Aimpoint will be a better choice, because the tube actually looks thinner than the Tasco's due to the conical design of the Aimpoint. I personally own 2 Tasco PDP3 and 2 Propoints. One PDP3 had it's intensity adjustment broke due to improper use of turning it off, and my dot went intermittent during matches. Tasco fixed it for $20 and shipping cost. So far it's been holding up, when I finally took it off my open gun I could not believe how many dings it had on the bottom portion of the tube from all the ejected brass hitting it. It still works and so does the other Propoints I have in my inventory. josh
