I haven't been able to test out the Burris XTR II yet, but I've heard good things about them. I have heard that the glass quality is about on pad with Vortex's PST line, maybe slightly better. The Bushnell DMR is a solid scope with a good reputation for the overall value. The G2 reticle is favored by many shooters and are willing to give up some features just to have the reticle. The SWFA 5-20 is a great scope for the money, although of the 3 it's the most expensive of the bunch (unless you are going for the 10mil zero stop Bushnell scope). The glass in the SWFA will be the best of the bunch, and it has 10mil per rotation turrets. The reticle on the SWFA is liked by most and some don't care for it. I really like the reticle and I find it to be a solid improvement over the standard mil dot reticle. Out of the three scopes I'm very biased to the SWFA scope. I think that they are awesome scopes, especially for the money. Even Lowlight said they are a good value and a solid scope. You will probably be happy with any of the scopes mentioned, but I would choose the SWFA.
