I use both front and rear from Steve Baldwin. I would definitely get a Soule type ear, regardless of manufacturer. Baldwin are as good as any, but so are MVA. However, for front sights, the Baldwin has a real advantage. The sprit level is within the sight, instead of at the rear like the others. So the sun cannot affect it. I was once in competition on the range at Arcadia, Oklahoma. It is a north facing range. in the 300 yard rapid fire stage the sun was just at the right angle to explode into my sight like a supernova, making seeing the target imposible. From then on I carried electrical tape to cover the level in such situations. However. with the arcing trajectory of a buffalo rifle, you realy need that level beyond 200 yards.
