I have an Intensity Optics 3.8-12x44 AO scope presently mounted on a 257R rifle that had been on a 6.5 Swede rifle. Probably around 80 rounds fired with scope mounted.....no problems....but then neither rifle has a severe recoil to test its durability. As for clarity and etc. of my scope....it is very good, comparable to top brand scopes selling for a heck of a lot more. This is not just my opinion, at least two other gents I shoot with on a regular basis, who prefer Leopolds, Burris and etc., have viewed thru my scope and said basically the same thing. However, mine has the aspherical type lens, which the 3-10X44 does not. If yours was the 2.8-10 intensity, it would be the aspherical lens too.
Yes, the Intensity scopes were by ATK. But, ATK no longer markets them under that brand. However they are still available as ATK's Weaver 40/44 line of scopes. The Weaver 40/44 3-30X44 sells for around $145. I know the same Intensity model can be bought for around $50, heck of a deal. I'm not sure all the Intensity scopes were made in the Philippines, but am fairly sure the aspherical lens type were and they are similiar to the Simmon's AETEC line, both having the aspherical lens and perhaps made in the same Philippine factory.
