I am deciding between the V3 and V5. I can get the V3 the first week in April or wait til at least July or august for the V5. I have other rifles with an FSP and the cowitnessing doesn't bother me. But am I going to wish I had the V5? I don't need 12 inches of rail,9 is plenty. The only thing that has me wondering is the FSP. It's going to be for CQB so the FSP is actually more durable but the versatility of the V5 is nice. It's a total toss up. Thoughts? Right now the only thing that is even tipping the scale is the wait time which is sort of a big deal.
