Re: What does the milatary use
J. Unertle scopes were used before the USO's but USO's are still being used today on the A3's, but originally I believe the USO's were used in desert storm. Right now they are transiting to the A5 (a mistake IMHO) and I don't know if they will be used on them or if they will just stick with the S&B. Haven't found too many quotable sources on the A5 yet and the best source I seen was a clip on the M40A5 on the military channel which made it sound like they were primarily changing the barrel specs to a 20'' with a suppressor for urban conflicts. The only J. Unertle I own is on my 1903 Springfield and I have a Refeild on my M40. Also the way I understand it is the M40 used the Redfeild, the M40A1 Unertle or USO, the A3 with the S&B or USO, and the A5 is seems so far to be in the same day optics wise. By the way excuse me earlier on leaving the Unertle out, I just never associate that scope with that weapon, I usually associate it with the 1903.
