During a particularly rough patch at one place I was working overseas, I took an older and very reliable American made Burris 2-7 compact and mounted it on my M4. It got used a more there in 6 months than most scopes would see in lifetimes. It never failed in any way.
I later switched to a Leupold 1.5-5 illuminated LPVO and used that for years in the M.E.
The punchline is though, I have nothing bad to say about the older American made Burris scopes. I also have an older American made set of Burris 12x signature series binoculars that I have been using for 20 years now and have never felt the need to upgrade glass.
I have one of those 2-7 Burris Compact’s and it was on my main bump-in-the-night AR15 for over a decade. Contrary to what was stated above, that particular model has miles of eye relief and is a great “sneaker” scope for an AR. I remember when Art assured us all that Burris scopes had short eye relief. I shone a light through it with a ruler laid down to demonstrate the long eye relief but he still wouldn’t believe his lyin’ eyes.... good times.
I do feel that the 1-4 Zeiss V4 on the rifle now is a substantial upgrade, but the Burris is sitting in my safe awaiting its next mission. I’d never sell that thing. It’s worth waaay more than its “worth”, if that makes sense.
