I highly reccomend Joel's stocks , I've used several of his A5L's in the past , I like them moreso than alot of the synthetics because you can shape the grip a little bit more to fit your hand perfectly
here are two of the last ones I did ,
notice in this pic how the grip section is worked out , this is so that it fills my hand alot better
But if you must have a synthetic stock I would go with a Manners composite , they are a board sponser here and their T4A is everybit the stock that that McMillan is and then some , his lead time are probably alot shorter also.
here is my 308 working gun with a T4-A , its curently on its way back to me from getting a new paint job from Manners
