I have had an AETEC on a mule of a 30-06 carbine for 5 years. It went threw scopes (admittedly cheap Tascos and bushnells) until I mounted it. I now have it on a 7mm BPR and it is still dead on and running. We have a bunch of Simmons products in our camp and they do well on Cf guns that take a beating in the field.
