I have a T stock on my Walther LG55T.
It feels nice for sure, but I cant really use it as it should. My cheek is a bit on the rim, on the side of it. Has to do with height, distance to the peep, personal build etc. T stocks are meant for yr cheek to be cuddled in the middle. That also makes them a bit limited in use.
T stocks are a bit like t/h stocks. They look good from the outside, but often, they just dont fit/feel exactly right.
Havent found a standard t/h stock that really fits me either.
Its so personal.
A standard stock or standard cheekpiece doesnt have this. Its just plain, flat and a bit more 'one size fits all'
