The SR25 is too much gun for me considering how I'd use it.
I'm not a sniper, and I just could not bring myself to carry such a large rifle for the rifleman role. Very VERY cool, but huge, very costly, and not very practical. I've seen Nates SPR and it's very nice!
If needed, I could take the SPR into a house. Not much different than an A2 dimension-wise.
