Model 70 is the only one they catalog. Call them. For a front sight, I really like that NECG. Don't buy a blade, just order the plastic "test sights" from XS Sights. Go to the range and start shootin' and whittling. When you get done, measure what you have and order the appropriate height "white-stripe" FS from XS.
The NECG takes their proprietary "front load" blades. I believe XS's are standard dovetailed? I suggest confirming with Brockman if they will make you the base/sight. Once confirmed, send them your rifle and have them install it along with the NECG Masterpiece front sight that is adjustable. I have a couple and they are fine sights. Otherwise use the same front sight with Talley bases and their QD peep sight. My two bits.
