I have a few of them mounted on various guns and they work well. I have not had any issues with mine. The eye box is a bit critical on 12x but that is expected for a scope that short. My first is on a Savage Striker in 260 Rem is a fun groundhog killing machine and shoots sub MOA with the big Burris. I killed groundhogs out to 300+ yards with it when I lived in Virginia. The scope also handles recoil well as I have one on a XP100R in 338/284. That thing is a beast. Lastly on a Virgin Valley Guns 243 Win barrel. It will shoot better than I can. I purchased these scopes about 20 years ago so I can't really speak to today's manufactured versions. I have had great success with Burris scopes though.
