Re: T2 vs T4
i went the non adjustable t4 for several reasons.
an adjustable cheekpiece is for me anyway, something which may fail. not that it is likely to happen ever, but its somthing to think about at least.
i had to have major surgery on my right cheek after having a glass smashed in it at work at the start of the year, and now have no feeling in most of it.. however, too much pressure on it really really hurts, problem is i cant tell when im putting too much pressure on it, as i cant feel it. so i need padding as opposed to hard surface....kind of hard to describe. so i use a stock pack.
my cheek does make it kind of hard to maintain consistant cheek weld, especially when halfway through putting pressure on the trigger, i get a massive jolt of pain to my face because im pushing too hard, lol, but i manage.
as to the butthook, get a notched leg harris bipod, problem solved, can adjust to any height you need in large increments, then you just take up the difference with the sandsock. it is working perfect for me, and i also find the ability to hold in the stock to my shoulder with my off hand is greatly improving how i drive the rifle under recoil. can now spot my own hits at 300, for instance.
plus 1 for the non adjust t4. cheaper, lighter, (more reliable?), K.I.S.S!!!!!!!
also as stated, put some mouse pad or misc other filler under your stock pack if you need the extra height... its pretty hard to shift once its in there and sand and mud wont stop it adjusting like id imagine a thumbwheel or screw system may....
either way you go, i think you will love your manners, they are a fantastic product right up there with the best in the world.
