Since NF did not release a SFP 4-32 in NX8, I need to find something else. I want something that tracks great, since it will go on a 300 PRC. However, I would like it not to be as heavy as a ATACR, since its going on a 9lb hunting rifle. Prefer 20-32 power. The SHV i love, but wish it had higher power. Only thing I have found is the Viper PST 5-25. Are they any good?
