil, silicone, or grease of any kind. These will all collect contamination and in a delicate mechanism dirt can prevent proper function. Anything further than turning screws is probably not a DIY project. Mistakes in trigger jobs can lead to trajedies. Finding a replacement trigger may also be a bit of a problem.. I could not find a replacement trigger in the current Brownells listings. You may contact M.H.Canjar Co. in 6510 Raleigh St. Arvada, CO 80003. Their catalog indicates they produce a model for the MK5 action. Their products are first rate.. But before the replacement I advise trying cleaning and proper lube.. good luck from the gunnut69
