The Altitude is a mirror image of the Manners MCS-T, the only exception being the length of comb-- on the manners they cut a slot for the bolt when it is open to the rear, on the altitude they just removed that entire piece of the stock.

I have the Altitude on a LH Remington platform-- overall it is lighter than the MCS-T by a few ounces because they've found a way to mold the forearm with the same shape and dimensions but less material.

They can be purchased from Mesa Precision or Red Hawk Rifles--

I have a T3 .300wm that I am turning into a fast twist 270wsm and will be running the Altitude so that all my bolt rifles will have similar fit/feel/function
